Hello. Technologies develop very quickly, and it is very pleasant that not only abroad.
The company Yandex presented its development, namely a multiplatform library, which gives developers access to their own speech recognition technology, SpeechKit.
More information further ...
This library only works on Android and iOS platforms. While she is able to “understand” only the Russian language, there is much to develop!
As for the quality of recognition, it is:
- 84% for general requests made by Internet users;
- 94% for geographic queries.


In its work, Yandex SpeechKit relies on acoustic and language models, for which Yandex needed to record and mark 300 hours of male, female and children's speech. Language models were formed based on search queries and specially prepared texts.
The recognition speed of a voice search query is approximately 1 second.
One of the
conditions for using the service is the following: Yandex SpeechKit can be used free of charge if the number of requests does not exceed 10,000 per day.

Of course, Yandex is not alone in this matter. Other companies have their technologies. For example, Google Android Speech API from Google, which, however, only works on Android, and some others.
