  ABSTRACT: Speaker identification traditionally employs technologies of MRCC and LPC, and most of the proven existing technologies are strictly text-dependent. New technologies are text independent. Whatever technologies are used for speaker identification their performance degrades if the list of the speakers stored for identification grows. Therefore, if other pertinent parameters are added to the extracted data from the speaker's speech, speaker identification will get enhanced. This research aims to enhance speaker identification by adding a new parameter namely speaker's speaking speed to the extracted data to enhance the accuracy of the speaker identification. This paper has manually determined the speaking speed from many recorded conversations, which were saved in computer by Bluetooth. A reputed software Praat was used to watch sound graphics and to make calculations. The Praat's calculation confirm that our study can be used to make an algorithm to automatically determine correct speaker speed.

  ABSTRACT: In this paper it is reported that definite relationships exist between the number of syllables in any Urdu text and the long vowels, short vowels and consonants these syllables contain. This information is useful in preparing an automatic algorithm to calculate speaking speed of a speaker. For every 100 syllables there are 38 short vowels, 58 long vowels and 3% of diphthongs. This percentage holds good for almost any number of syllables greater then about 50. The consonants have also been counted in syllables and found to be 135% of syllables. For every 100 syllables there are about 135 consonants, and this percentage holds true for syllables greater then about 50 syllables. These numbers help us calculate the probability of the long, short vowels and the consonants in any Urdu text, which can in turn be used in an algorithm to automatically calculate the speaking speed.
