I'd bet if you read the Dragon book (yes, I'm dating myself) you'd have something working in less than three months. More importantly, you would understand every bit of it.
Probably. I know what book you mean and never tried to read it. As I noted elsewhere I could probably brute force something in a week without reading the book. However the ai tried to be better than just a basic translator and that takes more time and exberience than I have.
