+## What can u do better
+
+* Fit better model (with another hyperparams or bigger dictionary)
+
+* Add many new words into [dictionary](https://github.com/PasaOpasen/PersianG2P/blob/master/PersianG2p/data/tihudict.dict). If u want, I will write Python/C# script for this task or even create Telegram bot
