The horizontal line represents a 100% perfect match. The diagram shows the difference of both voice profiles. The evaluation resulted in a match of less than 50% and so both voices are not identical.



Identical voices

Voice 3 [1.658 KB]
Voice 4 [1.734 KB]


 


The difference of both voice profiles results in a minimum deviation from the horizontal. The matching factor of the two voice samples amounted to over 90%.



Imitated voices

Voice 5 [636 KB]
Voice 6 [588 KB]


 


Here we compare an original voice and the voice of an imitator. For the human hearing both voices sound very similar. However, the evaluation of the voice characteristics results in a by far larger deviation, than our hearing senses this. The matching factor of the two voice samples is well below 50%, indicating non identical speakers.
