Duo Interpreter

Speak across languages with Duo Interpreter. Choose what you speak and what the other person speaks, then follow the conversation with paired original text and translations. • Real-time, two-way interpreting across 24 languages, plus a Cantonese–Mandarin pair. Some language directions provide subtitles only. • Optional translated speech resembling the current speaker's voice, or a standard voice. • Buy interpreting time through Google Play without registering a separate login, or use your own Alibaba Cloud API key. • In own-key mode, Chinese–English is included; a one-time All Languages purchase unlocks the other supported pairs. Alibaba Cloud usage fees are separate. • Keep interpreting while switching apps or locking your phone. An Android microphone notification provides a Stop control. • Save, delete and export conversation records locally. An internet connection is required. With your permission, speech and conversation text are processed by Alibaba Cloud. You can decline or withdraw AI data-sharing consent in Settings. Purchased time is counted while connected. Voice interpreting uses time at 1:1; subtitles use one third as much. Each start charges the first minute at the selected rate. Interpreting stops after five minutes without speech. Save your Android time-account recovery code before reinstalling or changing phones. Google Play restores the language pack; time-account recovery is separate. iOS and Android balances are not automatically combined.
