Tokaido Shinkansen, one of Japan’s busiest bullet train lines, implemented ReadSpeaker’s AI-powered text-to-speech software to enhance station announcements and improve passenger experience.
Tokaido Shinkansen previously relied on professional voice actors for platform announcements. While these recordings were clear, the station’s noisy environment – filled with moving trains, crowds, and weather-related sounds – often made it hard for passengers to hear. Each recording also required the original voice actor, which was costly and logistically challenging.
JR Central needed a solution that would improve audibility while reducing reliance on voice talent – offering a reliable, cost-effective way to create high-quality, consistent announcements without the limitations of voice actor availability.
ReadSpeaker introduced its advanced TTS solution through the speechMaker Desktop tool, an AI voice authoring platform that enables easy automation of travel announcements for arrivals, departures, and train approaches – eliminating the need for constant voice actor support.
Developed in collaboration with the Yamagishi Laboratory at Japan’s National Institute of Informatics, ReadSpeaker’s software integrates noise-resistant technology to enhance clarity, even in loud environments. This first-of-its-kind feature in transportation ensures clear, intelligible announcements across all platform areas, allowing JR Central to adapt announcements swiftly and cost-effectively.
ReadSpeaker’s AI-powered TTS solution has transformed passenger communication on the Tokaido Shinkansen line.
This implementation places JR Central at the forefront of digital transformation in the transportation industry, setting a new standard for passenger information systems through the power of AI-driven TTS technology. ReadSpeaker’s innovative, noise-resistant TTS solution is a game-changer, enhancing accessibility and improving the overall travel experience for millions of passengers.
JR Central is a major Japanese railway company known for its innovation in high-speed rail. Based in Nagoya, it plays a key role in Japan’s transportation infrastructure and digital transformation.
