Groq Whisper

Transcribe audio files using Groq's Whisper API (whisper-large-v3). Fast cloud-based speech-to-text with no local model required. Use when receiving voice messages, audio files, or any speech that needs transcription. Supports all major audio formats (ogg, mp3, wav, m4a, webm, flac).

Cloud speech-to-text via Groq's Whisper API. No local model, no GPU, no fan spin.

Setup

1. Get a free API key at console.groq.com
2. Store it:

   mkdir -p ~/.config/groq
   echo '{"api_key":"gsk_your_key_here"}' > ~/.config/groq/credentials.json
   chmod 600 ~/.config/groq/credentials.json
   

   Or set GROQ_API_KEY env var.

Usage

# Transcribe an audio file
{baseDir}/scripts/transcribe.sh /path/to/audio.ogg

# Specify language (default: en)
{baseDir}/scripts/transcribe.sh /path/to/audio.ogg es

When to use

Call this script whenever you receive an audio/voice message attachment. Pass the file path directly — Groq handles ogg, mp3, wav, m4a, webm, and flac natively. No format conversion needed.
