i-Vector with sparse representation classification for speaker verification

► Tutorial style introduction to sparse representation classification (SRC) and its applications. ► Investigation on SRC for speaker verification using i-vector from the total variability model. ► Comparative study of SRC systems with different sparseness methods and dictionary composition. ► Development of SRC background dataset selection based on column vector frequency was proposed. ► Results show i-SRC achieves the best performance on NIST 2010 SRE.
