Standardization of acoustic measures for normal voice patterns.
TLDR
Both fo and NHR female measures were significantly higher than their male counterparts, therefore, it is important to standardize the program in use.Abstract:
Summary Studies have established that normative data is necessary for acoustic analysis. The aim of the present study is to standardize fundamental frequency measures (fo), jitter, shimmer and harmonic-noise ratio (HNR) for young adults with normal voice. Method 20 males and 20 females, between 20 and 45 years, without signs and symptoms of vocal problems; CSL-4300 Kay-Elemetrics; vowels /a/ and /e/. Results for females, vowels /a/ and /e/ had average measures of: fo 205.82 Hz and 206.56 Hz; jitter of 0.62% and 0.59%; shimmer of 0.22 dB and 0.19 dB; PHR of 10.9 dB and 11.04 dB, respectively. For males, vowel /a/ and /e/ had average measures of: fo 119.84 Hz and 118.92 Hz; jitter of 0.49% and 0.5%; shimmer of 0.22 dB and 0.21 dB; HNR 9.56 dB and 9.63 dB, respectively. Both fo and NHR female measures were significantly higher than their male counterparts. Conclusion our results differ from the literature; therefore, it is important to standardize the program in use.read more

Objective Voice Analysis of Iranian Speakers with Normal Voices
TL;DR: The majority of voice characteristics of adults was relatively stable and did not change with aging between 20 and 50 years, and the body of normal data for various parameters of acoustic analysis in different age groups and genders of normal Iranian adults was developed.

TL;DR: It is proved in this study that implant recipients postlingually deaf adults (experimental group), without specific vocal rehabilitation, differed from nonrecipients (control group) in loudness and F0 variability sustained vowel /a/ in male participants.

TL;DR: The ability of acoustic measures to discriminate between normal and pathological talkers was investigated and classification accuracy was more accurate for measures extracted from sustained vowels than for those based on continuous speech samples.

TL;DR: HNR was found to be a more sensitive index of vocal function than jitter, and the significant lowering of HNR evident in elderly speakers may be attributable in part to medications taken by the majority of these elderly subjects.

TL;DR: Vocal shimmer during the sustained phonation of /a/, /i/, /u/ was investigated for thirty-one adult male speakers using an automatic analysis program and significant correlations were found among shimmer, jitter and standard deviation.
