Transcription vocale (sur l'appareil)

Transcrivez la parole depuis un fichier ou le microphone avec un modèle Whisper embarqué. L'audio ne quitte jamais votre appareil ; le modèle se télécharge à la première utilisation.

First use downloads the selected Whisper model from Hugging Face (see sizes in the model list). After that, transcription runs entirely on your device: your audio is never uploaded anywhere — only the model files are downloaded.

Pick an audio file, or record from the microphone.
Press Transcribe. The first run downloads the model.

Remarques

Transcription runs a Whisper model on-device with Transformers.js. Your audio is never sent to a server; only the model files are downloaded. Audio is converted to 16 kHz mono in the browser before it reaches the model. Accuracy varies a lot with recording quality, speakers and jargon — treat the output as a draft that needs human review for anything important.

Questions fréquentes

Why is long audio slow?: Inference runs on your device's CPU. Depending on the device, a few minutes of audio can take longer than real time. Choose the Tiny model when speed matters.
Which audio formats work?: Any format your browser can decode (WAV, MP3, M4A, WebM, Ogg, depending on the browser). If decoding fails, an error is shown.
