### Run long-form inference with automatic text chunking

Source: https://github.com/supertone-oss-archive/supertonic/blob/main/swift/README.md

Automatically splits long texts into chunks, synthesizes each separately, and concatenates with 0.3-second pauses. This happens by default when not using --batch. Note: chunking is disabled in batch mode.

```bash
.build/release/example_onnx \
  --voice-style ../assets/voice_styles/M1.json \
  --text "This is a very long text that will be automatically split into multiple chunks. The system will process each chunk separately and then concatenate them together with natural pauses between segments. This ensures that even very long texts can be processed efficiently while maintaining natural speech flow and avoiding memory issues."
```

### Adjust speech speed

Source: https://github.com/supertone-oss-archive/supertonic/blob/main/py/README.md

Controls speech speed with --speed. Values >1.0 produce faster speech, <1.0 slower. Default is 1.05; recommended range is 0.9 to 1.5.

```bash
# Faster speech (speed > 1.0)
uv run example_onnx.py \
  --voice-style ../assets/voice_styles/F2.json \
  --text "This text will be synthesized at a faster pace." \
  --speed 1.2

# Slower speech (speed < 1.0)
uv run example_onnx.py \
  --voice-style ../assets/voice_styles/M2.json \
  --text "This text will be synthesized at a slower, more deliberate pace." \
  --speed 0.9
```
