Where the two meet
WER on Indian languages is dominated by dialect and code-mixing failures that generic corpora do not cover That is a tts voice building problem, and it is solved by data shaped like this:
- 10-40 hours from one speaker, or multi-speaker sets
- Phonetically balanced scripts
- Session-consistent acoustics
Your evaluation criteria
- Are train/dev/test splits speaker-disjoint by construction?
- Is transcription verbatim, with disfluencies preserved?
- Is per-token language ID available for code-mixed speech?
- Is inter-annotator agreement measured and reported?

Metrics
- MOS naturalness
- Pronunciation accuracy on loanwords and names
- Prosody stability across long utterances
Pitfalls
- Session drift between recording days
- Scripts that under-cover rare phonemes
- Uncleared voice-talent licensing
Contract points
- Speaker-disjoint splits guaranteed contractually
- Right to publish benchmark results
- Re-record remedy for QA failures
