What Is an AI Simultaneous Interpretation Tool?
An AI simultaneous interpretation tool is a sophisticated software or device that provides real-time voice translation during live conversations, meetings, or events. It uses advanced AI, including automatic speech recognition (ASR) and neural machine translation (NMT), to listen to a speaker in one language and instantly deliver an audio or text translation in another. These tools range from fully automated systems for online meetings and developer APIs to portable devices for travel and enterprise platforms that blend AI with human interpreters, democratizing communication by removing language barriers instantly.
