Acoustic characteristics of speech signals differ with gender due to physiological differences of the glottis and the vocal tract. Previous research [1] showed that adding the voice-source related measures H1*-H2* and H1*-A3* improved gender classification accuracy compared to using only the fundamental frequency (F0) and formant frequencies. Hi* refers to the i-th source spectral harmonic magnitude, and Ai* refers to the magnitude of the source spectrum at the i-th formant. In this paper, three other voice source related measures: CPP, HNR and H2*-H4* are used in gender classification of children's voices. CPP refers to the Cepstral Peak Prominence, HNR refers to the harmonic-to-noise ratio, and H2*-H4* refers to the difference between the 2nd and the 4th source spectral harmonic magnitudes. Results show that using these three features improves gender classification accuracy compared with [1].
