Vosk Review

What we know about Vosk

This is our verified profile of Vosk, a speech-to-text apis platform - lightweight offline STT toolkit for edge and embedded devices. Every fact about Vosk below carries the source it came from and the day we checked it.

Vosk does not publish a public per-minute rate we have been able to verify, so the price figure here stays blank until we can confirm one. We would rather show nothing than a guessed number; if you have a current Vosk quote, it is the fastest way for us to close that gap.

On capabilities, Vosk covers word-level timestamps, custom vocabulary / keyterm boosting, self-host / on-prem option, and websocket streaming api. Each of those is verified against Vosk's own docs or dashboard, not marketing copy.

Vosk ranks the 34th-widest language coverage of the 43 speech-to-text tools we track, so where it lands for you depends on which of those matters more.

In total we track 12 verified facts for Vosk today, each linking the primary source it came from so you can check our work - and vendor claims we have not measured ourselves are labeled as such on the Vosk fact sheet below.
