What Is an AI Simultaneous Interpreter?
An AI simultaneous interpreter is a powerful tool or platform designed to provide real-time speech translation during live conversations, meetings, and events. It can also process pre-recorded audio or video files to generate accurate transcripts and translations. By combining capabilities like automatic speech recognition, machine translation, and text-to-speech synthesis, these tools automate complex interpretation tasks. They are built to democratize global communication, allowing users without professional interpreters to overcome language barriers in business, education, and international collaboration.
