The evaluation of cleft palate (CP) speech is a critical clinical treatment. The most typical characteristics of CP speech include hypernasality and consonant misarticulation. Currently, the evaluation of CP speech is carried out by experienced speech therapists. It strongly depends on their clinical experience and subjective judgment. This work aims to propose an automatic evaluation system of resonance...
Speech recorded in real environments by distant microphones is degraded by factor like reverberation. This degradation strongly affects the performance of the speaker identification system. Three compensation approaches are investigated to improve the robustness of speaker identification in such scenarios. The first approach applies spectral subtraction before feature extraction in order to reduce...
Due to the mass-production needs on Powerchip Technology Corporation, the output of equipments is running onto its maximum. Thus, in order to guarantee the delivering time, the transferring control systems around them (AMHS, MCS) are also required to be 100% uptime. For AMHS systems, which are collaborated by multiple similar subsystems, this goal can be easily reached. But for the MCS, which is a...
Radio frequency identify (RFID) is one of technology to facilitate ubiquitous environment. For the ubiquitous environment, it is necessary to model a RFID information framework where based on network. A web service is a Service Oriented Architecture (SOA) that can achieve the purpose. Use the web services by internet; enterprise will exchange information quickly and easy. And enterprise could strategy...
Kernel discriminant analysis (KDA) is a widely used tool for feature extraction. But for high-dimensional multi-class tasks such as face recognition, traditional KDA algorithms have the limitation that the Fisher criterion is nonoptimal with respect to classification rate. Moreover, they suffer from the ldquosmall sample sizerdquo problem. This paper presents a variant of KDA that deals with both...
