Neural Text-to-Speech—along with recent milestones in computer vision and question answering—is part of a larger Azure AI mission to provide relevant, meaningful AI solutions and services that work better for people because they better capture how people learn and work—with improved vision, knowledge understanding, and speech capabilities. At the center of these efforts is XYZ-code, a joint representation of three cognitive attributes: monolingual text (X), audio or visual sensory signals (Y), and multilingual (Z). For more information about these efforts, read the XYZ-code blog post .
Neural Text-to-Speech (opens in new tab) (Neural TTS), a powerful speech synthesis capability of Azure Cognitive Services (opens in new tab) , enables developers to convert text to lifelike speech. It is used in voice assistant scenarios, content read aloud capabilities, accessibility tools, and more. Neural TTS has now reached a significant milestone in Azure, with a new generation of Neural TTS model called Uni-TTSv4, whose quality shows no significant difference from sentence-level natural speech recordings.
Microsoft debuted the original technology three years ago, with close to human-parity (opens in new tab) quality. This resulted in TTS audio that was more fluid, natural sounding, and better articulated. Since then, Neural TTS has been incorporated into Microsoft flagship products such as Edge Read Aloud (opens in new tab) , Immersive Reader (opens in new tab) , and Word Read Aloud (opens in new tab) . It’s also been adopted by many customers such as AT&T (opens in new tab) , Duolingo (opens in new tab) , Progressive (opens in new tab) , and more. Users can choose from multiple pre-set voices or record and upload their own sample to create custom voices instead. Over 110 languages are supported, including a wide array of language variants, also known as locales.
The latest version of the model, Uni-TTSv4, is now shipping into production on a first set of eight voices (shown in the table below). We will continue to roll out the new model architecture to the remaining 110-plus languages and Custom Neural Voice (opens in new tab) in the coming milestone. Our users will automatically get significantly better-quality TTS through the Azure TTS API (opens in new tab) , Microsoft Office, and Edge browser.
Measuring TTS quality
Text-to-speech quality is measured by the Mean Opinion Score (MOS), a widely recognized scoring method for speech quality evaluation. For MOS studies, participants rate speech characteristics for both recordings of peoples’ voices and TTS voices on a five-point scale. These characteristics include sound quality, pronunciation, speaking rate, and articulation. For any model improvement, we first conduct a side-by-side comparative MOS test ( CMOS (opens in new tab) ) with production models. Then, we do a blind MOS test on the held-out recording set (recordings not used in training) and the TTS-synthesized audio and measure the difference between the two MOS scores.
During research of the new model, Microsoft submitted the Uni-TTSv4 system to Blizzard Challenge 2021 under its code name, DelightfulTTS. Our paper, “ DelightfulTTS: The Microsoft Speech Synthesis System for Blizzard Challenge 2021 ,” provides in-depth detail of our research and the results. The Blizzard Challenge is a well-known TTS benchmark organized by world-class experts in TTS fields, and it conducts large-scale MOS tests on multiple TTS systems with hundreds of listeners. Results from Blizzard Challenge 2021 demonstrate that the voice built with the new model shows no significant difference from natural speech on the common dataset.

Measurement results for Uni-TTSv4 and comparison
The MOS scores below are based on samples produced by the Uni-TTSv4 model under the constraints of real-time performance requirements.
A Wilcoxon signed-rank test (opens in new tab) was used to determine whether the MOS scores differed significantly between the held-out recordings and TTS. A p-value less than 0.05 (typically ≤ 0.05) is statistically significant and a p-value higher than 0.05 (> 0.05) is not statistically significant. A positive CMOS number shows gain over production, which shows it is more highly preferred by people judging the voice in terms of naturalness.

How Uni-TTSv4 works to better represent human speech
Over the past 3 years, Microsoft has been improving its engine to make TTS that more closely aligns with human speech. While the typical Neural TTS quality of synthesized speech has been impressive, the perceived quality and naturalness still have space to improve compared to human speech recordings. We found this is particularly the case when people listen to TTS for a while. It is in the very subtle nuances, such as variations in tone or pitch, that people are able to tell whether a speech is generated by AI.
Why is it so hard for a TTS voice to reflect human vocal expression more closely? Human speech is usually rich and dynamic. With different emotions and in different contexts, a word is spoken differently. And in many languages this difference can be very subtle. The expressions of a TTS voice are modeled with various acoustic parameters. Currently it is not very efficient for those parameters to model all the coarse-grained and fine-grained details on the acoustic spectrum of human speech. TTS is also a typical one-to-many mapping problem where there could be multiple varying speech outputs (for example, pitch, duration, speaker, prosody, style, and others) for a given text input. Thus, modeling such variation information is important to improve the expressiveness and naturalness of synthesized speech.
To achieve these improvements in quality and naturalness, Uni-TTSv4 introduces two significant updates in acoustic modeling. In general, transformer models learn the global interaction while convolutions efficiently capture local correlations. First, there’s a new architecture with transformer and convolution blocks, which better model the local and global dependencies in the acoustic model. Second, we model variation information systematically from both explicit perspectives (speaker ID, language ID, pitch, and duration) and implicit perspectives (utterance-level and phoneme-level prosody). These perspectives use supervised and unsupervised learning respectively, which ensures end-to-end audio naturalness and expressiveness. This method achieves a good balance between model performance and controllability, as illustrated below:
![text to speech microsoft Acoustic model and vocoder diagram, described from left to right. Text is input into a text encoder. An arrow points from the text encoder to a spectrum decoder. Both implicit and explicit information are input between the encoder and decoder stages. From the Spectrum decoder, and arrow points to a vocoder. The vocoder points to an audio wave visual representation, representing conversion from mel spectrum into audio samples.](https://www.microsoft.com/en-us/research/uploads/prod/2021/12/text-encoder.jpg)
To achieve better voice quality, the basic modelling block needs fundamental improvement. The global and local interactions are especially important for non-autoregressive TTS, considering it has a longer output sequence than machine translation or speech recognition in the decoder, and each frame in the decoder cannot see its history as the autoregressive model does. So, we designed a new modelling block which combines the best of transformer and convolution, where self-attention learns the global interaction while the convolutions efficiently capture the local correlations.
![text to speech microsoft Improved conformer module diagram from bottom to top. Four layers represented by boxes are each joined by a sub-layer labeled “Add and Norm.” Two arrows at the bottom of each layer point to the base layer as well as the sub-layer boxes. The first layer is labeled “Conv Feed Forward.” The second layer is “Depthwise Convolution.” The Third is “Self Attention.” The fourth is “Conv Feed Forward.”](https://www.microsoft.com/en-us/research/uploads/prod/2021/12/feed.jpg)
The new variance adaptor, based on FastSpeech2 , introduces a hierarchical implicit information modelling pipeline from utterance-level prosody and phoneme-level prosody perspectives, together with the explicit information like duration, pitch, speaker ID, and language ID. Modeling these variations can effectively mitigate the one-to-many mapping problem and improves the expressiveness and fidelity of synthesized speech.
![text to speech microsoft Variance adaptor diagram from bottom to top. Along the left side, an arrow moves from bottom to top, ending in a circle labeled “LR” and showing the full modeling process. To the right of the vertical arrow, Language and Speaker ID are added to hidden embeddings. Next, vectors are predicted with an utterance-level prosody predictor and then a phoneme-level prosody predictor. Then, a pitch predictor is used, and the hidden representation is expanded with a duration predictor.](https://www.microsoft.com/en-us/research/uploads/prod/2021/12/predictor.jpg)

What is speech to text?
- 3 contributors
Azure AI Speech service offers advanced speech to text capabilities. This feature supports both real-time and batch transcription, providing versatile solutions for converting audio streams into text.
Core Features
The speech to text service offers the following core features:
- Real-time transcription: Instant transcription with intermediate results for live audio inputs.
- Fast transcription : Fastest synchronous output for situations with predictable latency.
- Batch transcription : Efficient processing for large volumes of prerecorded audio.
- Custom speech : Models with enhanced accuracy for specific domains and conditions.
Real-time speech to text
Real-time speech to text transcribes audio as it's recognized from a microphone or file. It's ideal for applications requiring immediate transcription, such as:
- Transcriptions, captions, or subtitles for live meetings : Real-time audio transcription for accessibility and record-keeping.
- Diarization : Identifying and distinguishing between different speakers in the audio.
- Pronunciation assessment : Evaluating and providing feedback on pronunciation accuracy.
- Call center agents assist : Providing real-time transcription to assist customer service representatives.
- Dictation : Transcribing spoken words into written text for documentation purposes.
- Voice agents : Enabling interactive voice response systems to transcribe user queries and commands.
Real-time speech to text can be accessed via the Speech SDK, Speech CLI, and REST API, allowing integration into various applications and workflows. Real-time speech to text is available via the Speech SDK , the Speech CLI , and REST APIs such as the Fast transcription API .
Fast transcription (Preview)
Fast transcription API is used to transcribe audio files with returning results synchronously and faster than real-time audio. Use fast transcription in the scenarios that you need the transcript of an audio recording as quickly as possible with predictable latency, such as:
- Quick audio or video transcription and subtitles : Quickly get a transcription of an entire video or audio file in one go.
- Video translation : Immediately get new subtitles for a video if you have audio in different languages.
Fast transcription API is only available via the speech to text REST API version 2024-05-15-preview and later.
To get started with fast transcription, see use the fast transcription API (preview) .
Batch transcription API
Batch transcription is designed for transcribing large amounts of audio stored in files. This method processes audio asynchronously and is suited for:
- Transcriptions, captions, or subtitles for prerecorded audio : Converting stored audio content into text.
- Contact center post-call analytics : Analyzing recorded calls to extract valuable insights.
- Diarization : Differentiating between speakers in recorded audio.
Batch transcription is available via:
Speech to text REST API : Facilitates batch processing with the flexibility of RESTful calls. To get started, see How to use batch transcription and Batch transcription samples .
Speech CLI : Supports both real-time and batch transcription, making it easy to manage transcription tasks. For Speech CLI help with batch transcriptions, run the following command:
Custom speech
With custom speech , you can evaluate and improve the accuracy of speech recognition for your applications and products. A custom speech model can be used for real-time speech to text , speech translation , and batch transcription .
A hosted deployment endpoint isn't required to use custom speech with the Batch transcription API . You can conserve resources if the custom speech model is only used for batch transcription. For more information, see Speech service pricing .
Out of the box, speech recognition utilizes a Universal Language Model as a base model that is trained with Microsoft-owned data and reflects commonly used spoken language. The base model is pretrained with dialects and phonetics representing various common domains. When you make a speech recognition request, the most recent base model for each supported language is used by default. The base model works well in most speech recognition scenarios.
Custom speech allows you to tailor the speech recognition model to better suit your application's specific needs. This can be particularly useful for:
- Improving recognition of domain-specific vocabulary : Train the model with text data relevant to your field.
- Enhancing accuracy for specific audio conditions : Use audio data with reference transcriptions to refine the model.
For more information about custom speech, see the custom speech overview and the speech to text REST API documentation.
For details about customization options per language and locale, see the language and voice support for the Speech service documentation.

Google's former CEO says the tech giant is losing out to OpenAI and Anthropic because staff are working from home
- OpenAI and Anthropic have been giving Google a run for its money in the AI race.
- Ex-Google CEO Eric Schmidt says the company's work-from-home policy is hurting its competitiveness.

Remote working has blunted Google's competitiveness in the AI race , says the company's former CEO and chairman, Eric Schmidt .
Schmidt was speaking to students at Stanford University during a lecture in April when he was asked about the lead that startups like OpenAI and Anthropic currently have over Google when it comes to AI .
A recording of Schmidt's lecture was published on Stanford Online's YouTube channel on Tuesday.
"Google decided that work-life balance and going home early and working from home was more important than winning," Schmidt said."And the reason the startups work is because the people work like hell."
"I'm sorry to be so blunt, but the fact of the matter is, if you all leave the university and go found a company, you're not going to let people work from home and only come in one day a week if you want to compete against the other startups."
Representatives for Google didn't immediately respond to a request for comment from Business Insider sent outside regular business hours.
Schmidt was Google's CEO and chairman from 2001 and 2011 before handing the reins back to the search giant's co-founder Larry Page .
He went on to serve as Google's executive chairman and technical advisor before finally departing the company in early 2020.
Schmidt isn't the only executive who thinks remote working has hurt businesses. JPMorgan CEO Jamie Dimon , for one, has been an outspoken advocate for staff to head back to the office.
"It doesn't work for younger kids in apprenticeships, it doesn't really work for creativity and spontaneity, it doesn't really work for management teams," Dimon told The Economist in an interview that aired in July 2023.

To be sure, Google has been easing away from a 100% remote work arrangement for employees since 2022.
Google employees are currently working on a hybrid model where they spend "approximately three days in the office and two days wherever they work best—whether that's at the office or at home," per the company's 2022 Diversity Annual Report .
Google also began tracking office badge attendance and using it as a metric in performance reviews, CNBC reported in June 2023, citing internal memos it had seen.
"Of course, not everyone believes in 'magical hallway conversations,' but there's no question that working together in the same room makes a positive difference," Google's chief people office, Fiona Cicconi, wrote in an employee email obtained by CNBC.
