# Groq Whisper API (free)

Transcribe audio files using Groq's free Whisper inference API.

## Quick start

```bash
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a
```

Defaults:
- Model: `whisper-large-v3` (Groq's fastest whisper model)
- Output: `<input>.txt`

## Useful flags

```bash
{baseDir}/scripts/transcribe.sh /path/to/audio.ogg --model whisper-large-v3 --out /tmp/transcript.txt
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a --language en
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a --prompt "Speaker names: Peter, Daniel"
{baseDir}/scripts/transcribe.sh /path/to/audio.m4a --json --out /tmp/transcript.json
```

## API key

Uses the `GROQ_API_KEY` environment variable (already configured on the gateway).

## Models available

- `whisper-large-v3` - Latest and fastest on Groq (recommended)
- `whisper-large-v2` - Slightly older but still fast
- `whisper-base` - Faster but less accurate
