Automatic speech recognition for mobile applications in Yandex
This talk describes the work developed by the Yandex Speech Group in the last two years. Beginning from scratch, large amounts of voice recordings were collected from the field of application, and the most popular open source speech projects were studied to get a thorough understanding of the problem and to gather ideas to build our own technology. This talk will present key experiments and their results, as well as our latest achievements in automatic speech recognition in Russian. Currently, the Yandex Speech Group provides three different services in Russian: maps, navigation, and general search, with a performance that is comparable to competitor products.
