Abstract: A system and a method of speech recognition which enable a spoken language to be automatically identified while recognizing speech of a person who vocalize to effectively process multilingual speech recognition without a separate process for user registration or recognized language setting such as use of a button for allowing a user to manually select a language to be vocalized and support speech recognition of each language to be automatically performed even though persons who speak different languages vocalize by using one terminal to increase convenience of the user.

Abstract: Disclosed are an apparatus for recognizing voice using multiple acoustic models according to the present invention and a method thereof. An apparatus for recognizing voice using multiple acoustic models includes a voice data database (DB) configured to store voice data collected in various noise environments; a model generating means configured to perform classification for each speaker and environment based on the collected voice data, and to generate an acoustic model of a binary tree structure as the classification result; and a voice recognizing means configured to extract feature data of voice data when the voice data is received from a user, to select multiple models from the generated acoustic model based on the extracted feature data, to parallel recognize the voice data based on the selected multiple models, and to output a word string corresponding to the voice data as the recognition result.

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.
