Adding New TTS Providers

The skill uses an extensible provider architecture. To add a new provider:

  1. Create provider class in 
    scripts/<provider>_provider.py
    :
from tts_provider import TTSProvider

class NewProvider(TTSProvider):
    @property
    def name(self) -> str:
        return "new-provider"

    @property
    def supported_voices(self) -> List[str]:
        return ["voice1", "voice2"]

    # Implement other required methods...
  1. Register provider in 
    scripts/provider_registry.py
    :
from new_provider import NewProvider
ProviderRegistry.register(NewProvider)
  1. Use immediately:
scripts/create_audio.py --provider new-provider --voice voice1 --text "Test"

See 

scripts/pocket_tts_provider.py
for a complete implementation example.

Advanced Usage

Provider-Specific Parameters

Pass provider-specific parameters as JSON:

scripts/create_audio.py \
  --voice custom \
  --params '{"custom_voice_path": "/path/to/voice.wav"}' \
  --text "Using custom voice" \
  --output result.wav

Batch Processing

Generate multiple audio files:

# Simple loop
for voice in alba marius jean; do
  scripts/create_audio.py \
    --voice $voice \
    --text "Sample text" \
    --output "${voice}_sample.wav"
done

Installation Requirements

Pocket TTS

# Via pip
pip install pocket-tts

# Or use uvx (no installation needed)
uvx pocket-tts generate --text "Test"

Dependencies:

  • Python 3.10+ (supports up to 3.14)
  • PyTorch 2.5+ (CPU version)
  • scipy (for WAV file writing)

Troubleshooting

Model not loading?

  • First run takes longer (downloads model)
  • Model is cached for subsequent uses
  • Check internet connection for initial download

Import errors?

pip install pocket-tts scipy

Voice file not found?

  • Ensure WAV files are valid audio files
  • Use absolute paths for custom voices
  • Check file permissions
