Can you recognize your gender from your child’s voice? Listeners can infer the gender of children up to the age of 5 by jointly inferring their age and physique. -Science Daily

Gender recognition in children’s voices is of particular interest to researchers, as the voices of prepubertal boys and girls are so similar. Adult male and female voices are often quite different acoustically, and gender identity is fairly easy to identify.

Gender perception is much more complicated in children because the gender differences of the speakers can appear before the anatomical differences of the sex-related relationships between the speakers. This may require the listener to consider the speaker’s age when inferring the speaker’s gender, and gender recognition depends on acoustic information that is not strictly related to the anatomical differences between boys and girls. Suggests that there is a possibility.

In Journal of the American Acoustical SocietyResearchers at the University of California, Davis and the University of Texas at Dallas, published by the American Acoustical Society through AIP Publishing, have developed a database of audio samples from children aged 5 to 18 years to investigate two questions. I am reporting. With the voice of a child as they grow up, and how do listeners adapt to huge fluctuations in acoustic patterns between speakers?

The listener assesses the speaker’s gender, age, height, and other physical characteristics, primarily based on the speaker’s voice pitch and voice resonance (formant frequency).

Santiago Barreda of the University of California, Davis said: “Apart from these basic clues, there are other more subtle clues related to behavior and how one” chooses “to speak, rather than relying strictly on the speaker’s anatomy. .. “

Sentence gender identity improved when Barreda and Peter Assmann of the University of Texas at Dallas presented listeners with both syllables and sentences from different speakers. They said this emphasized gender differences and supported the stylistic elements of speech that were better encountered in the text.

They made two other important discoveries. First, listeners can reliably identify the gender of individual children up to the age of five.

“This is before there are anatomical differences between the speakers, and before there are reliable differences in pitch and resonance,” says Valeda. “Based on this, if we can easily identify the gender of an individual child, we conclude that it is not due to anatomy, but due to differences in behavior and speaking style.”

Second, they found that the gender identification of the speaker had to be done along with the age and perhaps physical size identification.

“In essence, the uncertainty in the audio signal is too great to treat age, gender, and size as independent decisions,” he said. “One way to solve this is, for example, whether it’s an independent question about how a 11-year-old boy sounds, not how a man sounds or how an 11-year-old sounds. Is to consider. “

Their study suggests that “gender recognition may depend on subtle behavioral cues rather than anatomical structures.” “In other words, the gender information in a speech can be based primarily on performance, not on the physical differences between male and female speakers. Gender speech inevitably follows the speaker’s anatomy. If there is no reason to reliably identify the sex of a little girl and a boy. “

The nature of gender performance has long been debated for theoretical reasons, and the results of these experiments support this view.
