Why enterprises choose Speechmatics over Gladia
Why enterprises choose Speechmatics over Gladia
Accuracy on the audio that actually matters
Your users don’t speak in quiet studios. Speechmatics’ Ursa 2 model is trained on over one million hours of noisy, accented, real-world audio — and it shows. G2 reviewers score Speechmatics 94% for noise adaptation and 84% for speaker identification vs Gladia’s 75%. When your pipeline hits Scottish accents over a bad VoIP line, that gap matters.
Real-time diarisation, included
Speechmatics delivers best-in-class real-time speaker diarisation at no extra charge. Gladia does not offer speaker diarisation in real-time streaming — only in batch mode. If you’re building voice agents or live call analytics, you need to know who is speaking now, not after the call ends.
On-prem, on-device, air-gapped
Speechmatics offers mature on-premises, on-device, and air-gapped deployment. Gladia’s on-premises offering is currently paused, with no on-device or air-gapped options — limiting choices for regulated industries.
