Voz a texto (en el dispositivo)

Transcribe voz desde un archivo o el micrófono con un modelo Whisper en el dispositivo. El audio nunca sale de tu dispositivo; el modelo se descarga en el primer uso.

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.

Notas

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.

Preguntas frecuentes

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.
