OpenAI Text to Speech API

OpenAI's GPT-4o audio models on one API. For text to speech, GPT-4o Mini is the low-latency option and GPT-4o Mini HD trades speed for cleaner audio at twice the price — six voices and six output containers on both, with speed control from a quarter to four times normal. In the other direction, GPT-4o Transcribe converts speech to text with high accuracy.

You can ask OpenAI Text to Speech to handle text-to-speech / voice synthesis. Powered by OpenAI via the Pixazo API gateway.
