Fixed 'dict' object has no attribute 'cpu' error when using Voice Designer
voices with TTS Text node.
## Root Cause
Voice Designer and Character Voices nodes output unified NARRATOR_VOICE format:
{
"audio": {"waveform": tensor, "sample_rate": 24000},
"audio_path": "...",
"reference_text": "...",
...
}
But TTS Text node was wrapping this AGAIN when creating voice_mapping:
{
"waveform": audio_tensor, # audio_tensor was already a dict!
"sample_rate": 24000,
"text": "..."
}
This created triple-nested structure that broke audio hashing.
## Fixes Applied
**TTS Text Node** (nodes/unified/tts_text_node.py):
- Extract actual waveform tensor from audio dict before creating voice_mapping
- Applied to all 6 places where audio_tensor is used:
- Narrator voice mapping (line 1151)
- Character ICL fallback (line 1183)
- Character x_vector fallback (line 1217)
- Character no-text fallback (line 1220)
- Character no-audio fallback (line 1237)
- Pattern: Check if audio_tensor is dict, extract waveform/sample_rate if so
**Qwen3-TTS Adapter** (engines/adapters/qwen3_tts_adapter.py):
- Extract inner audio dict before passing to hash function
- Changed from passing full voice_ref to passing voice_ref['audio']
**Audio Hash Utility** (utils/audio/audio_hash.py):
- Added nested structure handling with fallback
- Detects Character Voices format {"audio": {...}} vs direct format
- Enhanced debug logging to diagnose structure issues
## Testing
- Voice Designer → TTS Text: Works without hash error
- Character Voices → TTS Text: Works without hash error
- Audio hashing generates stable keys for caching
- Both VoiceDesign and traditional voices function correctly
