Synthetic Data for Neural Machine Translation of Spoken-Dialects
Table 4: Translation performances in BLEU for Large Scale NMT with Generated data
['System', 'LEV-ENG-Test', 'LEV-MSA-ENG', 'NIST08']
The performance of the system with the synthetic data is just 0.3 BLEU less than the oracle score on the human translated MSA (27.91 vs 28.20). Moreover, the addition of the synthetic data did not negatively affect the MSA NIST08 test sets as well; this simply enables us to have a single system to serve both written and spoken variants.
