Error: KeyError language after installing Amazon Polly SAPI

[rrhpablo]

Hi there!
I'm trying to use Amazon Polly voices on Calibre, so I installed the Amazon Polly SAPI software that AWS provides. But after it, I get the following error after trying to choose a voice on Calibre's Viewer:

calibre, version 6.10.0
ERROR: Excepción no considerada: <b>KeyError</b>:'language'

Amazon Polly voices are listed in the Narrator windows 11 app and in Polly Player. Is there something I can do to fix it?

It's cloud based thus all is sent to Amazon and speech returned. Severe issues of privacy and needing always on Broadband. You also need an AWS account.

Install a local TTS for your OS for Calibre to use.

Even Spying Google allows a standalone speech engine on Android which works very well in the Pocketbook app to read epubs.
