background : a head and neck (h&n;) cancer severely affect the voice and compromises the patient’s vocal independence. the present study proposed to investigate the difference in the three vital components of voice the pitch, jitter and shimmer in h&n; cancer patients and compared it with age matched healthy volunteers. methods : the voice parameters were ascertained in the freshly diagnosed h&...

16 isolates of fusarium culmorum obtained from washington, north dakota and minnesota were tested for pathogenicity on five cultivars and lines: chevron, ci 9549, excel, karl, larker, morex, robust, m48, m66 and m69 were evaluated for reaction to the mixture of all isolates of the pathogen under field condition. the results of glasshouse test indicated that the isolates 10, 25 and 27 were the m...

Multi-pitch estimation of co-channel speech is especially challenging when the underlying pitch tracks are close in pitch value (e.g., when pitch tracks cross). Building on our previous work in [1], we demonstrate the utility of a two-dimensional (2-D) analysis method of speech for this problem by exploiting its joint representation of pitch and pitch-derivative information from distinct speake...

Neural representation of pitch-relevant information at both the brainstem and cortical levels of processing is influenced by language or music experience. However, the functional roles of brainstem and cortical neural mechanisms in the hierarchical network for language processing, and how they drive and maintain experience-dependent reorganization are not known. In an effort to evaluate the pos...
