“…It is indeed important to note that syllable intonation, duration and syllable formants due to the speakers' voice characteristics varied within a phonetic category and that these variations were easily discernible by adults. Neonates are able to perceive such variations: they can discriminate their mother's voice from another [5,6] or between two strangers' voices [7] and electrophysiological response to a voice change has been recorded [8]. Thus, only a network able to extract the phonetic category notwithstanding perceptible irrelevant acoustical variations can elicit such a mismatch response in the different speaker trials.…”

At least two fundamental properties should be present in a network computing a phonetic representation: categorical perception and normalization across different utterances. Normalization processes were studied at birth by recording high density evoked potentials to strings of syllables in sleeping neonates. We compared the response to a change of phoneme when irrelevant speaker variation was present or absent. A mismatch response was recorded at the same latency in both cases, suggesting that relevant phonetic information was extracted from the irrelevant variation. Combined with our previous work showing that the mismatch response is sensitive to categorical perception in infants, this result suggests that a phonetic network like that of adults, is already present in the infant brain. Furthermore, ef®cient phonetic processing does not require attention.

“…Studies using measures of sucking preference or heart rate show that one-month-old infants prefer their mother's voice to voices from other persons (Mehler et al 1978). This ability is even present in newborn babies (DeCasper & Fifer 1980) and extends to the father's voice (Ockleford et al 1988). Recent measures in foetuses suggest that his ability is even present before birth (Kisilevsky et al 2003).…”

Humans share with non-human primates a number of voice perception abilities of crucial importance in social interactions, such as the ability to identify a conspecific individual from its vocalizations. Speech perception is likely to have evolved in our ancestors on the basis of pre-existing neural mechanisms involved in extracting behaviourally relevant information from conspecific vocalizations (CVs). Studying the neural bases of voice perception in primates thus not only has the potential to shed light on cerebral mechanisms that may be-unlike those involved in speech perception-directly homologous between species, but also has direct implications for our understanding of how speech appeared in humans. In this comparative review, we focus on behavioural and neurobiological evidence relative to two issues central to voice perception in human and non-human primates: (i) are CVs 'special', i.e. are they analysed using dedicated cerebral mechanisms not used for other sound categories, and (ii) to what extent and using what neural mechanisms do primates identify conspecific individuals from their vocalizations?

“…Hepper and Shahidullah, 1994;Abdala and Keefe, 2012), and effects of very early auditory categorization have also been found in utero: a number of experiments have shown that third-trimester fetuses' auditory experience can influence their postnatal auditory preferences: newborns tend to quiet in response to their mothers' voice (and touch), Marx and Nagy (2015), and they also tend to prefer their mother's voice over other female's voice (cf. Mehler et al, 1978;DeCasper and Fifer, 1980;Fifer, 1981;Querleu et al, 1984;Spence and DeCasper, 1987;Ockleford et al, 1988;Hepper et al, 1993) 1 . Besides, as reported by DeCasper and Spence (1986), newborns also tend to be more reinforced by the audition of speech passages they heard in utero over passages they were not exposed to (and they can remember them for over a month; Granier-Deferre et al, 2011).…”
