A device or software application enables the conversion of spoken words from one language to another. Specifically, it takes audio input in a source language (English, in this instance) and produces corresponding audio output in a target language (Vietnamese). For example, a user speaking into a microphone in English could hear their words reproduced almost instantaneously in Vietnamese.
Such technology bridges communication gaps between individuals who do not share a common language. This facilitates interactions across cultural and linguistic boundaries, enhancing international business, tourism, and personal relationships. These systems have evolved significantly, from early, less accurate prototypes to sophisticated, real-time solutions powered by advancements in natural language processing and machine learning.
