An important parameter in quality assessment of speech enhancement systems is speech distortion, measured in terms of quality of the speech component. In fact, in the context of noise reduction, the user tends to prefer a certain degree of residual noise over distorted speech with suppressed background noise. The challenge of instrumental speech component quality evaluation lies, among others, ...

In mobile devices, perceived speech signal degrades significantly in the presence of background noise as it reaches directly at the listener's ears. There is a need to improve the intelligibility and quality of the received speech signal in noisy environments by incorporating speech enhancement algorithms. This paper focuses on speech enhancement method including auditory masking propertie...

The present work was carried out to investigate the relation between a speaker’s age and the quality of the encoded speech for several, well known speech coding techniques and a commercially available vocoder CMX618. For this purpose, a corpus of speech records obtained from speakers of various age and gender groups was created. The PESQ (Perceptual Evaluation of Speech quality) method was used...

Kei Kikuiri, Nobuhiko Naka and Shinya Abe The high-quality speech coding is a super-wideband speech coding technique for providing high-quality VoIP services in a high-speed wireless communication environment, and was developed in collaboration with DoCoMo Communications Laboratories USA, Inc. This technology encodes and transmits nearly all of the frequency components of the human voice to all...

Portability is an important issue to the viability of a domainspecific translation approach. This paper describes an English to Chinese translation system for flight-domain queries, utilizing an interlingua translation framework that has been successfully applied in the weather domain. Portability of various components is tested, and new technologies to handle parse ambiguities and illformed in...

Unwanted noises have a negative influence over communication because it disturbs the conversation and make the communication impossible. Speech enhancement algorithms are used for improving the quality and intelligibility or to reduce listener fatigues. Assessment of speech quality can be done by using either subjective listening test or objective quality measure. Evaluation of several objectiv...
