Build with one API

Read the docs
Streaming, two ways
Chunked audio over plain HTTP, or a live websocket that speaks while your LLM is still writing.
OpenAI-compatible
The speech endpoint answers the OpenAI SDK at /v1/audio/speech. Swap the base URL and nothing else.
Timed speech
Ask for timestamps and speech returns word, sentence, or utterance spans for captions and read-along interfaces.
Usage-based billing
Speech at 10 credits per 1,000 characters, transcription at 8.33 credits per minute of audio, OCR at 6.5 credits per page, and translation at 25 credits per 1,000 characters, counted per request. Failed requests are refunded automatically.

Timestamps

Enterprise

Realtime speech, on capacity reserved for your workload.

Milliseconds to first audio
15-20
Faster than real time
190-300×

For voice agents, live dubbing, and anything a person is waiting on. Volume, rate limits, and concurrency are quoted to the workload you run. Both figures are the best results from our own load test on dedicated hardware, and the self-serve plans run on shared capacity.
