Grab Singapore has launched Grab AI Call-A-Ride (Beta), a service allowing users to book rides by speaking to an artificial intelligence voice assistant via phone call at +65 3138 0000. Designed to assist seniors and those who find mobile app navigation difficult, the system uses OpenAI’s Realtime Voice model to interpret user intent and process bookings through natural conversation.
How the AI Voice Assistant Works
Unlike traditional automated phone systems that rely on rigid menu prompts, the Grab AI Call-A-Ride (Beta) uses conversational AI to handle requests. According to Grab, the technology can maintain context, adapt to user input mid-sentence, and interpret intent in real time. This capability is powered by OpenAI’s Realtime Voice model, which the company claims allows for more fluid interaction than previous generations of automated voice services.
The service is currently optimized for English and Mandarin. To ensure the system understands local nuances, Grab integrated over 100,000 voice sample donations collected in Singapore, specifically to help the AI parse Singlish and regional accents. Grab also implemented a voiceprint solution designed to isolate a user’s voice from background noise, a common technical hurdle for voice-based AI.
Did you know?
The new AI call service builds upon technical foundations from Grab’s Voice Assistant for the Visually Impaired, which was first introduced in 2025 to help users navigate the Grab app interface.
Bridging the Digital Divide for Seniors
The pilot program aims to address a “long-standing paradox” in tech: the trade-off between the scalability of apps and the accessibility of traditional human-agent call centers, according to Philipp Kandal, Grab’s chief product officer. By moving away from app-only requirements, the company seeks to provide reliable mobility to users who struggle with digital interfaces.
Prior to the public launch on August 5, 2026, the system underwent a trial involving approximately 1,000 calls. Grab partnered with organizations such as the Infocomm Media Development Authority (IMDA)’s SG Digital Office and Temasek to test the service with various demographic groups, including seniors at digital literacy workshops. Feedback from these trials was used to refine the system’s speech recognition and conversational pacing.
Technical Collaboration and Future Expansion
The collaboration between Grab and OpenAI marks a shift toward designing AI specifically for regional needs. Albert Yip, OpenAI’s head of technical success for Asia-Pacific, noted that the service demonstrates how foundational voice models can be applied to solve real-world accessibility challenges. While currently available only in English and Mandarin, Grab has confirmed plans to expand the service to support more regional languages in the future.
