Issue :: Microsoft Cognitive Services :: client-sdk :: Azure

Question

I am trying to use Azure cognitive services and trying to convert "Text To Speech". I am able to convert the Text to Speech successfully on my local machine. The issue only happens when I deploy my application to Azure cloud using "App Services". I am getting the following error/exception when my code tries to create SpeechConfig e.g; SpeechConfig config = SpeechConfig(mySubscriptionKey,service-region)

Exception: UnsatisfiedLinkError

I am using the following tech stack on Azure cloud: Spring Boot 2.6.7 Linux (Tomcat embedded container) used by Spring Boot. client-jar-sdk 1.14.0 (com.microsoft.cognitiveservices.speech)

I am NOT using any Container or Container Service like Kubernetes in this example. It is a simple webapp deployed to Azure using App Services.

Note 1: Please note that I have also tried to use Microsoft cognitive services client-sdk (1.21.0), but I am getting the same exception. I went on google and found that other people were facing the same issue, but there was no satisfactory answer given.

https://docs.microsoft.com/en-us/answers/questions/660957/text-speech-when-speechconfig-init-got-error.html

Note 2: Please note that I am NOT using a free subscription and the resource group region is eastus.

Note 3: I have tried and deployed many code examples (for the Text to Speech) provided my Microsoft and other people on the internet but I am getting the same issue in the Azure Platform ONLY.

Answer 1

• Before creating your stream class, make sure you call SpeechConfig.fromSubscription(KEY, REGION) (or one of the other from*() functions) at least once.
• The reason for this is that the speech sdk only loads the native dll at the "entry" classes automatically, such as SpeechConfig or Recognizer classes.
• Refer these links for more information:
