![]() ![]() ![]() These samples cover text to speech conversion in most popular programming languages: Sample code for text to speech is available on GitHub. To convert text to speech with a no-code approach, try the Audio Content Creation tool in Speech Studio. Viseme is currently supported only for the en-US (US English) neural voices. This data can be used to animate faces in lip-reading communication, education, entertainment, and customer service. Visemes have a strong correlation with voices and phonemes.īy using viseme events in Speech SDK, you can generate facial animation data. Visemes: Visemes are the key poses in observed speech, including the position of the lips, jaw, and tongue in producing a particular phoneme. To fine-tune the voice output for your scenario, see Improve synthesis with Speech Synthesis Markup Language and Speech synthesis with the Audio Content Creation tool. With the multilingual voices, you can also adjust the speaking languages via SSML. You can use SSML to define your own lexicons or switch to different speaking styles. With SSML, you can adjust pitch, add pauses, improve pronunciation, change speaking rate, adjust volume, and attribute multiple voices to a single document. Convert digital texts such as e-books into audiobooks.įor a full list of platform neural voices, see Language and voice support for the Speech service.įine-tuning text to speech output with SSML: Speech Synthesis Markup Language (SSML) is an XML-based markup language that's used to customize text to speech outputs.Make interactions with chatbots and voice assistants more natural and engaging.Each prebuilt neural voice model is available at 24kHz and high-fidelity 48kHz. Prosody prediction and voice synthesis happen simultaneously, which results in more fluid and natural-sounding outputs. Prebuilt neural voices: Microsoft neural text to speech capability uses deep neural networks to overcome the limits of traditional speech synthesis with regard to stress and intonation in spoken language. ![]() The expectation is that requests are sent asynchronously, responses are polled for, and synthesized audio is downloaded when the service makes it available. Unlike synthesis performed via the Speech SDK or Speech to text REST API, responses aren't returned in real-time. Real-time speech synthesis: Use the Speech SDK or REST API to convert text to speech by using prebuilt neural voices or custom neural voices.Īsynchronous synthesis of long audio: Use the batch synthesis API (Preview) to asynchronously synthesize text to speech files longer than 10 minutes (for example, audio books or lectures). Here's more information about neural text to speech features in the Speech service, and how they overcome the limits of traditional text to speech systems: That can result in muffled, buzzy voice synthesis. Traditional text to speech systems break down prosody into separate linguistic analysis and acoustic prediction steps that are governed by independent models. The patterns of stress and intonation in spoken language are called prosody. With the clear articulation of words, neural text to speech significantly reduces listening fatigue when users interact with AI systems. This engine uses deep neural networks to make the voices of computers nearly indistinguishable from the recordings of people. The text to speech feature of the Speech service on Azure has been fully upgraded to the neural text to speech engine. More about neural text to speech features After you've been granted access, visit the Speech Studio portal and select Custom Voice to get started. Create an Azure account and Speech service subscription (with the S0 tier), and apply to use the custom neural feature. Check the pricing details.Ĭheck the the Voice Gallery and determine the right voice for your business needs.Ĭustom Neural Voice (called Custom Neural on the pricing page)Įasy-to-use self-service for creating a natural brand voice, with limited access for responsible use. Create an Azure account and Speech service subscription, and then use the Speech SDK or visit the Speech Studio portal and select prebuilt neural voices to get started. Prebuilt neural voice (called Neural on the pricing page) Text to speech includes the following features: Feature For a full list of supported voices, languages, and locales, see Language and voice support for the Speech service. Use humanlike prebuilt neural voices out of the box, or create a custom neural voice that's unique to your product or brand. The text to speech capability is also known as speech synthesis. ![]() Text to speech enables your applications, tools, or devices to convert text into humanlike synthesized speech. In this overview, you learn about the benefits and capabilities of the text to speech feature of the Speech service, which is part of Azure Cognitive Services. ![]()
