InfiniteStreamRecognize - io.grpc.StatusRuntimeException: CANCELLED: Failed to read message when EnableVoiceActivityEvents is true

[stefalbi]

In which file did you encounter the issue?

https://github.com/GoogleCloudPlatform/java-docs-samples/blob/main/speech/src/main/java/com/example/speech/InfiniteStreamRecognize.java

Did you change the file? If so, how?

Added enable voice activity event option and set audio channel count to 1

RecognitionConfig recognitionConfig =
RecognitionConfig.newBuilder()
.setEncoding(RecognitionConfig.AudioEncoding.LINEAR16)
.setLanguageCode(languageCode)
.setSampleRateHertz(16000)
.setAudioChannelCount(1)
.build();

StreamingRecognitionConfig streamingRecognitionConfig =
StreamingRecognitionConfig.newBuilder()
.setConfig(recognitionConfig)
.setInterimResults(true)
.setEnableVoiceActivityEvents(true)
.setVoiceActivityTimeout(VoiceActivityTimeout.newBuilder()
.setSpeechStartTimeout(Duration.newBuilder().setSeconds(15L))
)
.build();

Describe the issue

After I receive the event SPEECH_ACTIVITY_BEGIN I get the CancelledException: Failed to read message.

@Shabirmean please, triage this issue. If the problem is with the sample, please submit a fix or comment with the problem description and/or fix suggestion

[minherz]

@stefalbi it will help us to triage the problem if you are able to answer to a few questions below:

1. Can you please confirm that the original example (without your changes) works as expected?
2. I assume that you added the links to this code block. Can you run your code without setting VoiceActivityTimeout and report whether you get this exception?
3. I assume that the CancelledException is catched by the catch exception block at the end of the sample. Can you please post the full content of the exception printed by the catch block?

Thank you

[stefalbi]

1. yes, it works
2. without setting VoiceActivityTimeout it does not works
3. I made a new test and printed the error wirh the stack trace on this method, the exception causing the CANCELLED message was an IndexOutOfBoundsException , the sample does not handle StreamingRecognizeResponse on the ResponseObserver onResponse method with empty ResultList, causing IndexOutOfBoundsException here

@minherz Shabir does not work on samples anymore, can you reroute? Thanks!
