Abstract :
A way to identify people by voice is discussed. A speaker´s spectral information represented by line spectrum pair (LSP) frequencies is used to describe characteristics of the speaker´s utterance and the VQ (vector quantization) method is used to model the spectral distribution of each speaker. Some easily computed distances (Euclidean distance, weighted distance by F-ratio, and hard-limited distance) are used to measure the discrimination among speakers
