Effect on LTAS of vocal loudness variation.
Long-term-average spectrum (LTAS) is an efficient method for voice analysis, revealing both voice source and formant characteristics. However, the LTAS contour is non-uniformly affected by vocal loudness. This variation was analyzed in 15 male and 16 female untrained voices reading a text 7 times at different degrees of vocal loudness, mean change in overall equivalent sound level (Leq) amounti...
متن کاملEffect of vocal loudness variation on the voice source
The physiological correlate of perceived vocal loudness is the overpressure of air under the glottis, or the subglottal pressure Psub. Variation of vocal loudness, i.e., of Psub has strong effects on the waveform of the transglottal airflow, also called the voice source. As the voice source is the primary sound itself, which after filtering by the vocal tract resonator is radiated through the l...
متن کاملLong-term average spectrum loudness variation in speakers with asthma, paradoxical vocal fold motion and without breathing problems
Introduction: Vocal loudness variation can influence the reability of acoustics analysis. Therefore an intensity acoustic measure such as the Long Term Average Spectrum (LTAS) should be submitted to standard calibration and analysis procedures for realistic results. Purpose: The purpose of this study is to compare the LTAS intensity measures with and without implementation of intensity averagin...
متن کاملModeling Temporal Effects of Spectral Loudness Summation
Recent studies have shown that spectral loudness summation depends on duration. Modifications of a current loudness model were investigated with respect to their ability to predict this effect. The original version of the model could not simulate the duration dependence of spectral loudness summation. To reconcile the model with the loudness data, three different mechanisms accentuating tempora...
متن کاملThe Effect of Vocal Loudness on Nasalance of Vowels in Persian Adults
Objectives: Nasality is one of the important parameters in pathology of voice resonance. Voice of normal adults has nasality to some extent. It appears that nasality, like other parameters of voice, can be affected by loudness which can be measured in experimental evaluations. This study was conducted to determine the effect of vocal loudness on nasalance of vowels in normal adults and to ident...
