Frequency Analysis Of Speech Signals For Devanagari Script And Numerals
Vidhu Gupta, Neeraj Kumar Jain · IOSR Journal of Electronics and Communication Engineering · 2016
This paper comprehends the analysis of frequency of spoken Devnagari script and Numerals from the primitive speech signals.Devnagari vowels and numerals play essential role in pronunciation of any word or counting.Particular vowel & number is dividing as starting, middle and end according to the time of occurrences in the word.The Devnagari script contains 12-vowels and 34-consonants and they are pre-owned in some Indian language like Hindi and 10 numerals (0-9) are worn in mathematics.Sound samples from multiple speakers were applied to obtain different features.Starting processing of data, that is normalizing and time-slicing was done using an amalgamation of Simulink and MATLAB.Later on, the same engines were used for calculation of fourier descriptions and correlations.The correlation permits comparison of the identical words or numeral uttered by the identical and different speakers.Hence the frequency has been calculated in statistical manner and produced a table among amplitude and frequencies.Standard deviation and mean can also be used in implementation of a voice-driven help setup at call centres of commercial organizations running in India and other foreign areas.
