Yandex SpeechKit is one of the services offered by Yandex Cloud. The service infrastructure is designed with high loads in mind to ensure that the system is available and fault-free even if the number of concurrent requests is high. SpeechKit is the power behind Alice, the Yandex voice assistant.


The connection to the globally accessible services is maintained via gRPC, which ensures secure, reliable and fast transmission of data over the Internet.

For installation, configuration and usage instructions, consult the guides available on a new Yandex SR plugin page.


Please note this is a commercial module. Everyone is welcome to start evaluation by requesting a trial license. The production license is priced at $50 per channel.
