Paraphrase - Essay Example One inclusive cycle of the waveform, or the time in which it takes to complete, is referred to as a period. Another component of a sinusoid is the amplitude, or the total quantity of pressure variation surrounding the mean of the wavelength. The final specification of a sinusoid is the part of the cycle where the wave progresses relative to a particular fixed point in time, referred to as the phase. Phase is only a crucial aspect to consider for the measurement of continuous sinusoids, because one is forced to reflect upon the relationship between two or more different waves, rather than just a single wave. However, because the vowel is considered to be a complex waveform, it can be evaluated by converting the complex waveforms into a series of sinusoids distinguished by specific frequencies, amplitudes and phases. In doing so, it is determined that a vowel has two difference frequencies, one high and one low. The sinusoids of low frequency lean towards a higher amplitude, while the sinusoids of high frequency are nearly equally balanced in amplitude from the mean. The combination of two sinusoids of two different frequencies results in a complex wave. This is accomplished by adding low and high frequencies, in which the frequency is maintained in the resulting wave. Also, a complex wave can be formed by adding two amplitudes at a suitable point in time. The perceived shape of the complex wave is reliant upon the relative frequency, amplitude and phase of each aspect of the sine wave. Vowel acoustics are examined by the relative results of the formants. According to Benade in the 1976 study, formants are â€Å"the peaks that are observed in the spectrum envelope†. This can be observed through dark bands which appear on a spectrogram, signifying acoustic resonances emitted from the vocal tract. The vocal tract operates as a resonant cavity and the placement of certain facial features, including the tongue, jaw and lips, results in different
