Problems solved by technology

However, in the conventional speech translation system, there is no technology for automatically converting the prosodic feature of the speech, and the difference information between the prosodic feature pattern of the input and output speech and the standard prosodic feature pattern is not used, so sufficient accuracy cannot be obtained.

Abstract

Provided is a speech translation system for receiving an input of the original speech in a first language, translating an input content into a second language, and outputting a result of the translating as a speech, including: an input processing part for receiving the input of the original speech, and generating, from the original speech, an original language text and the prosodic information of the original speech; a translation part for generating a translated sentence by translating the first language into the second language; prosodic feature transform information including associated prosodic information between the first language and the second language; a prosodic feature transform part for transforming the prosodic information of the original speech into prosodic information of the speech to be output; and a speech synthesis part for outputting the translated sentence as a speech synthesized based on the prosodic information of the speech to be output.

Description

technical field [0001] The present invention relates to a technique for converting voice data input in a source language into a target language for voice output. Background technique [0002] In recent years, as international communication has prospered, the need for multilingual communication has increased, and multilingual interpretation is required in order to realize multilingual communication. As a means of realizing multilingual communication, along with the improvement of computer processing power and the use of large-capacity databases, speech recognition technology, natural language processing technology, and especially the speed and accuracy of text mechanical translation technology have been improved. Furthermore, high-quality voice synthesis technology has been advanced, and a multilingual voice translation device using these technologies can be realized (for example, refer to Patent Document 1). [0003] In an audio translation device, a technique is disclosed ...
