Getting error code 0x38 (SPXERR_AUDIO_SYS_LIBRARY_NOT_FOUND) when deployed to cloud.

Question

I am working on an interactive real time communication that uses both speech synthesizer and recognizer. In development it is working fine but when I deployed through azure web app in a Linux server it was giving the error. I don't want to process any audio here neither "output.wav". Is there any way I can configure the speech service SDK to use the user microphone on the browser to take audio input for real time recognition.

Thanks for reaching out to us, I have seen the same issue when there is a minor package missing, please check on the pre-requisites repo and make sure you have dependencies installed.

https://github.com/Azure-Samples/cognitive-services-speech-sdk/blob/master/quickstart/python/text-to-speech/quickstart.ipynb

I also saw another customer have the same issue caused by lacking of libssl-dev libasound2.

Please have a try and I hope it helps.
