“…In that study, pulsed stimuli were more effective at eliciting an HR acceleration in sleeping infants than were continuous stimuli. More recently, Byrne, Miller, and Hondas (1994) examined the effect of temporal pattern on the cardiac OR in 3-and 6-month-old infants. Both age groups responded with a larger and more sustained HR deceleration to pulsed than to continuous stimuli.…”

The purpose of this study was to determine whether temporal pattern and/or spectral complexity were important stimulus parameters for eliciting a cardiac orienting reflex (OR) in low-risk human fetuses. Each of28 term fetuses was exposed to four sounds formed from the four different combinations of temporal pattern (pulsed, continuous) and spectral complexity (sine wave, /3/). The fetal cardiac electrical signal was captured transabdominally at a rate of 1024Hz, and fetal R-waves were extracted by using adaptive signal-processing techniques. We found that pulsed sounds elicited a significantly greater decrease in heart rate (HR) than did continuous sounds. However, the HR response was relatively unaffected by spectral complexity. For the pure tone and the phoneme used in this study, our results indicate that temporal characteristics were more effective at eliciting a cardiac OR in human fetuses than was spectral complexity.Successful word recognition involves the perception and discrimination of different sounds, recall of a cognitive representation of specific sounds, and segmentation of speech into the correct sequence of words (Jusczyk, 1993). Although these skills are acquired at different times during development (Jusczyk, 1993), it appears that newborn infants already possess remarkable discriminatory capabilities: Two-day-old infants can discriminate between stop consonant contrasts (e.g., ba vs. da) and between following vowel contrasts (e.g., ba vs. bi; Bertoncini, Bijeljac-Babic, Blumstein, & Mehler, 1987), and by 4 days postnatal age, infants can encode sufficiently detailed information to detect the addition of a new syllable to a set of familiar ones

“…Jusczyk et al found that 2-montholds discriminated semivowels (/w/ and /y/) based on formant transition differences [82]. Byrne et al found that 3-and 6month-olds can discriminate interphonemeic transitions inside a diphthong [83]. Nasals (/ma/ and /na/) can be distinguished by formant transitions [78], [84].…”

Speech feature extraction is critical for ASR systems. Such successful features as MFCC and PLP use filterbank techniques to model log-scaled speech perception but fail to model the adaptation of human speech perception by hearing experiences. Infant perception that is adapted by hearing speech without text may cause permanent brain state modifications (engrams) that serve as a physical fundamental basis for lifetime speech perception formation. This realization motivates us to propose to model such an unsupervised adaptation process, where adaptation denotes perception that is affected or changed by the history of experiences, with the Dirichlet Process Gaussian Mixture Model (DPGMM) and the DPGMM-RNN hybrid model to extract perceptual features to improve ASR. Our proposed features extend MFCC features with posteriorgrams extracted from the DPGMM algorithm or the DPGMM-RNN hybrid model. Our analysis shows that the DPGMM and DPGMM-RNN model perplexities agree with infant auditory perplexity to support that the proposed features are perceptual. Our ASR results verify the effectiveness of the proposed unsupervised features in such tasks as LVCSR on WSJ and ASR on noisy low-resource telephone conversations, compared with the supervised bottleneck features from Kaldi in ASR performance.
