How to reproduce the issue ? (This is for errors. Please share the command and the detailed log here)

  1. install riva quickstart, download all dependencies etc.
  2. in the config.sh script- set the following for the asr model-service_enabled_asr=true ,
    asr_language_code=(“ja-JP”)
    asr_acoustic_model=(“conformer”)
    asr_acoustic_model_variant=(“unified”) OR leave it “” empty

Run init and start scripts. In order to connect to the ASR service, use the sample app provided:

Ensure correct setup of env.txt file, correct server IP, language settings and interim_results set to true.

Issue:
The interim transcripts don’t appear in the server logs OR on the client side of the sample application. However, when I switch to the english language, I am able to see the interim results. Of course, I am able to see the final transcripts correctly in both cases (EN and JP)
