Sensitive Test of Speech Communication Quality

Quality-Sensitive Test Set Selection for a Speech Translation System

We propose a test set selection method to sensitively evaluate the performance of a speech translation system. The proposed method chooses the most sensitive test sentences by removing insensitive sentences iteratively. Experiments are conducted on the ATR-MATRIX speech translation system, developed at ATR Interpreting Telecommunications Research Laboratories. The results show the effectiveness...

Quality Assessment of Wideband Speech Communication Services

This article describes a method for estimating the subjective quality of wideband (7-kHz) speech solely from physical characteristics of terminals and networks. It enables efficient quality design and management of wideband speech communication services. The validity of this model was shown through experiments.

Speech Quality Tests of In-Car Communication Systems

Improving Quality of Service in Baseband Speech Communication

Speech is the most important communication modality for human interaction. Automatic speech recognition and speech synthesis have extended further the relevance of speech to man-machine interaction. Environment noise and various distortions, such as reverberation and speech processing artifacts, reduce the mutual information between the message modulated in the clean speech and the message deco...
