Espnet: rnn-t streaming decoding

[lyjzsyzlt]

Is there an implementation of rnn-t streaming decoding?

Hi,

Streaming RNN-T is not available in espnet. Some work was done internally but it was put in standby. I can't really say when we'll work on it again as there are a lot of other works related to RNN-T/T-T we have to finish.

Thank you for your reply! I found that rnn-t beam search decoding was very slow. Will you optimize this next?

Yes, I'll propose different beam search algorithms which significantly improve decoding time. It should be available really soon.
