Install from source with git clone and pip install -e ., then run voice-recorder-mcp with optional --model and --sample-rate arguments. Configure via environment variables like WHISPER_MODEL, SAMPLE_RATE, and MAX_DURATION. Use the tools start_recording, stop_and_transcribe, and record_and_transcribe to manage recordings.

Frequently asked questions

1

What Whisper models can I use?

The server supports tiny.en, base.en, small.en, medium.en, and large. Models with a `.en` suffix are optimized for English, offering faster and more accurate transcription.

2

How do I integrate with Goose?

In Goose, go to Settings > Extensions > Add > Command Line Extension, set the name to `voice-recorder`, and provide the full path to the `voice-recorder-mcp` executable.

3

What are the system requirements?

Python 3.12 or later and an audio input device (microphone).

4

How can I adjust recording quality?

Set the sample rate via the `--sample-rate` command-line argument or the `SAMPLE_RATE` environment variable (default 16000). Use higher sample rates for better audio quality, though file sizes increase.

5

What if no audio is recorded?

Check your microphone permissions and settings. Also ensure the server has access to the audio device. If model download fails, verify your internet connection.
