Abstract

In this paper, the average long-time LPC-based spectrum is evaluated as the parametric representation for speaker recognition. Various factors are discussed and experiments were performed as follows: evaluation of spectrum vs. duration of text-independent utterance, comparison of vocal tract spectra obtained from various languages, comparison between intraand inter-speaker variability in long-time spectrum, and search for a small specially isolated-word vocabulary chosen for Czech language.
