I’m doing audio to text transcription through the StreamingRecognize API, I have a lot of latency, I want to use chunks of 160ms size to improve latency. Is it possible to configure this from the riva quick start scripts or should I build new pipelines with riva-build?

HI @nharo

Thanks for your interest in Riva

Apologies, unfortunately, we won’t be able to configure chuck size from quick start, it can only be tweaked manually using `--chunk_size` flag in riva-build and deploy process

Thanks

I am trying audio to text transcription through the StreamingRecognize API, But it is never working, I have running container as well as riva-servicemaker,  
I can run example notebooks perfectly fine.

Can you tell your way of doing this, How you did transcription using chunks, as I am trying to do it with flask socketio audio buffer.

Thank you.

Hello, you can use the [nvidia-riva/samples](https://github.com/nvidia-riva/sample-apps/blob/main/virtual-assistant-rasa/rasa-riva-weatherbot-webapp/riva/asr/asr.py) repository where there are examples of the use of the API in python or through the [Riva Websocket Bridge](https://github.com/nvidia-riva/websocket-bridge/blob/main/riva_client/asr.js) repository for JavaScript
