OpenAI TTS Standard

by OpenAI

OpenAI's everyday text-to-speech — six natural voices at the lowest per-character price.

OpenAI TTS Standard is the default voiceover model in Z1 Canvas. It turns a script into natural speech in one of six built-in voices — Alloy, Echo, Fable, Onyx, Nova and Shimmer — across more than 50 languages, at the lowest per-character rate in Canvas.

It is the model for volume: product descriptions read aloud, ad voiceovers to pair with a generated clip, and quick drafts to time a script before committing to the HD model.
