What happens to AI VO at the end of our free trial?

Hi, we have recently been trialing the new AI assistant features in Storyloine 360, but I was wondering what will happen to the TTS features after the free trial expires?

Will SL revert to the original VO options for TTS at that point?

Whilst I like the new VO options, I feel that the fact that the trial AI VO features have essentially 'replaced' the old voices in my SL app, is a little sneaky. Its hard to know what is part of a free trial, and what is part of separate ongoing SL updates. 

I dont want to work with voices features that might get removed if my company decides not to continue with the AI assistant features.
