无法设置语音转文本 GCP api

Question

I've been struggling to transcribe audio to text in Python. Here's what I've done so far:

1. Got a GCP billing account with a 90-day free trial
2. Enabled the Google Cloud speech-to-text API
3. Downloaded a JSON file and set it as an environment variable (always have to call os.environ["GOOGLE_APPLICATION_CREDENTIALS"]='C:\\Python\\Python37\\Lib\\site-packages\\google\\Borster.json' in Jupyter, otherwise when I do it with set in the cmd, the variable disappears when I reopen cmd)
4. I then noticed that I " cannot import name 'enums' from 'google.cloud.speech_v1p1beta1' ". So, the only thing I could do as a bypass was to replace the speech_v1p1beta1 folder with another one I found on the web that did have the enums.py file.
5. Then, I made a bucket called 'callsaudiofiles21' in Google Storage, but still couldn't access it, because it was giving me the 403 GET https://storage.googleapis.com/storage/v1/b?project=i-enterprise-294210&projection=noAcl&prettyPrint=false : borster-659@i-enterprise-294210.iam.gserviceaccount.com does not have storage.buckets.list access to the Google Cloud project.
6. I then did some research and it turns out I can't list the buckets because I haven't assigned the proper role to my account. So I did, ...but still getting the same error.

I haven't been programming for too long so I'm very confused with this API and this whole Google Cloud platform in general. If there's anything else helpful I could share, please tell me. I've been struggling for 3 days but nothing going.

Answer 1

The service account that you create does not have permission to your bucket. The error message states that the the list permission is missing.

The solution is to use the Google Cloud Console (or the CLI) and add the appropriate role to the service account.

Granting, changing, and revoking access to resources

Select one of the Cloud Storage roles listed on this page:

IAM roles for Cloud Storage

The service account will need roles/storage.objectViewer
