Introducing VIVA 2.5, with our most advanced models yet. @krispHQ's Voice Isolation has been running in production for 2 years, across 1B+ mins of voice AI conversations a month, improving WER by focusing on primary speaker only. As more teams ran voice isolation in front of their STT, we started seeing a subtle problem: on the hardest segments with most multi-speaker overlap, the model was removing too much signal which was resulting in WER degradation. Voice Isolation 2.5 fixes that. Across 10 STT engines from 7 vendors we saw: – 46.4% fewer word errors – 69.7% fewer on background speech, the hardest case there is – No harm on clean audio. An important update from previous VI 2.1 model – A 3.5x smaller version, comparable results Full details:
