The team spoke to participants with and without comorbid AD/MDD and recorded them using a secure telehealth platform. The participants were given a semantic verbal fluency test, in which they were required to name as many animals as possible within a time limit. The team extracted acoustic and phonemic features from the recordings and applied machine learning technique to distinguish subjects with and without comorbid AD/MDD. The results confirmed that a one-minute semantic VFT can be reliably used to screen for AD/MDD.

The researchers analyzed vowels in interjections from 131 languages, comparing them with nearly 500 vowels from vocalizations produced in joyful, painful, or disgusting contexts. Each of the three emotions yielded consistent and distinct vowel signatures across cultures in vocalizations. American Institute of Physics (AIP)
