ben degil kemal konusmak, i dont speak to kemal.

degil soylemek ben. i dont tell.


is my translation on the right lines?

I think you are right but it's not easy to tell as the turkish is broken..

degil mainly negates adjectives not the verbs...
Ben güzelim Ben güzel değilim
to negate verbs we use "-me" (or -ma according to the other sylabbles)

Sevdim, sevmedim
Seviyorum sevmiyorum
