Smart Voice Decoder System ECE Microcontroller Project
Smart Voice Decoder system is a good ECE microcontroller project report that is capable of recognizing vowels in human speech. The audio input is sampled through a microphone/amplifier circuit and analyzed in real time using the Mega644 MCU and it also support a simple voice password system where the user can set a sequence of vowels as password to protect a message. You can also Subscribe to FINAL YEAR PROJECT'S by Email for more such projects and seminar.
The project is mainly divided into many section like Serial communication-take user input & display result, Button state machine-for test/demo mode user interface, FWT transform analysis-provide frequency ranges of input waveform, Vowel recognition-analyze vowel spectra and identify, Decode-check whether input vowel sequence is what we expected. Use it only for your reference and study work. The MATLAB results are also shown. Thank to the author and use this report only for your reference work.
