Short-term Spectral Slope Measures and their Sensitivity to Speaker, Vowel Identity and Prominence

Original language description

This study examines ten methods of measuring short-term spectral slope with the primary aim of quantifying vowel prominence. A highly controlled dataset consisting of 45 pseudowords with varied placement of prominent vowel read by 12 speakers was used. The investigated methods included Hammarberg index, ?-measure, linear regression, di?erences of spectral energies in separate frequency bands, di?erence between amplitudes of the ?rst two formants and spectral emphasis. All of the methods showed substantial sensitivity to speaker and vowel identity in particular. Nevertheless, most of the methods were also able to discriminate among prominent and non-prominent realizations of the vowels. The di?erence between sums of energy in two adjacent frequency bands separated by a ?oating pivot locked to the value of the second formant proved to be the most successful measure. On the contrary, linear regression of the spectrum performed worst. Also, exclusion of the fundamental frequency band decre
