FAQ
Q: What is the warranty policy for the TT136 AI Multilingual Communication System?
A: Support a 30-day no-reason return policy and a 3-year warranty. During the warranty period, free repair or replacement service is provided for quality-related issues.
Q: What’s the main difference between TT136 and traditional tour guide systems?
A: Traditional systems only transmit original voice audio. The TT136 automatic multilingual translation device integrates AI real-time translation with one-to-many audio broadcasting, allowing cross-language group communication that traditional systems cannot do.
Q: Does TT136 support real-time AI translation?
A: Yes. It uses AI speech recognition and online translation engines (Microsoft & Google) to provide real-time translation in up to 120 languages.
Q: How many languages can TT136 support at the same time?
A: A single transmitter can broadcast a maximum of 2 target languages simultaneously. To support 3 different languages at once, you will need 2 transmitters.
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 80-400ms, and users can adjust the translation interval according to their needs.
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: Does TT136 need internet to work?
A: The AI translation function requires a network (Wi‑Fi/hotspot). When used only as a traditional audio guide, it works without any internet connection.
Q: How do I use the translation function?
A: To use the translation function on the transmitter, an internet connection is required first. Translation time must then be activated by contacting the seller and providing the device's internal code for recharge.
Q: How do I pair the transmitter and receivers?
A: After powering on, the transmitter and receivers will automatically search for and connect to each other within a 5-meter pairing range.
If no signal is detected, keep the transmitter powered on, then press and hold the receiver's Volume + and Volume - buttons simultaneously to search for nearby transmitters and complete pairing.
Q: What scenarios is TT136 suitable for?
A: It is widely used in tourism, factory tours, international conferences, exhibitions, corporate training, multilingual education, and other group communication occasions.
