Voice is that the sound produced during a person's larynx and uttered through the mouth, as speech or song. Voice is generated by airflow from the lungs because the vocal folds are brought approximately. When air is pushed past the vocal folds with sufficient pressure vocal folds vibrate and make sound. Menopause is defined because the purpose at the time when the cycle permanently ceases because of natural depletion of ovarian oocytes from aging. PRAAT could also be a really flexible tool to
... dertake to do speech analysis. The PRAAT software is made by Boersma and Weeniak from university of Amsterdam . The aim of the study was to live and describe the changes and acoustic voice analysis in typical Malayalam speaking menopause individual within the age range between 50 to 70 years using PRAAT software. The subjects were seated and therefore the recordings were made employing a microphone attached to a Del laptop in a quiet noise free illuminated environment. The microphone was placed at a distance of 8-10cm from the subject mouth. Subjects were asked to take a deep breath and phonate /a/, /i/, /u/ as long as possible at a comfortable pitch level. This was demonstrated by examiner for all subjects. The result shows that the highest mean pitch for vowel /u/. The highest mean minimum pitch for menopausal female observed for vowel /u/. The highest mean maximum pitch for menopausal female was observed for vowel /u/. The highest mean jitter and shimmer value for menopausal female was observed for vowel /u/. The highest mean NHR value of menopausal female was observed for vowel /u/. But the highest mean HNR value of menopausal female was observed for value /i/.In conclusion, the acoustic parameter tested that is [mean pitch, minimum pitch, maximum pitch, jitter, shimmer, NHR] the highest mean value of menopause female was observed for vowel /u/ but in HNR the highest mean value was observed for vowel /i/. And the lowest mean value for all the parameter [mean pitch, minimum pitch, maximum pitch, jitter, shimmer, HNR] except NHR was observed for vowel /a/ in menopausal female. For NHR the lowest mean value was observed for vowel /i/.
