I've continued working with using the IMS-Toucan to create a TTS for Cherokee. Much progress has been made and the system appears usable enough to go ahead and switch over to creating lesson audio. For those interested, I maintain a fork of the repo at Cherokee Language IMS-Toucan.

I've attached readings of The Wolf and the Crawdad, The Search Party, and The Turtle and the Rabbit from the book Cherokee Reference Grammar - Brad Montgomery-Anderson (2015) as well as readings of the Two Hunters story from the Cherokee English Dictionary.
