Audio feature extraction technique based on MFCC extracts characteristics from identical speech to once that are preowned by human for hearing speech whereas parallely all other information's are neglected.
MFCC exhibits real cepstral of a windowed short time signal which is evolved from fast Fourier transform (FFT). the most extensive and prominent way to extract spectral features is determining Mel-frequency cepstral coefficients (MFCC).MFCC used in speech recognition depend on frequency domain using Mel scale that intern depends on human ear scale. The objective of speech recognition area is to make changes and develop a system for speech input to a machine based on progress of statistic modeling of speech. The conversion of speech signal to words in a orderly manner by means of algorithm applied as a machine program is termed as speech recognition. The Zigbee technology is broadly adopted for bulk and fast data transmission over a dedicated channel. As Zigbee is the upcoming technology in wireless field, we had tried to demonstrate its way of functionality and various aspects like kinds, advantages and disadvantages using a small application of controlling the any kind of electronic devices and machines.
Zigbee is the set of specs built around the IEEE802.15.4 wireless protocol. ZigBee is a wireless technology developed as an open global standard to address the unique needs of low-cost, low-power, wireless sensor networks. Speech recognition is the process of recognizing the spoken word to take necessary actionsĪccordingly. Whether due to technological curiosity to build machines that mimic humans or desire to automate work with machine, research in speech recognition as a first step towards human- machine communication. Speech is the primary and most convenient means of communication between humans. In this project we use a speech recognition system which recognizes the spoken command by the user and compares it with already existing database and also Zigbee wireless communication between two systems. Also developments in Speech synthesis technology for various languages have already taken place. In the last few years however the use of text-to-speech conversion technology has grown far beyond the disabled community to become a major adjunct to the rapidly growing use of digital voice storage for voice mail and voice response systems. It is widely used in audio reading devices for blind people now a days. Text-to-speech (TTS) convention transforms linguistic information stored as data or text into speech. Speech- to-text conversion (STT) system is widely used in many application areas. The speech is primary mode of communication among human being and also the most natural and efficient form of exchanging information among human in speech. Human interact with each other in several ways such as facial expression, eye contact, gesture, mainly speech. Keywords: Speech Recognition, Communication, Algorithm The objective of this paper we use a speech recognition system which recognizes the spoken command by the user and compares it with already existing database and also Zigbee wireless communication between two systems. However, the transfer of speech into written language in real time requires special techniques as it must be very fast and almost 100% correct to be understandable. In this system, we are going to develop an speech-to-text engine. However, with modern processes, algorithms, and methods we can process speech signals easily and recognize the text. This paper concludes with the decision on future direction for developing technique in human computer interface system in mother tongue and it also discusses the various techniques used in each step of a speech recognition process and attempts to analyze an approach for designing an efficient system for speech recognition. A comparative study of different technique is done as per stages. This paper basically gives an overview of major technological perspective and appreciation of the fundamental progress of speech to text conversion and also gives complete set of speech to text conversion based on Zigbee wireless communication. The communication among human computer interaction is called human computer interface.
