This thesis aims to perform categorized recognition of 5 speech
emotions as represented by joy, grief, anger, fear and surprise
by means of algorithm with the combination of HMM and
SOFMNN models so as to apply speech emotion recognition
methods presented by integrated HMM/SOFMNN model to
the platform of intelligent household robot. In this way, robot
can recognize emotional information as contained in the
human speech signals for friendly interaction with human
beings, and eventually satisfactory performance and effect are
realized.
