Yandex.Conversation is a mobile application designed to assist deaf and hard-of-hearing individuals in communicating with others by converting spoken language into text and vice versa. The app captures spoken words and displays them as text on the smartphone screen, allowing users to engage in conversations more effectively. For optimal performance, users are encouraged to speak slowly and clearly, utilizing simple phrases.

The application also features a text-to-speech function, enabling users to type their responses, which the app can then vocalize or display on the screen for the other party. Additionally, Yandex.Conversation offers pre-written phrases for common scenarios, such as starting a conversation or asking for help. It records all exchanges in a dialogue format, allowing users to revisit and continue conversations. Currently, the app supports communication in Russian, with limitations on the number of participants and requires a stable internet connection in quieter environments.
