Speech Synthesis & Recognition

Bailian CLI command reference for speech synthesis (TTS), speech recognition (ASR), and hot-word vocabulary management.

A single command invokes Bailian's speech synthesis and recognition capabilities from the terminal, with hot-word vocabulary management for improved accuracy.
Append --help to any command for full parameter details, e.g. bl speech synthesize --help. Every parameter that accepts a file URL also accepts a local path — the CLI auto-uploads it to temporary storage (valid for 48 hours), so you never need to host files as URLs yourself.
