Yamaha Launches 'Smartphone Receiver,' a Local Audio and Subtitle System That Requires No Internet

Yamaha Corporation announced that it will launch 'Smartphone Receiver,' a local audio and subtitle system utilizing its proprietary 'SoundUD' technology, on June 11, 2026. The system will be adopted as the receiver solution for the keynote speech at 'Interop Tokyo 2026,' starting June 10 at Makuhari Messe, and will also be showcased at the Yamaha booth.

The system enables the delivery of audio and subtitles to users' smartphones within a local network, without the need for an internet connection. It also implements local-based speech recognition and automated translation features, supporting accessibility and universal design in international conferences and various events.

Background:
Infrared receivers and subtitle display units used in international conferences have long presented operational burdens regarding distribution, collection, and maintenance. Furthermore, smartphone-based receiver services are often susceptible to venue and communication conditions, hindering their adoption in high-security meetings.

Yamaha addressed these issues by developing a receiver system that delivers audio/subtitles within a local network, independent of internet environments. It also includes local speech recognition and translation to reduce the burden of multilingual support.

Key Features:
- No Internet Required: Operates within a local network, ensuring high security suitable for confidential information.
- Reduced Burden for Organizers: Eliminates the need for dedicated hardware management.
- Leverages Attendees' Smartphones: No dedicated app required; accessible via simple QR code scanning.
- Universal Design Support: Flexible multilingual delivery utilizing speech recognition and automated translation.
