Convert message text to audible speech in 7 different languages
Text to Speech from IBM Watson provides an API for converting message text to audible speech, for a wide variety of languages and voices, and customizable cadence, emotion, and tone.
The IBM Watson Text to Speech block converts text in your real-time data streams, and converts that input text to natural-sounding speech. For example, a chat app could process messages in one language, and output them verbally, in a different language.
Walkthrough
