I finally found the trial setting you mentioned. You have to look at quotas for project and there will be a blue button indicating "Upgrade Account".
I did the upgrade but no change still getting the error
Request payload size exceeds the limit: 10485760 bytes.
Using the Cloud SDK for Speech recognition and sending the request via the command line for a long running recognize command. No syntax errors other than a change to the example they gave was needed
Example, had to remove the single quotes around the file name and don't have spaces in your filename
gcloud ml speech recognize-long-running \
'gs://cloud-samples-tests/speech/brooklyn.flac' \
--language-code='en-US' --async
I seemed to be logged in properly, is it possible it is not recognizing my credentials properly and defaulting to trial type of request?
