    of movement required for speech production. (18) Dysarthria is a common symptom of many neurological disorders, and the features of the speech dysfunction are distinctive. (17) Classic dysarthric presentations are characterised by a disturbance in the subsystems of speech, namely respiration, phonation, articulation, and resonance, resulting in reduced speech intelligibility and quality. (18) Dysarthria is a cardinal and salient clinical symptom in FRDA (2, 19, 20) with a prevalence of 91%. (20) The severity of the dysarthria associated with this disorder ranges from mild to severe. (21) The heterogeneous and pervasive underlying…

    Figure 2 demonstrates the variation of positively compensated admittance (Ytm), susceptance (Btm), and conductance (Gtm) as a function of probe tone frequency. While acoustic resistance is independent of frequency, acoustic conductance does vary with frequency. The variation of Ga with frequency can be understood as a variation of Ra and Xa with frequency. Stiffness and mass susceptance are frequency dependent. Mass susceptance is directly proportional to frequency and stiffness susceptance is…

    of the bottle and depends on the length of the neck, the diameter of the opening and the volume of the bottle. No matter how much energy is introduced, such as blowing soft or hard across the opening, the bottle will produce the frequency which is unique to it. Theory To create a useful equation to estimate the resonance frequency of a bottle, three forces must be combined. Newton’s second law can be used to find the elastic, dissipation, and driving forces that act on the bottle to obtain the…

    chimera is composed from two different sounds; the envelope of one sound and the fine structure of another. Scientists have discovered that human speech is dominated by the envelope information of a speech sound, where as musical melodies is dominated by the fine structure of the sound by using auditory chimeras. Tonal languages utilize speech intonations to express different word meaning and usually include various distinctive pitch contours. For our research, we used auditory chimeras to…

    The reason why engineer’s might bring in effects to a vocal track is mostly to create an aural space or even to add excitement. Many engineers describe effects as something that can make the vocal track sound deeper, wider or even bigger. “Everything has to be bigger always. Effects are makeup. It’s cosmetic surgery. I can take a very great song by a very great band and mix it with no effects on it at all, and it’ll sound good, and I can take the same song and mix it with effects and it’ll sound…

    A large mound of fat called acoustic lipids[5] and this mound often called a melon[9]. The clicks by the toothed whales are generated within interconnected channels behind the melon .[1] The dolphin is able to change the shape of the melon and become an acoustic lens which condenses the waves in to a beam.[5] The echoes are received at a point in the lower jaw of the animal sometimes called the “acoustic window”. This section is also fat filled and helps the wave travel to the dolphins ear,…

    Childhood apraxia of speech (CAS) CAS is a pediatric neurological speech sound disorder. This disorder impairs the precision and consistency of the movements that underlie speech. However neuromuscular deficits are absent. It may be the result of a known neurological impairment, and include complex neurobehavioral disorders with known or unknown origins. It may also occur as an idiopathic neurogenic speech sound disorder. The main impairment in planning and/or programming spatiotemporal…
