I'm trying to use Google Cloud Speech api to recognize speech, following the example code at
https://github.com/GoogleCloudPlatform/java-docs-samples/tree/master/speech/grpc
I've followed the instructions and created credential(Service account Key) as mentioned here and also created the billing account.
when I'm executing mvn clean install command, while it starts running the test cases; I get following error:
> Running com.examples.cloud.speech.RecognitionAudioFactoryTest
