Listeners simply choose the receiver channel assigned to their group.
Two-Way Group Translation

FAQ
Q: Does TT136 need internet to work?
A: AI translation requires internet (Wi-Fi/hotspot). Original one-to-many guide mode works without internet.
Q: Can one transmitter support the original audio plus two translated languages?
A: For translated output, it currently supports up to 2 target languages at the same time. For speaker language recognition, TT136 can recognize up to 10 spoken languages in one session. The technology is continuously being updated.
Q: How are translation credits calculated?
A: Each TT136 includes 100 hours of factory-provided translation time. Each second of AI translation consumes 2 translation credits, and credits are deducted based on actual translation duration once the translation function is activated. If more translation credits are needed, additional packages can be purchased.
Q: If no translation is used, are credits still consumed?
A: No. Translation usage starts only when the AI translation function is activated. If you use TT136 only for original audio transmission, no translation credits are consumed.
Q: Does TT136 support real-time AI translation?
A: Yes. It uses AI speech recognition and online translation engines (Microsoft and Google) to provide real-time translation in up to 120 languages.
Q: How accurate is dialect translation?
A: The device is equipped with a dual translation system. The main standard-language translation system provides an accuracy rate of over 85%. For dialects and regional accents, users can switch to the dedicated backup translation system, which improves translation accuracy up to 97% (excluding classical poetry).
Q: Will translation delay be greatly affected by the network connection?
A: Translation response speed is slightly affected by the network. The delay is consistently controlled between 80-400 ms, and users can adjust the translation interval according to their needs.
Q: How do I pair the transmitter and receivers?
A: After power-on, the transmitter and receivers pair automatically within 5 meters. If not, keep the transmitter on and press and hold Volume + and Volume - on the receiver to reconnect.
Q: Can I return the system after testing it?
A: Please check our return policy or contact us before purchase for confirmation on trial use, return conditions, and any related information.
Q: What's the main difference between TT136 and traditional tour guide systems?
A: Traditional systems only transmit the original voice. TT136 adds AI real-time translation, so it can support multilingual group communication.
