Abstract: Provided a method performed by an automatic interpretation server based on a zero user interface (UI), which communicates with a plurality of terminal devices having a microphone function, a speaker function, a communication function, and a wearable function. The method includes connecting terminal devices disposed within a designated automatic interpretation zone, receiving a voice signal of a first user from a first terminal device among the terminal devices within the automatic interpretation zone, matching a plurality of users placed within a speech-receivable distance of the first terminal device, and performing automatic interpretation on the voice signal and transmitting results of the automatic interpretation to a second terminal device of at least one second user corresponding to a result of the matching.

Abstract: Provided is a method of performing automatic interpretation based on speaker separation by a user terminal, the method including: receiving a first speech signal including at least one of a user speech of a user and a user surrounding speech around the user from an automatic interpretation service providing terminal, separating the first speech signal into speaker-specific speech signals, performing interpretation on the speaker-specific speech signals in a language selected by the user on the basis of an interpretation mode, and providing a second speech signal generated as a result of the interpretation to at least one of a counterpart terminal and the automatic interpretation service providing terminal according to the interpretation mode.

Abstract: Disclosed are a Zero User Interface (UI)-based automatic speech translation system and method. The system and method can solve problems such as the procedural inconvenience of inputting speech signals and the malfunction of speech recognition due to crosstalk when users who speak difference languages have a face-to-face conversation. The system includes an automatic speech translation server configured to select a speech signal of a speaker from among multiple speech signals received from user terminals connected to an automatic speech translation service and configured to transmit a result of translating the speech signal of the speaker into a target language, a speaker terminal configured to receive the speech signal of the speaker and transmit the speech signal of the speaker to the automatic speech translation server, and a counterpart terminal configured to output the result of the translation in a form of text or voice in the target language.
