Speaker verification in score-ageing-quality classification space

Andrzej Drygajlo, Finnian Paul Kelly

A challenge in automatic speaker verification is to create a system that is robust to the effects of vocal ageing. To observe the ageing effect, a speaker's voice must be analysed over a period of time, over which, variation in the quality of the voice sam ...
