Thus, this paper aims to analyze the relationship between such acoustic measures and auditory-perceptual analysis and then determine which acoustic measure best represents voice quality. Until now, little has been known about how physiological events impact auditory-perceptual characteristics in the objective measures of CPPs and LTAS (alpha ratio L1-L0). The present study provides the reference values for CPP and sCPP across various stimuli.Д¬epstral peak prominence-smoothed (CPPs) and long-term average spectrum (LTAS) are robust measures that represent the glottal source and source-filter interactions, respectively. The data was subjected to statistical analysis using SPSS (version 21).

The cepstral analysis was done using speech tool software (version 1.65). Hundred adults in the age range of 20вЂ“40 years with equal number of males and females were considered and the task includes to phonate vowels /a/, /i/ and /u/ for five seconds each and to read вЂњ300 word Kannada reading passageвЂќ (Savithri & Jayaram, 2005) and the Bengaluru passage. Thus, the present study aimed to investigate the reference values for CPP and sCPP in young adults with normal voice in the age range of 20вЂ“40 years. Cepstral analysis has been reported to be a reliable and valid measure for voice evaluation even for signals with high level of aperiodicity, which the time based measures fails to evaluate. CPP is determined by measuring the amplitude difference from the highest peak of the cepstrum to the corresponding regression line, drawn directly below the cepstral peaks and when a smoothening factor is applied, sCPP is obtained. The two commonly studied cepstral measures are Cepstral Peak Prominence (CPP) and smoothened Cepstral peak prominence (sCPP).

The fundamental frequency and harmonic organization of voice can be quantified using cepstral measure.
