Speak human, not robot
Build apps and services that speak to users naturally, improving accessibility and usability. Convert text to audio in near real time, play it back, and save it as a file for later use. Text to Speech is available in both Neural and Standard versions.
Applying the latest in digital speech innovation, the Neural Text to Speech capability makes the voices of your apps nearly indistinguishable from recordings of people. The natural inflection and clear articulation significantly reduce listening fatigue when interacting with AI systems. Use Neural Text to Speech to make interactions with chatbots and virtual assistants more natural and engaging, to convert digital text such as e-books into audiobooks, and to enhance in-car navigation systems.

Explore a Speech Scenario
Speech services combined with Language Understanding enables apps and users to interact naturally. Use Speech to Text to capture a user’s question, Language Understanding to parse intent and formulate an appropriate reply, and Text to Speech to synthesize the text into a spoken response. Create conversational interfaces for various scenarios like banking, travel, and entertainment.
Together, the Azure Bot Service and Language Understanding service enable developers to create conversational interfaces for various scenarios like banking, travel, and entertainment. For example, a hotel’s concierge can use a bot to enhance traditional e-mail and phone call interactions by validating a customer via Azure Active Directory and using Cognitive Services to better contextually process customer requests using text and voice. The Speech recognition service can be added to support voice commands.
- 1 Customer uses your mobile app
- 2 Using Azure AD B2C, the user authenticates

- 4 Cognitive Services helps process the natural language request
- 5 Response is reviewed by customer who can refine the question using natural conversation
- 6 Once the user is happy with the results, the Application Bot updates the customer’s reservation
- 7 Application insights gathers runtime telemetry to help development with Bot performance and usage
