Neuroethological investigations of mammalian and avian auditory systems have documented species-specific specializations for processing complex acoustic signals that could, if viewed in abstract terms, have an intriguing and striking relevance for human speech sound categorization and representation. Each species forms biologically relevant categories based on combinatorial analysis of informat...

Traces of the cognitive mechanisms underlying speaking can be found within subtle variations in how we pronounce sounds. While speech errors have traditionally been seen as categorical substitutions of one sound for another, acoustic/articulatory analyses show they partially reflect the intended sound. When "pig" is mispronounced as "big," the resulting /b/ sound differs from correct production...

Articulation errors will seriously reduce speech intelligibility and the ease of spoken communication. Typically, a speech-language pathologist uses his or her clinical experience to identify articulation error patterns, a time-consuming and expensive process. Moreover, the language training is very difficult to articulation disorders for personal training procedure. In this paper, a system wit...

Bone-conducted ultrasound (BCU) can be experienced as sound even by the severely hearingimpaired. We have developed a novel hearing aid using BCU perception (BCU hearing aid: BCUHA) for the profoundly hearing-impaired. Results of evaluation tests suggested its practicability, however, there is room for improvement in terms of articulation. In the BCUHA, ultrasonic sinusoids with a frequency of ...

BACKGROUND The popping produced during high-velocity, low-amplitude (HVLA) thrust manipulation is a common sound; however to our knowledge, no study has previously investigated the location of cavitation sounds during manipulation of the upper cervical spine. The primary purpose was to determine which side of the spine cavitates during C1-2 rotatory HVLA thrust manipulation. Secondary aims were...
