This paper presents a design of pitch controller using Genetic Algorithm (GA) for variable speed wind turbine Doubly Fed Induction Generator (DFIG) . The proposed genetic pitch controller is used to get the proper pitch angle for limiting the mechanical power when the wind speed is greater than the rated wind speed. DFIG is a wound-rotor induction generator where the stator terminals of DFIG ar...

Musical ensemble performance requires precise action coordination. To maintain synchrony in the presence of expressive tempo variations, musicians presumably anticipate the sounds that will be produced by their co-performers and coordinate their own anticipated actions with these predictions. Anticipatory auditory images in pitch and time may facilitate such predictions. Two experiments were co...

In the presented work, we explore some of the challenges in recognizing children’s speech on automatic speech recognition (ASR) systems developed using adults’ speech. In such mismatched ASR tasks, a severely degraded recognition performance is observed due to the gross mismatch in the acoustic attributes between those two groups of speakers. Among the various sources of mismatch, we focus on t...

Melodic intonation therapy (MIT) is a structured protocol for language rehabilitation in people with Broca's aphasia. The main particularity of MIT is the use of intoned speech, a technique in which the clinician stylizes the prosody of short sentences using simple pitch and rhythm patterns. In the original MIT protocol, patients must repeat diverse sentences in order to espouse this way of spe...

Whether music and language evolved independently of each other or whether both evolved from a common precursor remains a hotly debated topic. We here emphasize the role of vowels in the language-music relationship, arguing for a shared heritage of music and speech. Vowels play a decisive role in generating the sound or sonority of syllables, the main vehicles for transporting prosodic informati...

The Output power of wind turbine is determined by wind speed. The Output power can be adjusted by controlling the generator speed and pitch angle of wind turbine. When the wind speed below the wind turbine rated, the output power of generator can be maximized by controlling the generator speed at point of maximum power coefficient. When the wind speed above the wind turbine rated, output power ...

. The present study deals with a voice quality that is referred to as “intelligible” or “articulate” voice. The purpose of the present study is to find a relation between the voice quality and acoustic features. The speech material is a read version of a simple short Japanese sentence “a o i so ra” in order to eliminate these linguistic variations. A set of speech samples uttered by fifteen adu...

A new method and application is proposed to characterize intensity and pitch of human heart sounds and murmurs. Using recorded heart sounds from the library of one of the authors, a visual map of heart sound energy was established. Both normal and abnormal heart sound recordings were studied. Representation is based on Wigner-Ville joint time-frequency transformations. The proposed methodology ...

PURPOSE OF REVIEW The superior laryngeal nerve (SLN) provides motor innervation to the cricothyroid muscle. However, the functions of this muscle and the anatomic variations of the nerve that supplies it are not fully understood. SLN paresis and paralysis (SLNp) is difficult to diagnose because of a lack of consistent laryngeal findings, and its effects on the voice likely go beyond simple pitc...

This paper examines the F0 variations during tone sandhi due to various prosodic factors such as phonation type, length, stress and pitch height. It will be shown that the F0 height and shape of the second syllable (S2) in disyllabic words are determined by the interaction of four conditions: the intervocalic consonant (C2) voicing, the S2 Truncation, the F0 height of S1, and stress assignment.
