Peer-reviewed literature on the effects of sound and music on babies ranging from the prenatal period to the postnatal period, called the perinatal period moving forward, is vast. Substantial research has been directed towards the neural connections they make with sound, musical therapy, audio learning, and much more. The primary focus of this thesis was to review the current literature on how the father's voice affects the fetus during the perinatal period. During the preliminary research of the topic, the process faced an immediate problem as this concept had very little substantial sources. The number of relevant articles or documents with the term “father” in the title can be counted on one hand. In some cases, research that explored the father’s voice did so only as a supporting statistic or comparison to the main goal of exploring the mother’s voice. The mother’s voice has been prioritized as a research topic because of the immediate physical connection between the mother and the child throughout the entire pregnancy. The third semester of pregnancy is often a period of study since what the mother senses, says or does will somehow translate into an experience for the child’s developing brain. On the other hand, the father’s voice has been considered an environmental sound, a position justified by some researchers due to phenomena such as differing levels of fetal attention and observed “preference” of a newborn. The scarcity of research regarding the father’s voice, or the voice of a non-parental male, can be explained in several ways. These include the father’s potential absence due to work, inherited ideologies and biases against active parenting for the father, parental roles, and their unwillingness to utilize infant-directed speech and singing for psychological reasons, during the perinatal period, compared to that of the mother. Researching ways to deepen the relationship between the father and baby during the perinatal period, along with developing new biotechnologies for different kinds of evaluative tests, will help advance the subject matter of how the father’s voice impacts a baby to a larger scale.
