What does the error message "Code 403: The request is missing a valid API key" mean in relation to using Google Cloud's speech-to-text API with a service account key in Python?

The error message "Code 403: The request is missing a valid API key" means that the API request made to Google Cloud's speech-to-text API did not include a valid API key. This API key is needed to authenticate the request and verify that the request is authorized to access the resources. In the context of using a service account key in Python, it may mean that the key used in the code is either invalid or has not been properly configured to have access to the speech-to-text API. It is necessary to ensure that the service account key is valid and that it has the necessary permissions and roles to access the speech-to-text API.
