Whisper is the free open-source STT standard — multilingual and self-hostable, though Indian-language specialists can beat it on Hindi.
Best for
- Free, self-hostable, high-accuracy multilingual transcription (99 languages)
- Privacy / offline transcription with full data control
- Batch transcription and subtitling at zero per-minute cost
- Robust to accents and noisy audio
How it compares — and the India angle
- Free and self-hostable — ideal for Indian developers; decent (not best) accuracy on code-mixed Hindi/Hinglish.
- For pure Indian-language STT, Sarvam Saaras often beats Whisper on Hindi/regional accuracy.
- Best free general-purpose STT; pair with Sarvam when Indian-language precision matters.
