Getting metadata/progress of a long-running recognition #819
Description
In which file did you encounter the issue?
java-docs-samples/speech/cloud-client/src/main/java/com/example/speech/Recognize.java
Did you change the file? If so, how?
I modified the while loop to attempt getting the progress of the operation in asyncRecognizeGcs(String gcsUri)
OperationFuture<LongRunningRecognizeResponse, LongRunningRecognizeMetadata,
Operation> response =
speech.longRunningRecognizeAsync(config, audio);
while (!response.isDone()) {
ApiFuture<LongRunningRecognizeMetadata> future = response.peekMetadata();
if (future != null) {
LongRunningRecognizeMetadata meta = future.get();
if (meta != null) {
int percent = meta.getProgressPercent();
System.out.println(String.format("Percent complete: %s%%", percent));
}
}
Thread.sleep(500);
}The while loop used to be:
while (!response.isDone()) {
System.out.println("Waiting for response...");
Thread.sleep(10000);
}Describe the issue
API version in Gradle: 'com.google.cloud:google-cloud-speech:0.21.1-alpha'
Using some test audio about 14 seconds long, getting the metadata of the response doesn't return anything until the response is complete. Using response.peekMetadata() leads to returning 0% until the response is done. Using response.getMetadata() of course makes the later future.get() blocking, but the only time it returns is at the end with 100%.
From the documentation on the metadata in REST it does show that progress can be returned, but Java uses gRPC.
Perhaps I'm using the code incorrectly, but otherwise would hope for some documentation or the feature to be available in the Java client library. Having progress output for very long audio (now up to 3 hours after the recent update) is almost necessary.

hi jbrew , are you able to solve this issue? i tried using 0.25.0-alpha version, but still not working, any work around?

@gguuss / @nnegrey PTAL

OK, I was able to reproduce what @jbrew138 is seeing:
According to the docs, this is actually the expected behavior, only the 100% progress indicator is guaranteed. That said, this looks like a feature that we should be implementing (intermediate updates to results in long running speech operations).

it would be very useful to have an indication of the progress.
i'm using REST to read progress . I realized that the progressPercent attribute is not present in the json if it has value 0 or if the file is small and therefore the progress goes immediately from 0 to 100 !!
I think it would be more correct that the progressPercent attribute was always present even if it has a value of 0.

@gguuss in json jumps from 0 to 100 is true for small file. try it with very large files. look at my previous comment
