Abstract
U okviru ovog rada predstavljen je način rješavanja zadatka verifikacije govornika primjenom dubokih neuronskih mreža. Prvotno su definirani zadaci identifikacije i verifikacije govornika te su predstavljena moderna rješenja za rješavanje tih problema, pri čemu se ističu rješenja ostvarena korištenjem konvolucijske i sijamske neuronske mreže. Ovim radom zadatak verifikacije govornika se rješava treniranjem sijamske neuronske mreže na temelju logaritamskih Mel spektrograma stvorenih iz zvučnih zapisa GRID skupa podataka. Primjenom augmentacija Gaussovog šuma i amplitudne augmentacije spektrograma na trening skupu podataka treniraju se nove mreže kojima se procjenjuje utjecaj augmentacija na rad verifikacije govornika. S ciljem povećanja raznolikosti skupa podataka, stvoren je vlastiti skup podataka s 12 različitih govornika. Korištenje tog skupa i procesom prijenosnog učenja na temelju već istreniranih mreža na GRID skupu podataka dobivene su nove mreže. Nadalje, izrađena je aplikacija koja omogućuje primjenu istreniranih mreža za verifikaciju govornika u stvarnom okruženju. U konačnici, sve izgrađene mrže su detaljno evaluirane na testnom skupu podataka.
Abstract (english)
This master’s thesis presents a method for solving the speaker verification task by using deep neural networks. Firstly, the tasks of speaker identification and verification are defined, followed by presenting modern solutions for these problems, with a focus on solutions achieved using Convolutional Neural Networks and Siamese Neural Networks. In this paper, the speaker verification task is solved by training a Siamese Neural Network based on log-Mel spectrograms created on audio recordings of the GRID dataset. By applying data augmentations on training dataset, such as Gaussian noise and amplitude augmentation of spectrograms, new networks are trained to evaluate the impact of these augmentations on speaker verification performance. To increase the diversity of the GRID dataset, a custom dataset with 12 different speakers was created. Using this dataset and a transfer learning process based on networks already trained on the GRID dataset, new networks were trained. Furthermore, a desktop application was developed that enables the use of trained networks for speaker verification in real-world environment. In the end, all constructed networks were thoroughly evaluated on the test dataset.
