Voice error: Error processing en-GB speech: 401

[tawny mirage]

I'm using Nabu Casa's speech-to-text service but getting this in the logs when activating my Voice PE (and the light just turns red after a second).

Anyone know what this might be? 401 suggests unauthorized but the text-to-speech service from Nabu Casa works fine for me.

I've restarted HA but to no effect.

Logging out under the cloud section and logging back in has fixed it, how odd!
