We present the analysis performed over eleven speakers (five women and 6 men) in order to obtain the most important parameters as far as speaker identity is concerned. Parameters that have been studi studied are F0, six formants, five bandwidths ed and four source parameters. Feature selection is based on linear discriminant analysis. Results show that the most relevant parameter is F0, followed by formant frequencies and open quotient.
