Abstract :
The fundamental frequency (Fo) of speech conveys prosodic information regarding normal communication patterns. Hence, it is essential that the Fo be measured accurately in assessing and in rehabilitating deaf speech. This paper describes the differences obtained using two different methods, electroglottograph (EGG), and fast fourier transform (FFT) for measuring the Fo in deaf and normal hearing speakers.
