Abstract: 1 MATURING TEMPORAL BONES AS NON-NEURAL SITES FOR TRANSFORMING THE SPEECH SIGNAL DURING LANGUAGE DEVELOPMENT Developmental events in the temporal bones shift the pattern of a given speech sound’s acoustic profile through the time children are mapping linguistic sound systems. Before age 5 years, frequency information in vowels is differentially accessible through the years children are acquiring the sound systems of their native language(s). To model the acoustic effects caused by developing temporal bones, data collected to elicit steady-state vowels from adult native speakers of English and Diné were modified to reflect the form of children’s hearing sensitivities at different ages based on patterns established in the psychoacoustic literature. It was assumed, based on the work of psychacousticians (e.g., Werner, Fay & Popper 2012; and Werner & Marean 1996), that the effects caused by immature temporal bones were conductive immaturities, and the age-sensitive filters were constructed based on psychoacoustic research into the hearing of infants and children. Data were partitioned by language, sex, and individual vowels and compared for points of similarity and difference in the way information in vowels is filtered because of the constraints imposed by the immaturity of the temporal bones.

TL;DR: The main themes and findings from this research are consistent with those found for adult age estimation (Garvin and Passalacqua 2012), however, the results of the various methods used are likely still accurate for sex estimation as mentioned in this paper.
Abstract: Understanding the preferences and methods being employed for sex estimation, as well as how results are reported, is the first step towards standardization. The main themes and findings from this research are consistent with those found for adult age estimation (Garvin and Passalacqua 2012). There is considerable variation present; however, the results of the various methods used are likely still accurate for sex estimation. The next step is recognizing the choices being made and our preferences to promote further discussions and then work towards standardization within our field. Experience
