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

Multiple validation models for Indian language transcriptions:
- IndicMFA: Montreal Forced Aligner with Indic acoustic models (forced alignment)
- Vistaar: AI4Bharat's IndicWhisper-based ASR
- IndicConformer: AI4Bharat's Conformer ASR model (requires HF access)

Each validator can be toggled independently for flexible validation pipelines.

Note: IndicWav2Vec removed due to fairseq version incompatibility with AI4Bharat models.

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

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

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