Usage

omnisense transcribe [OPTIONS] AUDIO_PATH

Key Options:

• --language: Automatically detect the language or specify (auto, zh, en, yue, ja, ko).
• --textnorm: Choose whether to apply inverse text normalization (withitn for inverse normalized or woitn for raw).
• --device-id: Run on a specific GPU (default: -1 for CPU).
• --quantize: Use a quantized model for faster processing.
• --help: Display detailed help information.
