Comparing speech recognition for adults and children

Abstract

This paper presents initial studies of the per-formance of a speech recogniser on children's speech when trained on children or adults. A connected-digits recogniser was used for this purpose. The individual digit accuracy among the children is correlated to some features of the child, such as age, gender, fundamental frequency and height. A strong correlation be-tween age and accuracy was found. The accu-racy was also found to be lower for child rec-ognition than for adult recognition, even though the recognisers were trained on the cor-rect class of speakers.
