Abstract

nvestigations of the Approximate Percentage of Noise Required to Perceive Hindi Phonemes using HNM

Highlights

  • Verbal communication is the ability to convey one’s thought by means of a set of signs, whether graphical, acoustic, gestural, or even musical

  • The value of minima is obtained at a PESQ score of 2.3 approximately, little higher than that found in case of females

  • Pictorial representation of the experimental results is represented in histograms shown in Figure 2, which depicts the consequence of the change in voice and noise percentage on the quality of the synthesized speech of all the six speakers (3 males and 3 females) taken all together

Summary

Introduction

Verbal communication is the ability to convey one’s thought by means of a set of signs, whether graphical, acoustic, gestural, or even musical. The source of vibration called vocal tract, vibrates with the frequency called the pitch frequency (for periodic sounds) normally in the range of 75 Hz to 300 Hz4.Vocal folds in case of males are usually longer (17.5-25 mm) than that in females (12.5-17.55 mm), causing a lower pitch and a deeper voice. This difference in the size of vocal chords causes a difference in vocal pitch[5].
