Deep Speaker Vectors for Semi Text-independent Speaker Verification
TABLE I: EER results on text-dependent task
['[EMPTY]', 'Phrase', 'EER% Cosine', 'EER% LDA', 'EER% PLDA']
The tests are based on three scoring methods: the basic cosine distance, the cosine distance after reducing the dimension to 80 by LDA, and the score provided by PLDA. It can be seen that the d-vector system obtains reasonable performance, however, the results are much worse than those with the i-vector system.
