Researchers have stated that 'closely spaced' line spectral pairs (LSP's) tend to mark formants. [J. R. Crosmer and T. P. Barnwell, Proceedings of the ICASSP 85, Tampa, FL, 26-29 Mar. 1985 (IEEE, New York, 1985), Vol. 2, pp. 240-243.] None of the studies quantified the term 'closely spaced' and gave little or no experimental evidence to support the statement. This paper compares visually determined formant areas from digital spectrograms and overlaid LSP tracks. Incremental threshold values using three different methods for the test of 'closeness' were used to test and quantify that correlation experimentally across one syllable for many talkers and across many /hVd/ syllables for a male and female talker. Results show that the closer the LSP's the more probable they are to overlay a formant, that most false hits tend to occur in low energy (i.e., consonantal) areas, and that LSP's track F1 and F2 better than F3 and F4. Incidental evidence tends to counter Crosmer and Barnwell's claim that the closed glottis odd LSP coefficient will correspond approximately to the formant center frequency. [ABSTRACT FROM AUTHOR] |
