Patent ID: 11900946
Assignee: ASUSTEK COMPUTER INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 6:
7. An electronic device, comprising:
a sound receiver, configured to collect a plurality of voice signals; and
a processor, electrically connected to the sound receiver and configured for:
extracting voiceprint features of each of the voice signals;
performing a data process on the voiceprint features to convert the voiceprint features into a N-dimensional matrix, where N is an integer greater than or equal to 2;
performing a feature normalization process on the N-dimensional matrix to obtain a plurality of voiceprint data;
classifying the voiceprint data to generate a clustering result; and
finding out a centroid of each cluster according to the clustering result, and registering the voiceprint data adjacent to the centroid;
wherein when the processor is classifying the voiceprint data, the processor further configures to perform:
calculating a number of the clusters and adjacent slopes by an elbow method according to the voiceprint data;
generating the clustering result of classification by a hierarchical clustering algorithm using the calculated number of clusters when the slope changes suddenly; and
generating the clustering result of classification by the hierarchical clustering algorithm without using the calculated number of clusters when the slope does not change suddenly.
