Speech to text Model training

Does OpenNMT support Connectionist temporal classification (CTC) with RNN?
If it supports then how to use it?

No it does not. You might want to have a look at a more speech oriented toolkit (deepspeech.pytorch?).

which one is better OpenNMT-py speech to text or deepspeech?

Wouldn’t know for sure, and it probably depends on your task. Maybe ask @da03 who worked on the speech implementation in OpenNMT-py.
(Still, one has “Neural Machine Translation” in its name, the other “Speech”, might be a clue.)

Thanks Francois.
I will look into this.
