Claims

C1strongest claim

We introduce Voice of India, a closed source benchmark built from unscripted telephonic conversations covering 15 major Indian languages across 139 regional clusters. The dataset contains 306230 utterances, totaling 536 hours of speech from 36691 speakers with transcripts accounting for spelling variations.

C2weakest assumption

That the unscripted telephonic conversations and manually created transcripts with spelling variants provide a meaningfully superior and unbiased representation of real-world Indic speech compared to existing scripted benchmarks.

C3one line summary

Voice of India is a new 536-hour benchmark of real telephonic conversations in 15 Indian languages with variant-aware transcripts for more realistic ASR evaluation.
