Add a new `validate` subcommand that checks JSONL training manifests
before starting expensive fine-tuning jobs. This catches format issues,
missing audio files, and data quality problems early.
The validator performs:
- JSONL format validation (each line must be valid JSON)
- Required column checks (text, audio)
- Audio file existence and readability verification
- Duration and text length statistics (min, max, mean, median)
- Optional ref_audio column validation
- Warnings for very short (<0.3s) or very long (>30s) audio samples
Usage:
voxcpm validate --manifest train.jsonl
voxcpm validate --manifest train.jsonl --sample-rate 16000 --verbose
The module uses lazy imports for soundfile, so it works even in
minimal environments. Includes 11 unit tests covering all validation
paths.
Support optional ref_audio samples in finetuning and make runtime device selection explicit while keeping auto fallback behavior consistent. Also ignore the local app override file to avoid accidental commits.
