FAQ
Q: Does TT136 need internet to work?
A: AI translation requires internet access, such as Wi-Fi or a mobile hotspot. The original one-to-many tour guide mode works without internet.
Q: Can one transmitter support the original audio plus two translated languages?
A: For translated output, TT136 currently supports up to 2 target languages at the same time. For speaker language recognition, it 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 you need more translation credits, additional packages can be purchased.
Q: If no translation is used, are credits still consumed?
A: No. Translation credits are only used 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, including Microsoft and Google, to provide real-time translation in up to 120 languages.
Q: How accurate is dialect translation?
A: TT136 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 can improve 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 connection. The delay is generally controlled between 80 and 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 they do not pair automatically, 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 to confirm trial use, return conditions, and related details.
Q: What's the main difference between TT136 and traditional tour guide systems?
A: Traditional tour guide systems only transmit the original voice. TT136 adds AI real-time translation, making it suitable for multilingual group communication.
Q: Can TT136 be used without AI translation?
A: Yes. TT136 can also be used as a regular one-to-many wireless tour guide system when AI translation is not activated. In this mode, it transmits the speaker’s original voice and does not consume translation credits.
Q: What applications is TT136 best suited for?
A: TT136 is ideal for multilingual tours, international training, factory visits, church translation, business reception, exhibitions, and other group communication scenarios where both original audio transmission and real-time AI translation may be needed.
