What Is an AI Speech Translation Tool?
An AI speech translation tool is a powerful platform designed to interpret and translate spoken language in real-time or from audio files. It combines multiple AI capabilities—such as automatic speech recognition (ASR), machine translation (MT), and text-to-speech (TTS)—into a seamless workflow. These tools are built to democratize global communication by breaking down language barriers, allowing users to understand and be understood instantly in meetings, calls, and webinars, regardless of the languages being spoken.
