Hi, is this project still active?
Some time (a few years) ago I contacted the developer as I was intending to add statistics and 'phonetics' to improve the n-gram accuracy and allow for other types of spelling mistakes not currently handled by Hunspell. There seems to have been some work done on the project since then, though now it seems to have stagnated.
Anyhow, I'll post on the mailing list.
Nope, it's dead.
