Analysis of Fundamental Frequency, Jitter and Shimmer in Stuttered and Non-Stuttered Speech of Marathi Language

Stuttering is one of the complex speech disorder which lead speech unintelligible to other and ASR system. In this paper Fundamental frequency (f0), vocal jitter and shimmer were measures the numerical words of 17 Stuttering (PWS) (i.e. 13 Male and 4 female) and 25 Non-Stutterers (NS) (i.e. 15 male 10 female) belongs to the Marathi Language. Jitter and shimmer are measurements of the cycle - to - cycle variations of F0 frequency and amplitude, respectively, which were largely used to describe pathological voice quality. The experiment performed with Pasrelmouth Praat Scripts in Python. This is the first attempt for the Marathi Language. Shimmer were shows the negligible difference between PWS and NS speech samples.
