The present maintainer does not wish to continue to maintain these and
we gather has asked for a new maintainer without any offers.
The forthcoming CRAN policy is to not allow packages to require (e.g.
via Depends/Imports) orphaned packages, so we need to ask you to move
these packages to Suggests and use them conditionally (see §1.1.3.1 of
'Writing R Extensions'). Please do so before Jan 31 to safely retain
your package on CRAN.
For ari, aws.polly needs to be used conditionally (it is not). Please
correct by the same deadline.

I think this should solve this
