A memory storing computer readable instructions for causing a processor associated with a mega speaker identification (ID) system to instantiate functions including an audio segmentation and classification function receiving general audio data (GAD) and generating segments, a feature extraction function receiving the segments and extracting features based on mel-frequency cepstral coefficients (MFCC) therefrom, a learning and clustering function receiving the extracted features and reclassifying segments, when required, based on the extracted features, a matching and labeling function assigning a speaker ID to speech signals within the GAD, and a database function for correlating the assigned speaker ID to the respective speech signals within the GAD. The audio segmentation and classification function can assign each segment to one of N audio signal classes including silence, single speaker speech, music, environmental noise, multiple speaker's speech, simultaneous speech and music, and speech and noise. A mega speaker identification (ID) system and corresponding method are also described. |
