Assistive communication tool producing zero-latency captioning streams for telephone and digital audio.
Rylo is an assistive communication tool producing zero-latency captioning streams for telephone and digital audio streams, designed to improve communication access for deaf and hard-of-hearing users. The company raised USD 85m, highlighting growing investor interest in accessibility technologies as a distinct investment category within language AI. Rylo's focus on telephony captioning addresses one of the most persistent accessibility gaps for deaf users — real-time captioning of voice telephone calls, which remain a primary communication channel in healthcare, government, financial services, and emergency response contexts.
