Speech is the basic mode of communication for humans, and hence it is of utmost importance that it is heard intelligibly. The intelligibility of speech relies upon the properties such as acoustical data in which the voice is transmitted from the speaker to the listener. Furthermore, an important aspect of determining the speech intelligibility is the level of background noise.Even though there have been numerous efforts to factually quantify the speech intelligibility, the best method which is widely used is no doubt the Speech Transmission Index (STI) and its derivatives. The speech transmission index is based on the relation between intensity modulations and perceived speech intelligibility in the speaker’s voice. The Modulation Transfer Function (MTF) defines to what amount the modulation is conveyed from the source to the receiver, as the modulation frequency varies from 0.63 to 12.5 Hz. Thus, the modulation transfer function relies on the device properties and the noise produced in the background. Human communication is a continuous waveform with a fundamental frequency which varies from 100 to 400 Hz (The average is about 200 hertz for women and 100 hertz for men).
A recent research have come up with a development that the criminals and suspects of crimes can be identified through their recorded voice during that particular instant of crime with the use of speech intelligibility devices. The voice modulation techniques have found application in investigation, defense as well as entertainment sectors. Since sound engineering is a hopeful sector in the field of science and technology, speech intelligibility gadgets will gain significant traction in the market over the forecast period
