Open-source EOU model for English + 8 Indic languages stops voice agents cutting callers off
martian7r · reddit · 2026-11-09
A developer released an end-of-turn (EOU) detector fine-tuned from Qwen2.5-0.5B that scores live transcripts to predict whether a caller finished speaking — fixing Indic-language voice agents that interrupt because verb-final syntax makes mid-sentence pauses sound complete to VAD. Covers English, Hinglish, Hindi + 6 more Indic languages; CPU-only ONNX (2GB, fp32, fully local); drop-in for LiveKit Agents' text turn detector; 91.3% TPR at 10% false cuts (AUC 0.967), 85.3% on LiveKit's Hindi real-speech harness. Apache-2.0 on Hugging Face.
