Sanas vs Krisp: Verified Facts about Accent Translation & Noise Cancellation Performance

Accent Translation

Sanas thrives on competition, but only when it’s honest. Recently, Krisp has made claims that distort the facts about our technology, performance, and reach. Despite repeated requests for Krisp to remove the article, it remains online. We won’t let misinformation stand unchallenged.

The data speaks for itself: Sanas pioneered real-time speech understanding, and our results continue to set the global standard. The following comparison presents information on Krisp’s claims about Krisp capabilities and false and misleading claims about Sanas taken from a Krisp blog dated April 21, 2025, alongside the facts about Sanas as of October 2025, verified by live deployments and measurable outcomes.
