Confusion analysis for closed-set recognition of 64 consonant-vowel (CV) sounds, spoken by 18 talkers, is presented. In presence of speech-weighted noise the confusions patterns of the CV syllables categorize into three sets, depending on the consonant. The consonant confusions correlate closely with the high frequency spectra of the consonants while the vowel confusions correlate with the vowel durations and the second formant frequencies.
