Advanced Smart Mobility Deploys Cerence Emergency Vehicle Detection in Autonomous Buses Across Japan
Rhea-AI Summary
Cerence (NASDAQ: CRNC) announced that Advanced Smart Mobility (AS Mobi) is deploying Cerence Emergency Vehicle Detection (EVD) in its autonomous bus platform field trials across multiple regions in Japan. The technology uses Audio AI and exterior microphones to detect approaching ambulances, police vehicles, and fire engines so autonomous buses can respond appropriately in complex, real‑world environments.
According to Cerence, this is its first autonomous bus program in Japan and the first deployment of EVD using exterior microphones. EVD supports more than 1,500 sirens across 47 countries and is designed to distinguish emergency sirens from traffic and environmental noise, complementing cameras, radar, and LiDAR. AS Mobi targets future commercial deployment of its autonomous transportation services in 2027 as it seeks to address Japan’s aging population and driver shortages.

BURLINGTON, Mass. and TSUKUBA, Japan, Aug. 25, 2026 (GLOBE NEWSWIRE) -- Cerence Inc. (NASDAQ: CRNC) (“Cerence AI”), a global leader in conversational AI-powered user experiences, today announced that Advanced Smart Mobility Co., Ltd. (AS Mobi) is deploying Cerence Emergency Vehicle Detection (EVD) to support its autonomous bus platform field trials in Japan. The collaboration supports safer transportation journeys, helping autonomous vehicles recognize approaching emergency vehicles and respond appropriately in complex, real-world environments.
Emergency vehicle awareness is an important challenge for autonomous transportation systems operating on public roads. Emergency vehicles are often audible before they are visible, particularly in dense urban environments, around intersections, or when visibility is limited. An ambulance approaching from behind traffic or a fire engine navigating through a congested city corridor may be heard well before it enters a vehicle’s field of view.
Guided by its mission to expand access to safe, sustainable transportation, AS Mobi’s autonomous mobility solutions help address critical transportation challenges in Japan, including an aging population and driver shortages.
Taking place across multiple regions in Japan, the field trials represent Cerence AI’s first autonomous bus program in the country and reflect AS Mobi’s broader vision to scale autonomous transportation services, with future commercial deployment targeted for 2027. The collaboration also marks the first deployment of Cerence EVD using exterior microphones.
Cerence EVD uses Audio AI technology to detect approaching ambulances, police vehicles, and fire engines, helping autonomous vehicles take appropriate action. The solution supports more than 1,500 sirens across 47 countries and is designed to distinguish emergency sirens from traffic noise and other environmental sounds. EVD complements cameras, radar, LiDAR, and other sensing technologies used in autonomous driving systems, providing an additional layer of environmental awareness.
“Our focus is addressing transportation challenges through safe and reliable autonomous mobility solutions,” said Masaya Segawa, President at AS Mobi. “Emergency vehicle awareness is an important capability for autonomous bus operations, and our collaboration with Cerence AI supports our efforts to advance transportation services that are safer, more accessible, and better equipped for the dynamic challenges of real-world environments.”
“As autonomous mobility moves from controlled testing environments to real-world transportation services, vehicles need a broader understanding of their surroundings,” said Christian Mentz, Chief Revenue Officer at Cerence AI. “When emergency responders are navigating through traffic, every moment matters. EVD helps autonomous systems identify approaching ambulances, fire engines, and police vehicles early and take appropriate action, supporting better transportation systems and safer communities.”
