Make interactions with chatbots and voice assistants more natural and engaging.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 Long Audio API 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.
