OpenAI makes you call sales for a custom voice. Google just made it self-serve.

The New Stack 2 weeks ago 41 ● 9 sources

Google released Gemini 3.8 Flash TTS and Gemini 3.8 Flash-Lite TTS, adding prompt-based voice design plus voice replication via an API Voices endpoint. Google requires two recordings from the same speaker—10 to 30 seconds each—plus a separate consent recording, and returns a voice_id kept in the project for one year. Developers can now create and reuse custom synthetic voices self-serve through the Gemini API and AI Studio instead of relying on a fixed set of voices, while existing prompts with stage directions may break due to changed transcript handling.
