Researchers reveal the area of the brain that controls our voice box, allowing us to alter the pitch of our speech. The insight could pave the way for advancing neuroprosthetics to allow people who can't speak, to express themselves in a naturalistic way.
An auditory-based machine learning algorithm was able to identify children diagnosed with depression and anxiety with 80% accuracy after analyzing recordings of their speech. The algorithm identified eight audio features that signify a higher risk of depression. Of these, a lower pitch of voice, repeatable speech inflections and a higher pitch response to surprise stimuli, were more indicative of depression. Researchers hope to develop a smartphone app that records and analyzes speech immediately, helping to better detect children at risk of internalizing disorders.

However, researchers found no evidence of a link between vocal pitch or perceptions of facial attractiveness, health, or femininity.
