"""
Voice Bot ASR Comparison Test
Demonstrates the superior accuracy of Groq ASR vs Whisper for voice transcription

Usage:
1. Set your GROQ_API_KEY environment variable
2. Run: python test_groq_asr.py
3. Record some audio to test transcription quality

This shows why your friend's bot works better - Groq ASR is significantly more accurate!
