Speech-to-Speech Translation: A Review

A Speech - to - Speech Translation based Interfacefor

This paper presents a speech-to-speech translation system for tourism application developed in the context of the C-STAR consortium. Potential users can communicate by speech and by using their own language with a travel agent in order to organize their travel. The system uses an interchange format representation of the semantic contents of utterances, which is exible and simpliies the system p...

Hierarchical classification for speech-to-speech translation

Concept classifiers have been used in speech to speech translation systems. Their effectiveness, however, depends on the size of the domain that they cover. The main bottleneck in expanding the classifier domain is the degradation in accuracy as the number of classes increase. Here we introduce a hierarchical classification process that aims to scale up the domain without compromising the accur...

Incremental Adaptation of Speech-to-Speech Translation

In building practical two-way speech-to-speech translation systems the end user will always wish to use the system in an environment different from the original training data. As with all speech systems, it is important to allow the system to adapt to the actual usage situations. This paper investigates how a speech-to-speech translation system can adapt day-to-day from collected data on day on...

The NESPOLE! Speech-to-Speech Translation System

Finite-state speech-to-speech translation

A fully integrated approach to Speech-Input Language Translation in limited-domain applications is presented. The mapping from the input to the output language is modeled in terms of a nite state translation model which is learned from examples of input-output sentences of the task considered. This model is tightly integrated with standard acoustic-phonetic models of the input language and the ...
