Hi,

A 503 is most like a network issue.

Could you give any details about your networking, e.g. any proxies that might cause problems? Maybe there is a firewall? The error indicates that some network connections might be blocked.

How do I verify that

You should check if there are any networking settings blocking connections. 503 means the library is unable to make a connection with the backend API.

One thing you can do is try to load the discovery doc at https://speech.googleapis.com/$discovery/rest?version=v1 (no authorization is required, but it is served at the same endpoint). If you can access that page you should be able to make requests to the library.

curl "https://speech.googleapis.com/\$discovery/rest?version=v1"

>>> import requests
>>> requests.get("https://speech.googleapis.com/$discovery/rest?version=v1")
<Response [200]>

In different ways, there are different results

1.run at terminal

2.run pycharm

[LivenBom]

run python then will get this result

Apologies, this one fell off of my radar.

From the second to last post, it looks like there is likely something blocking network connections (https://stackoverflow.com/questions/58168189/serviceunavailable-503-failed-to-connect-to-all-addresses-during-attempt-to-rec describes some possible solutions).

I'm going to close this issue since it has gone stale, but please do open a new issue if you are still experiencing issues.

请问解决这个问题了吗？

请问解决这个问题了吗？或者说有没有办法加proxies呀，感觉有地方加proxies问题就解决了

可以使用Colab作为转接。如果只是简单调用，用Colab可以连通
