How do I use Yandex SpeechKit?

The service runs via the HTTP API. You can find instructions for using the service in the documentation and either start using the service yourself or contact us. We’ll help you find a partner that will develop a solution specifically for your project.

Why should I register in the Yandex Cloud console?

To use the API, you need to get an ID (an IAM token or API key). This ID is linked to your account in Yandex Cloud.

What is a recognition model?
