Context

OpenRouter offers AssemblyAI's Universal-3.6 Pro through a synchronous transcription interface: submit a WAV audio clip of up to 120 seconds and receive a complete transcript with word timestamps in one response. The model listing makes this short-clip workflow explicit.

The listed base price is approximately $0.30 per audio hour; prompted requests have a higher rate. Prompts, keyterms and conversation can steer transcription toward relevant vocabulary. This gives applications a way to supply domain context when transcribing a clip.
