Problems solved by technology

However, phrase-based sentences are extremely difficult for users to remember.
Quite often users forget the sentences and generally become frustrated with the approach.
The free-form approach is used sometimes to resolve this problem but the quality of the free-form approach is not substantially guaranteed.
Unfortunately, to the user's detriment, a user desiring a speech translation apparatus is limited to either a (1) phrase-based or (2) a free-form speech-to-speech tran

Embodiment Construction

[0017]Modern speech-to-speech recognition systems aim toward facilitating communications between people speaking different languages. To achieve this goal, a typical speech translation system (1) collects the speech signal from one speaker, (2) recognizes the speech in the source language, (3) translates the recognized messages into the target language, (4) synthesizes the speech sound of the translated sentence, and (5) plays it by way of a speaker. Steps (2), (3) and (4) are commonly realized by the techniques of automatic speech recognition (ASR), machine translation (MT) and text-to-speech synthesis (TTS), respectively.

[0018]Current speech-to-speech translation systems realize the above translation function by way of two main speech translation approaches: (i) phrase-based (also commonly known as sentence-based) and (ii) free-form. The phrase-based translation approach (i) carries out speech-to-speech in the following manner:[0019]1) Record the whole speech sentence from one spe...

Abstract

An apparatus and method that integrates both phrase-based and free-form speech-to-speech translation approaches using probability models. The starting step of the method is to receive vocal communication in a source language. Then store the received vocal communication. Then decipher the content of the vocal communication. Then locate in a multilingual dictionary module the corresponding translation of the deciphered vocal communication provided a preset sentence exists in a speech recognition module for the vocal communication. Then translate the vocal communication into the target language provided there is no corresponding translation located in the multilingual dictionary module. Then synthesize the translated target language when there is no corresponding translation for the vocal communication in the multilingual dictionary module. Then store the sound of the translated target language. Then play the sound of the translated target language.
