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...

As the voice source is the primary sound itself, which after filtering by the vocal tract resonator is radiated through the l...
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...
