Fish Audio Transcribe 1 Pro
Fish Audio's speech-to-text model for multi-speaker conversations, which labels who is speaking and keeps emotion and vocal-event cues such as laughter in the transcript.
Transcribe 1 Pro is a cloud speech-to-text model built by Fish Audio. It transcribes spoken audio into written text. It handles multiple spoken languages and can return timestamped segments along with the transcript. It runs through Fish Audio and OpenRouter using your own API key, from about $0.006 per minute of audio.

Samples
Transcribed by Transcribe 1 Pro via OpenRouter. The same three clips go to every speech-to-text model in the catalog, so the only thing that changes between two models’ transcripts is the model. The clips are synthetic speech made with ElevenLabs v4, and a word that differs from the spoken script is underlined. The numbers clip is left unmarked, since “12” and “twelve” are both right.
