The purpose of the speech is communication. The area of speech processing is just developing, and shows the tremendous potentialities for widespread use in the future. In this project we have processed the speech signal with the help of the DIGITAL SIGNAL PROCESSING techniques. The speech signal is given as the input will be verified using speech recognition technique using matlab. We have used Mel Frequency Cepstral Coefficient (MFCC) along with Vector Quantization (VQLBG) and Euclidean Distance to identify different characters. Based on the results, data was send to Parallel Printer Port of the computer & using relay different devices will be controlled.

.已知某炉温控制系统，要求温度保持在600℃恒定，针对该控制系统有以下控制经验： （1）若炉温低于600℃，则升压，低的越多升压越高； （2）若炉温高于600℃，则降压，高得越多降压越低； （3）若炉温等于600℃，则保持电压不变。 设模糊控制器为一维控制器，输入语言变量为误差，输出为控制电压。输入输出变量的量化等级为7级，取5个模糊集，试设计隶属度函数误差变化划分表，控制电压变化划分表和模糊控制规则表。 (Known for a temperature control system that requires a constant temperature is maintained at 600 ℃, the following control experience for the control system: (1) If the furnace temperature is below 600 ℃, the step-up, the more the higher the lower the boost (2) if the furnace temperature is higher than 600 ℃, the blood pressure, high blood pressure, the lower the more (3) If the furnace temperature is equal to 600 ℃, then keep the voltage constant. Set of fuzzy controller for one-dimensional controller, input linguistic variables for error, the output control voltage. Input and output variables of quantization levels for seven, take five fuzzy sets, membership function test design error variance divided table, partition table and the control voltage variation fuzzy control rule table.)
