Sentence examples for fundamental frequency variance from inspiring English sources

However, in practical applications, the accuracy of harmonic estimation would be reduced under some situations, especially in cases of fundamental frequency variance and background noise presence.

In a next step, we computed relative values for fundamental frequency variance and articulatory quality.

Based on these values, a correlation between fundamental frequency variance and articulatory quality did not yield significant results [ r(16) = −0.19, NS].

'Praat' was used to quantify the fundamental frequency variances in the conditions melodic intoning and rhythmic speech separately for each lyric type.

Since the discussed procedure uses the same information in finding the fundamental frequency and the noise variance, it is superior to the least-squares approach in terms of computational complexity.

In addition, the proposed fundamental frequency estimation algorithm has good tracking capability and lower variance of frequency estimation error than that of the conventional cascade ANF method.

By combining the variance estimate in (101) with (85), we obtain the following fundamental frequency estimator for the case of unknown model orders (for L k > 0): (102).

The variance estimate in (101) involves the same expression as in the fundamental frequency estimation criterion in (42), which means that the same expression can be used for estimating the model order and the fundamental frequency, i.e., the approach allows for joint estimation of the model order and the fundamental frequency.

DFA: discriminant function analysis; F0: fundamental frequency; lmer: linear mixed effect models; ncce: number of correctly cross-classified elements; pDFA: permutated discriminant function analysis; VIF: variance inflation factors.

Variation in subsyringeal pressure can partially explain variations in fundamental frequency, as the positive regression between fundamental frequency and pressure before and after the neurotomy suggests (Figure 4).

Harmonics are a series of overtones resulting when the frequencies are exact multiples of the fundamental frequency.
