Improving of clustering results for speech data by visual approach

Visual Approaches for Exploratory Data Analysis: A Survey of the Visual Assessment of Clustering Tendency (VAT) Family of Algorithms

“…Speech Data Processing A series of papers by Prasad, Nennuri, Reddy, and Basha [99]- [101] used VAT, iVAT, and SpecVAT with the GMM and cosine distance matrix for the application of speaker classification. They developed new techniques, GMMVAT and cosine-based VAT (cVAT), for clustering speech utterances by the same speaker.…”
