Validators Module for Transcription Validation
===============================================

Validation models for Indian language transcriptions:
- IndicMFA: Montreal Forced Aligner - aligns reference text with audio timestamps
- IndicConformer: AI4Bharat's 600M Conformer ASR model (22 languages)

Usage:
```python
from src.validators import ValidatorRunner

runner = ValidatorRunner(
    enable_indicmfa=True,
    enable_indic_conformer=True,
    language="te"
)

result = runner.validate(
    audio_path="segment.flac",
    reference_text="reference transcription"
)
```
