Google-cloud-python: Speech: 403 Request had insufficient authentication scopes.

[chemelnucfin]

See #3212 for more information

Getting the same error and also it gave me 403 request error.
google.api_core.exceptions.PermissionDenied: 403 Request had insufficient authentication scopes.

Note: Google SPeech API is enabled and I am using Python 3.6

Here is the code, thank you for your help.

You can't use the drive scope to access Cloud Speech, you need to use to google-cloud-platform scope, or just leave scope unspecified and the library will handle it.

@sohamsil I'm not sure if you saw this, but this was the answer to your question. Please feel free to ask if you have any more questions.

@jonparrott @chemelnucfin Thanks a lot for the help. Removing the scope helped and the code executes fine on my machine.

However, when I tried to run the same on Cloudshell it gave an invalid_scope error. I believe it requires the google-cloud-platform scope, correct me if I am wrong.
I tried the scope as https://www.googleapis.com/auth/cloud-platform but it's showing invalid_scope.

Note: After running pip install -U google-cloud-speech in cloud shell, it gave me the below exception.

@sohamsil you should use a virtualenv. See https://cloud.google.com/python/setup#installing_and_using_virtualenv

[sohamsil]

@jonparrott It worked in the cloud shell as well. You're right! I had missed out on creating a virtualenv while following the tutorials before this. Thank you :)

replace this line:

static string[] Scopes = { SheetsService.Scope.Spreadsheets.ReadOnly };

with this:

static string[] Scopes = { SheetsService.Scope.Spreadsheets };

and if you did not pass, delete (token.json) folder and try again
