    Production studios can recognize text from the audio of live streams and display the recognized text as subtitles in real time. The recognized text can be translated in real time. The displayed subtitles can be the recognized text, the translations, or bilingual subtitles.

    Production studios support translation to and from the following languages: Chinese, English, Spanish, and Russian. Real-time subtitles enhance the effect of the content and facilitate the understanding for the audience who find it inconvenient to listen to the audio. Real-time translation helps the audience who use different languages or are from different countries to understand the live streams in foreign languages. This feature is applied in live streaming scenarios of cross-border e-commerce and cross-border events.
