vtt-rs

Command-line utility that streams microphone input to OpenAI compatible transcription APIs

Configuration

• Set OPENAI_API_KEY in your environment before running anything.

• The binary expects an optional JSON configuration file (default vtt.config.json in the current directory, or pass an alternate path as the first argument).

• Supported keys (all optional; sensible defaults exist):

  {
    "chunk_duration_secs": 5,
    "model": "whisper-1",
    "endpoint": "https://api.openai.com/v1/audio/transcriptions",
    "out_file": "transcripts.log"
  }
  

  • chunk_duration_secs: duration of each captured audio block that is transcribed.
  • model: which OpenAI transcription model to hit.
  • endpoint: custom transcription endpoint for e.g. a proxy service.
  • out_file: path to append every transcription (chunk ID + contents).

Running

OPENAI_API_KEY=sk-... cargo run -- vtt.config.json

• Omit the CLI argument to let the tool load vtt.config.json from the current directory if it exists, otherwise it runs with defaults.
• Transcripts are printed live and, when out_file is set, appended to that file in addition to the console output.
