چکیده

For the past five decades there has been a substantial increase in the development of computer applications based on the STFT (Short-Time Fourier Transform) spectrograms. Amongst others, a relevant example of this kind of implementation is speech analysis. Indeed, if the audio signal is correctly filtered, it is possible to use STFT spectrogram techniques to recognize speech. This work investigates the use of STFT spectrograms in speech recognition, using the voice deal function of mobile phones. The voice recognition rate obtained is then compared with that obtained with some commercially available mobile phones. The high recognition rate obtained validates the use of a STFT spectrogram methodology in speech recognition and certainly encourages further work to be carried out. Key-Words: STFT, Spectrogram, Voice Recognition, Correlation.
