An integrated voice analyzer for evaluating pathological voice

Voice Stress Analyzer Instrumentation Evaluation

Text-dependent pathological voice detection

While global characteristics of the speaker’s source and spectral features have been successfully employed in pathological voice detection, the underlying text has largely been ignored. In this work, we focus on experiments that exploit the text stimulus that is read by the subject. Features derived from text include the mean cepstral distortion of the subject from an average intelligible speak...

Source Model Adequacy for Pathological Voice Synthesis

Pathological voices are particularly difficult to inverse filter and fit with source models, in part, because of source-tract interactions inherent in these voice types. In order to obtain good synthetic copies of these voices, we need to know the practical importance of accurately inverse filtering and modeling individual voice sources. To this end, thirty different voices were synthesized, ea...

Pathological Voice Recognition for Vocal Fold Disease

Pathology is the study and diagnosis of disease. Due to the nature of job, unhealthy habits and voice abuse, the people are subjected to the risk of voice problems. The diagnosis of vocal and voice disorders should be in the early stage otherwise it causes changes in the normal signal. It is well known that most of vocal fold pathologies cause changes in the acoustic voice signal. Therefore, th...

On handoff performance for an integrated voice/data cellular system

One of the key challenges in the design of bandwidth allocation policies for a multi-services mobile cellular network is to guarantee the potentially different Quality of Service (QoS) requirement from diverse applications, while at the same to ensure that the scarce bandwidth be utilized efficiently. Complete Sharing (CS) and Dynamic Partition (DP) schemes have been shown as viable techniques ...
