KeenLore is my emotive audiobook creator, which I've been working on for the past several months to help me narrate my sci-fi novel. Here's a slightly outdated demo video:

I've since added character ages (child to supercentenarian voices, consistent relative to their base adult voice), crowd chants (2 to 100 people works flawlessly), case sensitivity for character aliases (to help detect quotation attributions), custom phonetics, and English speaking characters can have a variety of accents applied. Will soon have Chatterbox driving the novel's narration. Screenshot:

It's self-hosted, fully local, based on software having permissive licenses and open weights. Runs on a lowly 8GB NVIDIA T1000 (and 96 GB of RAM).
