Gender Recognition of Speech Signal using KNN and SVM

Abstract

Human speech is formulated by the vibration of vocal cord of human being consisting of different sounds for speaking, singing, expressing emotions and ideas, etc .The vocal cord being an important source of sound with human voice as a part of human sound synthesis [3] [5]. Differences in human speech for male and female are due to physiological difference such as vocal fold thickness or vocal tract length. The vocal tracts of male are mostly longer in comparison to vocal tracts of female. With advancing technology and more and more usage of human computer interaction (HCI) based systems, the speech processing plays an important role in enhancing the HCI system [2] [4]. The reason for development of gender recognition system is its used in gender based virtual assistants, telephonic surveys and voice controlled automatic systems.
