US-based researchers say AI technology could help voice become a biomarker for some cancers and lesions. Artificial intelligence has found yet another use in healthcare, with a new study saying the technology shows promise in detecting abnormalities of the vocal folds based on the sound of a voice. Published in Frontiers in Digital Health, the US-based researchers fed more 180 standardised speech recordings from 176 people into an AI model that analysed tone, pitch, volume and clarity.
