Phonetic Keyboard

With the UZT keyboard the other keyboard that is used common is the phonetic
keyboard. Phonetic keyboards works with the sound of the words. e.g. 'a' button of
the English keyboard contain an Urdu word which is similar to the sound of 'a' and
same is the case for other characters. This was not mostly used in the past but
currently it is gaining pace and is considered a better and easy to use layout.
CRULP (Center for research for Urdu language processing) has been working on phonetic keyboard designs for URDU and other local languages of Pakistan. CRULP Urdu Phonetic Keyboard Layout v1.1 for Windows is
very famous and considered as a standard now for typing Urdu on Microsoft platform.
This version is widely accepted by local language community and has been finalized
after valuable feedback from users.
