OpenAI Whisper Base
A small on-device Whisper model that transcribes speech in the app with no API key, trading accuracy for speed.
Whisper Base is an open-weight speech-to-text model built by OpenAI. It transcribes spoken audio into written text. It handles multiple spoken languages and can return timestamped segments along with the transcript. It runs entirely on your own hardware through Hugging Face: no API key and no per-use fees.

Samples
Transcribed by Whisper Base via Hugging Face. 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.
Baseline accuracy and punctuation on clean speech
