The most successful systems in previous comparative studies on speaker age recognition used short-term cepstral features modeled with Gaussian Mixture Models (GMMs) or applied multiple phone recognizers trained with the data of speakers of the respective class. Acoustic analyses, however, indicate that certain features such as pitch extracted from a longer span of speech correlate clearly with ...

This study examined two possible sources of individual differences in crosslanguage speech perception, the capacity to phonologically encode speech and short-term memory span. Phonological coding was defined as the ability to encode non-native contrasts as distinct phonemes based on representations in long-term memory. Short-term memory was defined as a fixed capacity regulating the extent of e...
