Efficient voice activity detection algorithm using long-term speech information

Joint Dictionary Learning-based Non-Negative Matrix Factorization for Voice Conversion (TBME 2016)

ASPP: Binaural Speech Enhancement with Atomic Speech Presence Probability Estimation

Classifying AI Synthesised Voice and Human Voice using Machine Learning by Spectral and Cepstral Analysis. Also classified different TTS(Text-to-Speech) engines for different AI synthesized Voice. Published Paper for the whole art of work. Link Given below.

A real-time analyzer to detect normal speech/abusive speech/noise

Classifying sound signals as Links, Midden or Rechts using features computed using a Mel-Frequency filterbank, summing the power of the frequency-domain in the relevant filters. Dynamic Time Warping is used to find proper alignment between the unknown word and several labelled exemplars per word we are looking for. Then, k nearest neighbours tel…

wSTMI: A speech intelligibility prediction algorithm for noisy and processed speech

MATLAB implementation of the Speech Transmission Index for Public Address (STIPA) method for evaluating the speech transmission quality.

Python and Matlab code for segmentation of field recordings

基于对刚生成网络的语音降噪

This project is written by MATLAB R2020b for speech watermarking suitable for content authentication. Firstly, 4 folders are made by names of "original", "watermark", "extract" and "attack". Then 4 wav files are copied to "original" folder. Finally "final_1.m" can be run.
