Phone-aware Neural Language Identification
Table 4: Results of phone-aware LID on four languages (Assamese, Georgian, Bengali and Turkish).
['Phonetic RNN', 'LID RNN', '[ITALIC] Cavg Fr.', '[ITALIC] Cavg Utt.', 'EER% Fr.', 'EER% Utt.']
The final experiment tests the LID performance on all the four languages. The baseline system is the RNN LID model trained with the data of the four languages, denoted by AGBT-LID. For the phone-aware system, the AG-MLT is used to produce the phonetic feature, and the g function is used as the feature receiver. Again, the performance is greatly improved by involving the phonetic feature.
