Abstract |
The basic idea of the presented approach is to evaluate a spectral characteristics corresponding to the anatomy of the speaker´s vocal tract independently of the actually pronounced phoneme. The procedure for determining the speaker-specific average spectrum is based on the LPC approach. Experimental results have shown an evolution in a long-time spectrum with respect to the duration of text independent utterance. This was compared with a representative set of chosen isolated words using a long-time spectrum variability between and within speakers. The evaluated method is suitable for both text-dependent and text-independent speech signal processing. |
