Abstract

Abstract: Speech recognition is one of the developing parts of AI and deep learning. Speech Recognition can be considered a predecessor of Voice recognition. SRE is based on speech recognition and helps send email by speaking and not by typing. Speech recognition involves PLP(Perceptual linear prediction), MFCC(Mel-frequency cepstral coefficients), and many other algorithms, which helps the software to distinguish the specific voice from the surrounding environment, make frequencies audible enough for human ears. DNN uses sound waves as data, to train the software. DNN uses Acoustic model, Pronunciation model, Language model, for speech-to-text, and text-to-speech. Keywords: Speech recognition, sound waves, audio, SMTP, e-mail server.
