silero

Silero provides ultra-lightweight, enterprise-grade pre-trained models for speech-to-text, text-to-speech, and voice activity detection that run locally on a single CPU thread.

Silero delivers high-performance speech processing without the heavy infrastructure requirements of traditional deep learning pipelines. Its flagship offerings include a highly accurate Voice Activity Detector (VAD) that processes a 30-millisecond audio chunk in under 1 millisecond on a single CPU thread, alongside robust Text-to-Speech (TTS) and Speech-to-Text (STT) models. By packaging these models into compact PyTorch and ONNX formats, Silero enables developers to deploy production-ready voice features directly on edge devices, in web browsers, or on low-power servers with zero external API dependencies.
