In seminars, students are expected to participate actively. In this study, we would like to create a system that can measure the activity of students in the seminar. Speaker identification is performed using a convolutional neural network to create a system. The input data was recorded spectrogram images created by fast Fourier transform by dividing the recorded speech of the seminar every one second. The classification was done in seven categories of 6 people and ambient sound. The correct answer rate was 56.7%. As a result of extracting speakers from six people, the correct answer rate was 76.3% at the maximum and 63.1% at the minimum. From the results, we propose a method to improve the correct answer rate of speaker diarization. |
