Remote Simultaneous Interpretation Platform “RSI X”

If you have any concerns regarding the communication quality or security of the online conference system you plan to use, we can offer you the online interpretation platform “RSI X,” for which we have exclusive usage rights in Japan. This platform is compatible with any online conference system. The smartphone application-based platform has succeeded in reducing “data traffic” while preserving ISO-compliant “voice quality” via a proprietary voice compression technology, delivering smooth remote interpretation even on 3G lines and in weak internet environments. It is ideal for a wide range of purposes, from small meetings to large-scale online seminars between multiple locations, both domestically and internationally.


  • Overwhelmingly the best in reconciling light data volume and voice sound quality

    RSI X has been approved for ISO 20108:2017, which certifies the voice sound quality of communications. The data volume is at a degree of 1/5 that of other companies’ RSI services. It can provide a reliable interpretation voice sound in a great deal of internet environments.

  • Improves versatility through cost reduction

    RSI X reduces the costs associated with transportation and hotel accommodations for interpreter. Furthermore, it removes the need for expensive infrared ray receivers because it can be used with a smartphone, so the user can freely hear the interpretation voice sound wherever they wish.

  • RSI X employs features with high security performance

    In order to protect voice signals that may contain confidential information, it employs the highest standard of SSL as well as AES encryption 256 bit key. The app requires a two-step verification login procedure, offering robust protection for the client’s confidential information.

Introducing RSI X’s specific functions

Background playback

Even when also using other apps, when the screen is turned off, or when a device is in sleep mode, the interpretation voice sound that is run by the RSI X app continues to play back without interruption. It is possible to send and receive emails and chat messages, use other apps to do work, or simultaneously make progress with another task, all while listening to the interpretation voice sound.

Customizable lecture attendance screen

The client’s event title and logo can be added to the lecture attendance screen of the RSI X app, and it is possible to customize the user interface (UI). Users can match conferences and events to their brands, and show their originality.

Web conferencing system screen sharing

On the lecture attendance screen of the RSI X app, it is possible to display the slides and images that are being shared via the Web conferencing system being used for the online event in real time. With this feature, attendees who are not speaking at the conference or event can participate with only one device (such as a computer, smartphone, or tablet).
