OpenAI launches TTS API: six voices, streaming and aggressive pricing
In one sentence OpenAI launches its TTS API with 6 voices, pricing at $0.015 per 1000 characters, low latency streaming, and direct integration into the ChatGPT and Assistants ecosystem.
OpenAI doesn't stop at text models and announces its first public TTS API, bringing voice synthesis directly into the platform that millions of developers already use for GPT-4 and Assistants.
Six different voices — Alloy, Echo, Fable, Onyx, Nova, Shimmer — cover styles from neutral to expressive. The price per 1000 characters is competitive with major competitors and streaming support allows starting to hear audio while it's still being generated, reducing perceived latency.
Native integration with the OpenAI ecosystem means developers already accustomed to ChatGPT APIs can add voice to their applications in a few lines of code.
