something more serious鈥攍ike a cyst or a tumour. Although people鈥檚 voices
can be very different, scientists at UMIST in Manchester and the city鈥檚 Christie
Hospital, Withington, have trained a neural network program to recognise the
characteristics of a healthy voice. If a lump forms on the larynx, the voice鈥檚
characteristics are different鈥攖hough the change may not be obvious to the
ear. 鈥淲hat we鈥檝e got is the makings of a screening tool,鈥� says Tim Ritchings of
UMIST.
