SPEECH-TO-SPEECH TRANSLATION BETWEEN UNTRANSCRIBED UNKNOWN LANGUAGES
Table 2: Our experiment results based on BTEC Japanese-English speech-to-speech translation.
['[BOLD] Model (JA-EN)  [BOLD] Baseline Tacotron with MFCC source', '[BOLD] Model (JA-EN)  [BOLD] Baseline Tacotron with MFCC source', '[BOLD] BLEU -', '[BOLD] METEOR -']
We tried several hyperparameters, including codebook size and time-reduction factor. Our best performance was produced by a codebook of 128 and a time-reduction factor 8 with a score of 15.3 BLEU and 15.3 METEOR.
