## Summary

Sarvam AI released Saaras V4, a speech-to-text model supporting all 22 scheduled Indian languages plus global English accents. The encoder-decoder system uses a 3B-parameter hybrid state-space language model (Sarvam-3B) trained in-house to process audio embeddings into transcripts. It claims state-of-the-art accuracy across languages, including noisy audio, with vendor-reported benchmarks showing lower word error rates (WER) than competitors like Deepgram Nova-3 and GPT-4o Transcribe in some cases.

Key features include five output modes (transcription, verbatim, codemix, transliteration, and translation), keyterm prompting (up to 50 terms), and streaming capabilities with sub-150ms time-to-first-token. Pricing starts at ₹30 per hour for real-time transcription, with optional diarization at ₹45/hour. The model is available via Sarvam’s API today, though self-hosting documentation still references Saaras v3. No independent validation of the benchmarks has been published yet.

## Key points

- Saaras V4 supports 22 Indian languages and global English accents in one model, with vendor-reported state-of-the-art accuracy
- Keyterm prompting allows up to 50 terms to bias transcription, and five output modes let users choose transcription style
- API pricing is ₹30/hour for real-time transcription, with streaming support and sub-150ms latency

## Why it matters

This model fills a critical gap for multilingual speech recognition in India, where English and regional languages coexist. Its low-latency streaming and multi-mode outputs could simplify workflows for call centers, media, and accessibility tools, though vendor claims await independent verification.
