Real-time voice translation that keeps pace with a live conversation, and translates phone calls the other person answers on their normal phone. 35 languages. LiveLingo is a real-time voice translator for spoken conversation. Translation arrives at about 1.5 seconds, while the other person is still speaking, so people talk naturally instead of taking turns passing a phone back and forth. It also translates live phone calls over PSTN. You dial a normal number and the person on the other end simply answers their own phone, with no app or setup on their side. That covers hotels, clinics, landlords, taxi drivers and overseas suppliers, where camera and text translators stop being useful. LiveLingo supports 35 languages and runs on iOS, Android and the web, using the phone you already have rather than extra hardware. We published the accuracy data instead of only claiming it: a 16-corridor benchmark in which every system received identical audio and three independent LLM judges scored the output. LiveLingo ranked first on both latency and accuracy, ahead of Gemini Live, GPT Live API and Azure. The dataset is open under CC-BY.
