The ability of human fetuses to recognize their own mother's voice was examined. Sixty term fetuses were assigned to one of two conditions during which they were exposed to a tape recording of their mother or a female stranger reading a passage. Voice stimuli were delivered through a loudspeaker held approximately 10 cm above the maternal abdomen and played at an average of 95 dB SPL. Each condition consisted of three 2-min periods: no stimulus, voice (mother or stranger), and no stimulus…

Fetal sensitivity to properties of maternal speech and language

Fetal speech and language abilities were examined in 104 low-risk fetuses at 33–41 weeks gestational age using a familiarization/novelty paradigm. Fetuses were familiarized with a tape recording of

Fetuses respond to father's voice but prefer mother's voice after birth.

Newborns showed a preference for their mother's but not their father's voice, and the characteristics of voice stimuli that capture fetal attention and elicit a response are yet to be identified.

Onset and maturation of fetal heart rate response to the mother’s voice over late gestation.

A relatively long latency and sustained duration of the heart rate response suggest auditory processing, the formation of neural networks, above the level of the brainstem.

The Effect of Experience on Recognition of Mother’s Voice in Preterm Infants

It is concluded that the preterm infants can recall and differentiate their mothers’ voice from the voice of a stranger and an opportunity can be provided during the developmental care for the infants to hear their mother’s voice.

The Impact of Maternal Voice on the Fetus: A Systematic Review

The role of maternal voice for prenatal human bonding needs to be discussed according to different maternity conditions such as surrogate mothers and a new paradigm is suggested; the focus of research should be on maternal-fetal interaction under the presence of maternalVoice.

Estimated cardiac vagal tone predicts fetal responses to mother's and stranger's voices.

Heart rate responses of 84 near-term fetuses to recorded female voices were examined and vagal tone plays a moderating role in the cardiac responses of termfetuses to familiar and unfamiliar stimuli.

Chapter 2 Prenatal Experience with the Maternal Voice

Fetal auditory experience with the mother’s voice begins around 24 weeks after conception, the maternal voice is potentially a rich source of multimodal stimulation and information, and for favorable postnatal development, the role that is played by very early exposure to the maternalvoice is not yet understood.

Fetal Response to Live and Recorded Maternal Speech

This is the first study to show differences in the fetal cardiac response to a passage spoken live compared to a recording of the passage following a lengthy history of controlled fetal exposure to the multimodal characteristics of maternal speech.



Newborn and fetal response to maternal voice

Fetuses evidenced no ability to discriminate between their mother's and a stranger's voice played to them via a loudspeaker on the abdomen but did discriminate between the mother's voice produced by her speaking.

Prenatal discrimination of a male and a female voice uttering the same sentence

Using a habituation/dishabituation procedure, near-term foetuses (36-39 weeks gestational age) were tested in a low variability HR state, to examine whether they could discriminate between a male and

Unfamiliar voice discrimination for short stimuli in newborns

In order to determine the minimal information required for newborns to discriminate unfamiliar voices two experiments were performed using the presentation of single disyllabic words uttered by male

Influences on infant speech processing: toward a new synthesis.

This work offers an integrated transactional framework based on the notion of a specialized perceptual-motor system that has evolved to serve human speech, but which functions in concert with other developing abilities.

Human Fetal Responses to Sound as a Function of Stimulus Intensity

It is concluded that fetal response varies as a function of stimulus intensity and that the threshold for response to an air‐borne pink noise is between 100‐105 dB.
