About Google Cloud Text-to-Speech

Pick a voice family by use case; bill in JPY and run Chirp 3 HD in Tokyo.

Google Cloud Text-to-Speech is an API where you choose a family of voices to match the job. Chirp 3 HD is for conversational agents and supports streaming, Studio is for narration, Neural2 and WaveNet are general-purpose, Standard is the low-cost option, and Studio multispeaker (Experimental) handles two-person dialogue. Gemini-TTS is also available when you want to describe the delivery in text. It is called through REST, gRPC or client libraries, so it suits developers and teams already on Google Cloud.

Characteristics

  • Voice families by use (Chirp 3 HD, Studio, Neural2, WaveNet, Standard)
  • Gemini-TTS takes written instructions for accent, tone and emotion
  • Chirp 3 HD supports pace, pauses, phonetic pronunciation and streaming
  • Available through REST, gRPC and client libraries
