  1. 1. Detection of Human Emotion from Noise Speech

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Sai Chandra Sekhar Reddy Nallamilli; Nihanth Kandi; [2020]
    Keywords : Neural Network; Activation Function; Fast Fourier Transform; Karhunen-Loeve Transform; speech enhancement; filtering; Wavelet Transform; Speech preprocessing; signal to noise ratio; shallow neural network;

    Abstract : Detection of a human emotion from human speech is always a challenging task. Factors like intonation, pitch, and loudness of signal vary from different human voice. So, it's important to know the exact pitch, intonation and loudness of a speech for making it a challenging task for detection. READ MORE
