About Google Cloud Text-to-Speech
Powered by Google's advanced AI and DeepMind's speech synthesis expertise, the Text-to-Speech API delivers high-fidelity audio. It offers multiple voice types, including standard, WaveNet, and more recent Neural2 voices, for unparalleled clarity and naturalness. Developers can customize speech output by adjusting pitch, speaking rate, volume, and using SSML tags for emphasis and pronunciation. Key use cases include creating voice-driven IVR systems for contact centers, enabling IoT devices with spoken responses, and converting written content like news articles or books into audio.
