TT136 combines real-time AI translation and one-to-many audio guiding in one portable system for tours, conferences, factory visits, churches, and international teams.
It supports 120+ online languages to help reduce communication barriers and improve multilingual group communication efficiency.
For many scenarios, it can reduce dependence on traditional interpretation setups while making multilingual listening easier and more flexible.
TT136 supports real-time one-way and two-way translation for more flexible communication in meetings, visits, and guided group activities.
Speakers can preset up to 2 target languages for simultaneous broadcast, while listeners can freely switch between language channels based on their needs.

TT136 works without requiring users to download extra software, making deployment easier for event organizers and group users.
Translation credits are only consumed when the AI translation function is activated, so original audio transmission does not use translation time.
Pricing is transparent and usage-based, allowing you to scale translation services according to your actual needs.
Optional 30-slot and 50-slot charging boxes help simplify charging, storage, and device management for group deployments.

In this mode, one speaker's speech can be translated into one/two target languages in real time without extra guides or interpreters. Fast, accurate, and low-delay, one-to-many translation makes cross-language communication simple.

During the same session, TT136 can handle speech from participants using up to 10 spoken languages and translate the content into two target languages. Listeners simply choose the receiver channel assigned to their group.

TT136 helps two language groups follow the same tour, explanation, or discussion more easily. The current speaker uses the transmitter while different groups wear different receivers. Each group listens to its assigned language channel. Ideal for guided tours, group Q&A, meetings, and bilingual presentations.

When translation isn't needed, the device works as a professional one-way guide system. The speaker's voice is sent directly to all receivers in real time, delivering clear, immersive sound for tours, factory visits, schools, and training. This function works without internet access.

Supports recording, playback, local storage, and AI summary. Stored recordings and voice content can be replayed locally, helping with repeated training, self-guided use, and content review.

Lightweight, open-ear receivers are non-intrusive, hygienic, and comfortable for long-time use. The ear hook fits either ear, making them perfect for public and repeated use.

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.
