语音转文字（设备端）

使用设备端 Whisper 模型将文件或麦克风中的语音转成文字。音频不会离开您的设备；模型在首次使用时下载。

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.

使用方法

Choose a model (Tiny is fast, Base is better) and the audio language.
Pick an audio file, or record from the microphone.
Press Transcribe. The first run downloads the model.

注意事项

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.

常见问题

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.
