Silero provides pre-trained enterprise-grade STT models. Enterprise-grade STT made refreshingly simple (seriously, see our benchmarks). We provide quality comparable to Google's STT (and sometimes even better) and we are not Google.

Models < one megabyte in size.
Supports 30, 60 and 100 ms chunks.
