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&...

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...
