Yandex SpeechKit

Yandex SpeechKit is the speech-recognition and synthesis platform from Yandex, turning Russian audio into text and text into natural voice.

Overview

SpeechKit provides streaming and batch speech recognition, text-to-speech and voice-activity detection through Yandex Cloud, with models that handle Russian, English and several other languages at telephony quality. Developers use it for call analytics, subtitles, voice interfaces and transcription products, and the same technology powers voice features across Yandex’s own services. It scales from hobby projects to national-scale voice workloads.
