Repeated phrases in the translation

After trying to translate the test file with the trained model, I get the translation with repeated phrases somewhere. Is it because I chose the option: -replace_unk -verbose?

Please advise how can I avoid the repetition.

Thank you so much.

This is a relatively common behaviour when a model is not very confident about the input.
See:

Additionaly, you may try the -block_ngram_repeat flag.

Thank you. You did help me a lot.
