#119 Bug in Amharic

[Marco Oros]

Hello.
I notice a misstake in Amharic.
Letters, when You write in Amharic keybords as kha, khe, khi or kho are pronounced as [[h'a h'e h'i h'o]]
This letters must be pronounced as

[[x'a x'e x'o]] (ValueError('No closing quotation'))

ETC.
Please, could You fix that bug?
Thank You.
