manage to distinguish twins using four different models, namely, face recognition, ear recognition, voice recognition and lip … movement recognition. Their results show that voice recognition has the best performance in twin recognition with 100% accuracy …. This is much higher than that of face recognition and ear recognition (with 58% and 53% respectively); and lip movement …
