Native_client to inference a model trained in v0.1.1

DeepSpeech
#1

Hello,

I have several DS models trained in version 0.1.1. I used the native_client for that version to inference from my trained models and I maintain the WER statistics for each of my test datasets.

As far as I read thru, current native_client is different from v0.1.1 on 2 main counts:

  1. Streaming ability
  2. Utilization of a different ctc_beam_search_decoder (ctcdecode from parlance)

Since the native_client now uses a different ctc_beam_search_decoder, I would like to inference my test datasets against my previously trained v0.1.1 models using the current native_client that has this feature.

But I see a catch - the current native_client is probably expecting the inferencing graph to be streaming compatible as well?

Can you please confirm if the current native_client is incompatible with models that were trained in 0.1.1?

Is there a commit that supports just #2 above without #1 (streaming ability)? Please share.

thanks,
Buvana

Nope, you will need to retrain. Sorry :confused:
