I've been working with using the IMS-Toucan to create a TTS for Cherokee. My previous attempts with the Tacotron model kept resulting in problematic models that had a tendency to "ramble" on with "mumblings" in a not entirely predictable fashion. I maintain a fork of the repo at Cherokee Language IMS-Toucan.

The results I've obtained from the IMS-Toucan FastSpeech2 model are much more reliable.

I've attached a copy of three different TTS voices reading the Two Hunters story from the C.E.D., pp354-355. Cherokee Dictionary
