Bug Fix: Generation Button Not Working

Issues Fixed:

1. Added robust output format handling (audio/data field detection)
2. Enhanced error logging for debugging
3. Added fallback for sample rate detection
4. Improved voice modifier logging

Changes:

• Handle different transformers.js output formats
• Support both output.audio and output.data
• Auto-detect sample rate (default 16kHz if missing)
• Enhanced console logging for troubleshooting
• Better error messages with hints

Technical Details:

// Before:
const wav = encodeWAV(output.audio, output.sampling_rate);

// After:
const audioData = output.audio || output.data || output;
const sampleRate = output.sampling_rate || output.sample_rate || 16000;
const wav = encodeWAV(audioData, sampleRate);

Testing:

• Simplified voice system (20 voices)
• Comprehensive error logging
• Fallback mechanisms for robustness

This should fix the "generate speech button not working" issue.
