Title: recent advances in end-to-end automatic speech recognition.

Abstract: Recently, the speech community is seeing a significant trend of moving from deep neural network based hybrid modeling to end-to-end (E2E) modeling for automatic speech recognition (ASR). While E2E models achieve the state-of-the-art results in most benchmarks in terms of ASR accuracy, hybrid models are still used in a large proportion of commercial ASR systems at the current time. There are lots of practical factors that affect the production model deployment decision. Traditional hybrid models, being optimized for production for decades, are usually good at these factors. Without providing excellent solutions to all these factors, it is hard for E2E models to be widely commercialized. In this paper, we will overview the recent advances in E2E models, focusing on technologies addressing those challenges from the industry's perspective.

Speech Recognition is the task of converting spoken language into text. It involves recognizing the words spoken in an audio recording and transcribing them into a written format. The goal is to accurately transcribe the speech in real-time or from recorded audio, taking into account factors such as accents, speaking speed, and background noise.

Classification of Arabic fricative consonants according to their places of articulation

<span>Many technology systems have used voice recognition applications to transcribe a speaker’s speech into text that can be used by these systems. One of the most complex tasks in speech identification is to know, which acoustic cues will be used to classify sounds. This study presents an approach for characterizing Arabic fricative consonants in two groups (sibilant and non-sibilant). From an acoustic point of view, our approach is based on the analysis of the energy distribution, in frequency bands, in a syllable of the consonant-vowel type. From a practical point of view, our technique has been implemented, in the MATLAB software, and tested on a corpus built in our laboratory. The results obtained show that the percentage energy distribution in a speech signal is a very powerful parameter in the classification of Arabic fricatives. We obtained an accuracy of 92% for non-sibilant consonants /f, χ, ɣ, ʕ, ћ, and h/, 84% for sibilants /s, sҁ, z, Ӡ and ∫/, and 89% for the whole classification rate. In comparison to other algorithms based on neural networks and support vector machines (SVM), our classification system was able to provide a higher classification rate.</span>


Abstract Voice recognition has become an integral part of our lives, commonly used in call centers and as part of virtual assistants. However, voice recognition is increasingly applied to more industrial uses. Each of these use cases has unique characteristics that may impact the effectiveness of voice recognition, which could impact industrial productivity, performance, or even safety. One of the most prominent among them is the unique background noises that are dominant in each industry. The existence of different machinery and different work layouts are primary contributors to this. Another important characteristic is the type of communication that is present in these settings. Daily communication often involves longer sentences uttered under relatively silent conditions, whereas communication in industrial settings is often short and conducted in loud conditions. In this study, we demonstrated the importance of taking these two elements into account by comparing the performances of two voice recognition algorithms under several background noise conditions: a regular Convolutional Neural Network (CNN) based voice recognition algorithm to an Auto Speech Recognition (ASR) based model with a denoising module. Our results indicate that there is a significant performance drop between the typical background noise use (white noise) and the rest of the background noises. Also, our custom ASR model with the denoising module outperformed the CNN based model with an overall performance increase between 14-35% across all background noises. . Both results give proof that specialized voice recognition algorithms need to be developed for these environments to reliably deploy them as control mechanisms.

Supervised Learning Methods and Applications in Medical Research

Machine Learning (ML) and Artificial Intelligence (AI) methods are transforming many commercial and academic areas, including feature extraction, autonomous driving, computational linguistics, and voice recognition. These new technologies are now having a significant effect in radiography, forensics, and many other areas where the accessibility of automated systems may improve the precision and repeatability of essential job performance. In this systematic review, we begin by providing a short overview of the different methods that are currently being developed, with a particular emphasis on those utilized in biomedical studies.

Steering a Robotic Wheelchair Based on Voice Recognition System Using Convolutional Neural Networks

Many wheelchair people depend on others to control the movement of their wheelchairs, which significantly influences their independence and quality of life. Smart wheelchairs offer a degree of self-dependence and freedom to drive their own vehicles. In this work, we designed and implemented a low-cost software and hardware method to steer a robotic wheelchair. Moreover, from our method, we developed our own Android mobile app based on Flutter software. A convolutional neural network (CNN)-based network-in-network (NIN) structure approach integrated with a voice recognition model was also developed and configured to build the mobile app. The technique was also implemented and configured using an offline Wi-Fi network hotspot between software and hardware components. Five voice commands (yes, no, left, right, and stop) guided and controlled the wheelchair through the Raspberry Pi and DC motor drives. The overall system was evaluated based on a trained and validated English speech corpus by Arabic native speakers for isolated words to assess the performance of the Android OS application. The maneuverability performance of indoor and outdoor navigation was also evaluated in terms of accuracy. The results indicated a degree of accuracy of approximately 87.2% of the accurate prediction of some of the five voice commands. Additionally, in the real-time performance test, the root-mean-square deviation (RMSD) values between the planned and actual nodes for indoor/outdoor maneuvering were 1.721 × 10−5 and 1.743 × 10−5, respectively.

Voice Versus Keyboard and Mouse for Text Creation on Arabic User Interfaces

Voice User Interfaces (VUIs) are increasingly popular owing to improvements in automatic speech recognition. However, the understanding of user interaction with VUIs, particularly Arabic VUIs, remains limited. Hence, this research compared user performance, learnability, and satisfaction when using voice and keyboard-and-mouse input modalities for text creation on Arabic user interfaces. A Voice-enabled Email Interface (VEI) and a Traditional Email Interface (TEI) were developed. Forty participants attempted pre-prepared and self-generated message creation tasks using voice on the VEI, and the keyboard-and-mouse modal on the TEI. The results showed that participants were faster (by 1.76 to 2.67 minutes) in pre-prepared message creation using voice than using the keyboard and mouse. Participants were also faster (by 1.72 to 2.49 minutes) in self-generated message creation using voice than using the keyboard and mouse. Although the learning curves were more efficient with the VEI, more participants were satisfied with the TEI. With the VEI, participants reported problems, such as misrecognitions and misspellings, but were satisfied about the visibility of possible executable commands and about the overall accuracy of voice recognition.

Digital Technology in Diagnostic Breast Pathology and Immunohistochemistry

Digital technology has been used in the field of diagnostic breast pathology and immunohistochemistry (IHC) for decades. Examples include automated tissue processing and staining, digital data processing, storing and management, voice recognition systems, and digital technology-based production of antibodies and other IHC reagents. However, the recent application of whole slide imaging technology and artificial intelligence (AI)-based tools has attracted a lot of attention. The use of AI tools in breast pathology is discussed briefly as it is covered in other reviews. Here, we present the main application of digital technology in IHC. This includes automation of IHC staining, using image analysis systems and computer vision technology to interpret IHC staining, and the use of AI-based tools to predict marker expression from haematoxylin and eosin-stained digitalized images.

Designing Depression Screening Chatbots

Advances in voice recognition, natural language processing, and artificial intelligence have led to the increasing availability and use of conversational agents (chatbots) in different settings. Chatbots are systems that mimic human dialogue interaction through text or voice. This paper describes a series of design considerations for integrating chatbots interfaces with health services. The present paper is part of ongoing work that explores the overall implementation of chatbots in the healthcare context. The findings have been created using a research through design process, combining (1) literature survey of existing body of knowledge on designing chatbots, (2) analysis on state-of-the-practice in using chatbots as service interfaces, and (3) generative process of designing a chatbot interface for depression screening. In this paper we describe considerations that would be useful for the design of a chatbot for a healthcare context.

Early Prediction of DNN Activation Using Hierarchical Computations

Deep Neural Networks (DNNs) have set state-of-the-art performance numbers in diverse fields of electronics (computer vision, voice recognition), biology, bioinformatics, etc. However, the process of learning (training) from the data and application of the learnt information (inference) process requires huge computational resources. Approximate computing is a common method to reduce computation cost, but it introduces loss in task accuracy, which limits their application. Using an inherent property of Rectified Linear Unit (ReLU), a popular activation function, we propose a mathematical model to perform MAC operation using reduced precision for predicting negative values early. We also propose a method to perform hierarchical computation to achieve the same results as IEEE754 full precision compute. Applying this method on ResNet50 and VGG16 shows that up to 80% of ReLU zeros (which is 50% of all ReLU outputs) can be predicted and detected early by using just 3 out of 23 mantissa bits. This method is equally applicable to other floating-point representations.

Metrics details

Among the other modes of communication, such as text, body language, facial expressions, and so on, human beings employ speech as the most common. It contains a great deal of information, including the speaker’s feelings. Detecting the speaker’s emotions from his or her speech has shown to be quite useful in a variety of real-world applications. The dataset development, feature extraction, feature selection/dimensionality reduction, and classification are the four primary processes in the Speech Emotion Recognition process. In this context, more than 70 studies are thoroughly examined in terms of their databases, emotions, features extracted, and classifiers employed. The databases, characteristics, extraction and classification methods, as well as the results, are all thoroughly examined. The study also includes a comparative analysis of these research papers.

Speech Recognition

For centuries, engineers and scientists were intrigued by the idea of creating a machine that can converse with humans fluently in a natural spoken language. The earlier examples of this fascination can be found in science fiction movies in the 60s and 70s.

Stanley Kubrick’s 1968 movie “2001: A Space Odyssey” and George Lucas’ famous Star Wars saga, for instance, had an intelligent computer named “HAL” and mobile droids like R2D2 and C3PO respectively, that could move around interacting with people and other droids in natural human language.

Among the earliest genuine attempts of speech recognition was a “digit recognizer” called Audrey (1952) Bell Laboratories which could only recognize spoken numbers, Shoebox by IBM (1962) which could understand 16 words in English, and Harpy (1976) by Carnegie Mellon which could comprehend 1011 words.

In a significant breakthrough, the development of the Markov model in the 1980s was able to determine a word from an unknown sound, without relying on speech patterns or fixed templates. It led to the invention of several industrial and business applications. But all speech recognition systems in the 80s had a big flaw: you had to take a break between each spoken word.

The world had to wait until 1997 to get a glimpse of the world’s first continuous speech recognizer – Dragon NaturallySpeaking. Capable of understanding 100 words per minute without any pause, it is still in use today.

In a human to machine interface, a speech signal is transformed into an analog and digital waveform which can be understood by the machine. Speech technologies are vastly used and have unlimited uses. These technologies enable devices to respond correctly and reliably to human voices and provide useful and valuable services.

latest research papers on speech recognition

The field of generative AI is rapidly evolving, showing remarkable potential to augment human creativity and self-expression. In 2022, we made the leap from image generation to video generation in the span of a few months. And at this year’s Meta Connect, we announced several new developments , including Emu , our first foundational model for image generation. Technology from Emu underpins many of our generative AI experiences, some AI image editing tools for Instagram that let you take a photo and change its visual style or background, and the Imagine feature within Meta AI that lets you generate photorealistic images directly in messages with that assistant or in group chats across our family of apps. Our work in this exciting field is ongoing, and today, we’re announcing new research into controlled image editing based solely on text instructions and a method for text-to-video generation based on diffusion models.

Emu Video: A simple factorized method for high-quality video generation

Whether or not you’ve personally used an AI image generation tool, you’ve likely seen the results: Visually distinct, often highly stylized and detailed, these images on their own can be quite striking—and the impact increases when you bring them to life by adding movement.

With Emu Video, which leverages our Emu model, we present a simple method for text-to-video generation based on diffusion models. This is a unified architecture for video generation tasks that can respond to a variety of inputs: text only, image only, and both text and image. We’ve split the process into two steps: first, generating images conditioned on a text prompt, and then generating video conditioned on both the text and the generated image. This “factorized” or split approach to video generation lets us train video generation models efficiently. We show that factorized video generation can be implemented via a single diffusion model. We present critical design decisions, like adjusting noise schedules for video diffusion, and multi-stage training that allows us to directly generate higher-resolution videos.

Unlike prior work that requires a deep cascade of models (e.g., five models for Make-A-Video ), our state-of-the-art approach is simple to implement and uses just two diffusion models to generate 512x512 four-second long videos at 16 frames per second. In human evaluations, our video generations are strongly preferred compared to prior work—in fact, this model was preferred over Make-A-Video by 96% of respondents based on quality and by 85% of respondents based on faithfulness to the text prompt. Finally, the same model can “animate” user-provided images based on a text prompt where it once again sets a new state-of-the-art outperforming prior work by a significant margin.

Emu Edit: Precise image editing via recognition and generation tasks

Of course, the use of generative AI is often a process. You try a prompt, the generated image isn’t quite what you had in mind, so you continue tweaking the prompt until you get to a more desired outcome. That’s why prompt engineering has become a thing. And while instructable image generative models have made significant strides in recent years, they still face limitations when it comes to offering precise control. That’s why we’re introducing Emu Edit, a novel approach that aims to streamline various image manipulation tasks and bring enhanced capabilities and precision to image editing.

Emu Edit is capable of free-form editing through instructions, encompassing tasks such as local and global editing, removing and adding a background, color and geometry transformations, detection and segmentation, and more. Current methods often lean towards either over-modifying or under-performing on various editing tasks. We argue that the primary objective shouldn’t just be about producing a “believable” image. Instead, the model should focus on precisely altering only the pixels relevant to the edit request. Unlike many generative AI models today, Emu Edit precisely follows instructions, ensuring that pixels in the input image unrelated to the instructions remain untouched. For instance, when adding the text “Aloha!” to a baseball cap, the cap itself should remain unchanged.

Our key insight is that incorporating computer vision tasks as instructions to image generation models offers unprecedented control in image generation and editing. Through a detailed examination of both local and global editing tasks, we highlight the vast potential of Emu Edit in executing detailed edit instructions.

In order to train the model, we’ve developed a dataset that contains 10 million synthesized samples, each including an input image, a description of the task to be performed, and the targeted output image. We believe it’s the largest dataset of its kind to date. As a result, our model displays unprecedented edit results in terms of both instruction faithfulness and image quality. In our evaluations, Emu Edit demonstrates superior performance over current methods, producing new state-of-the-art results in both qualitative and quantitative evaluations for a range of image editing tasks.

The road ahead

Although this work is purely fundamental research right now, the potential use cases are clearly evident. Imagine generating your own animated stickers or clever GIFs on the fly to send in the group chat rather than having to search for the perfect media for your reply. Or editing your own photos and images, no technical skills required. Or adding some extra oomph to your Instagram posts by animating static photos. Or generating something entirely new.

While certainly no replacement for professional artists and animators, Emu Video, Emu Edit, and new technologies like them could help people express themselves in new ways—from an art director ideating on a new concept or a creator livening up their latest reel to a best friend sharing a unique birthday greeting. And we think that’s something worth celebrating.

Microsoft releases AI tool for photorealistic copying of faces and voices

In response to criticism that Azure AI Speech was simply a ‘deepfakes creator’, Microsoft said it had implemented safeguards

Microsoft announced its latest contribution to the artificial intelligence race at its developer conference this week: software that can generate new avatars and voices or replicate the existing appearance and speech of a user – raising concerns that it could supercharge the creation of deepfakes , AI-made videos of events that didn’t happen.

Announced at Microsoft Ignite 2023, Azure AI Speech is trained with human images and allows users to input a script that can then be “read” aloud by a photorealistic avatar created with artificial intelligence. Users can either choose a preloaded Microsoft avatar or upload footage of a person whose voice and likeness they want to replicate. Microsoft said in a blog post published on Wednesday that the tool could be used to build “conversational agents, virtual assistants, chatbots and more”.

The post reads: “Customers can choose either a prebuilt or a custom neural voice for their avatar. If the same person’s voice and likeness are used for both the custom neural voice and the custom text to speech avatar, the avatar will closely resemble that person.”

The company said the new text-to-speech software is being released with a variety of limits and safeguards to prevent misuse. “As part of Microsoft’s commitment to responsible AI, text to speech avatar is designed with the intention of protecting the rights of individuals and society, fostering transparent human-computer interaction, and counteracting the proliferation of harmful deepfakes and misleading content,” the company said.

“Customers can upload their own video recording of avatar talent, which the feature uses to train a synthetic video of the custom avatar speaking,” the blog post reads. “Avatar talent” is a human posing for the AI’s proverbial camera.

The announcement quickly elicited criticism that Microsoft had launched a “deepfakes creator” – which would more easily allow a person’s likeness to be replicated and made to say and do things the person has not said or done. Microsoft’s own president said in May that deepfakes are his “biggest concern” when it comes to the rise of artificial intelligence.

In a statement, the company pushed back on the criticism, saying the customized avatars are now a “limited access” tool for which customers have to apply and be approved for by Microsoft. Users will also be required to disclose when AI was used to create a synthetic voice or avatar.

“With these safeguards in place, we help limit potential risks and empower customers to infuse advanced voice and speech capabilities into their AI applications in a transparent and safe manner,” Sarah Bird of Microsoft’s responsible AI engineering division said in a statement.

The text-to-speech avatar maker is the latest tool as major tech firms have raced to capitalize on the artificial intelligence boom of recent years. After the runaway popularity of ChatGPT – launched by Microsoft-backed firm OpenAI – companies like Meta and Google have pushed their own artificial intelligence tools to the market.

after newsletter promotion

With AI’s rise has come growing concerns about the capabilities of the technology, with the OpenAI CEO, Sam Altman, warning Congress that it could be used for election interference and safeguards must be implemented.

Deepfakes pose particular danger when it comes to election interference, experts say . Microsoft launched a tool earlier this month to allow politicians and campaigns to authenticate and watermark their videos to verify their legitimacy and prevent the spread of deepfakes. Meta announced a policy this week requiring the disclosure of the use of AI in political ads and banning campaigns from using Meta’s own generative AI tools for ads.

X Sues Media Matters Over Research on Ads Next to Antisemitic Posts

X asked a federal court to order the advocacy group to take down its findings, accusing it of “manipulating the algorithms.”

A view of X’s masonry headquarters from across a city intersection.

By Kate Conger and Ryan Mac

X, the social media service formerly known as Twitter, sued Media Matters in federal court on Monday after the advocacy organization published research showing that ads on X appeared next to antisemitic content.

A post last week from Elon Musk that endorsed an antisemitic conspiracy theory, which he wrote a day before the Media Matters research was published, kicked off an advertiser exodus, with major brands like IBM, Apple, Warner Bros. Discovery and Sony pausing their spending on the platform.

X has rejected Media Matters’ findings, saying they were not representative of a regular user’s experience on the platform. On Friday, Mr. Musk promised a “thermonuclear lawsuit” against Media Matters and its backers.

The lawsuit, filed in U.S. District Court for the Northern District of Texas, claims that Media Matters tried to damage X’s relationships with advertisers. “Media Matters has manipulated the algorithms governing the user experience on X to bypass safeguards and create images of X’s largest advertisers’ paid posts adjacent to racist, incendiary content, leaving the false impression that these pairings are anything but what they actually are: manufactured, inorganic and extraordinarily rare,” lawyers for X wrote in the complaint.

Angelo Carusone, the president of Media Matters, said in a statement, “This is a frivolous lawsuit meant to bully X’s critics into silence.” He added that his organization “stands behind its reporting and looks forward to winning in court.”

On Monday night, Ken Paxton, the Texas attorney general , also announced that his office would open an investigation into Media Matters for “potential fraudulent activity.”

Brands have been hesitant to advertise on X since Mr. Musk bought the company a year ago and said he would relax its content-moderation policies. X has sought to woo hesitant advertisers back to the platform, an initiative that has been overseen by Linda Yaccarino, a longtime advertising executive who became X’s chief executive in June.

But Mr. Musk’s post on Wednesday , in which he agreed with a post from an X account accusing Jewish communities of pushing “hatred against whites that they claim to want people to stop using against them,” was a setback.

“You have said the actual truth,” Mr. Musk replied to the post.

Jewish groups quickly condemned the statement that Mr. Musk endorsed, likening it to the “ Great Replacement Theory ,” a conspiracy theory that claims minorities are replacing white European populations as part of a coordinated effort by Jewish people. The White House condemned Mr. Musk’s remark, and top-tier brands quickly pulled their advertising off X.

Mr. Musk said in a post to X on Sunday that claims that he was antisemitic were untrue. “Nothing could be further from the truth,” he wrote.

In its lawsuit, X asked the court to order Media Matters to take down its published research. The lawsuit also seeks unspecified monetary damages and lawyers’ fees.

Ms. Yaccarino said in a statement that the X account that Media Matters had used in its research was the only account that saw some of the ads next to the antisemitic posts in question. In the case of Apple, its ad was placed next to an antisemitic post and viewed by another user, she added.

“If you know me, you know I’m committed to truth and fairness,” Ms. Yaccarino said in a post on X . “Data wins over manipulation or allegations. Don’t be manipulated. Stand with X.”

During an all-staff meeting on Monday, Ms. Yaccarino said she had discussed the issue with advertisers and was committed to defending X, according to audio of the meeting heard by The New York Times. In those conversations, some advertisers had asked her to be more communicative about problems to get in front of them, and to share more data about how ads are displayed on the platform, she said.

“We want to work with all of our partners who stand with us and believe in the power and the necessity of free speech,” Ms. Yaccarino said. “Sometimes in life and in business, standing for your values is the truly defining thing that makes leaders, and we’re going to hold on to that and keep pushing forward. No critic is ever going to deter us from our mission to keep fighting and protecting free speech .”

In the roughly 30-minute meeting, Ms. Yaccarino focused the blame on Media Matters and did not address Mr. Musk’s endorsement of the antisemitic post.

She also encouraged employees to be frugal during a period of decreased revenue caused by the advertiser pauses and think of ways the company could bring in more money.

“I would say be as fiscally responsible as possible,” the chief executive told her workers. “And that’s on a spectrum of critical-only and necessary travel to being a good steward of anything that might be related to an expenditure at the company.”
