Overview
Description
Silero VAD reliably detects when a person is speaking in any audio stream or recording — a critical building block for voice bots, call center automation, and voice-enabled products. It works across 6,000+ languages and runs efficiently on standard CPUs with no cloud dependency, no API keys, and no recurring fees. The bottom line: add accurate voice activity detection to your product in minutes with zero vendor lock-in.
