| Abstract(in English) | We propose a method for quantizing speaker identification accuracy for speech communication services. We focused on a voice quality of speech as one of the quality factors of wideband speech and considered the following four points; 1) reducing fluctuation in speaker identification accuracy over time, 2) using many speakers in a speaker identification test, 3) reducing the effects of factors unrelated to the voice quality, 4) considering speaker identification accuracy for speech that is not executed speech processing in communication service. Finally, we quantized the effects of low/high bandwidth limiting on speaker identification accuracy using our method. The results show that limiting high bandwidth to less than 7 kHz and limiting low bandwidth to more than 100 Hz degrades speaker identification accuracy. |
