Detailed Answer:

Hi,

speech is a very complex process and involves a lot part of brain, then the muscles, and the apparatus of articulation of the speech, problem can occur any where.
the details you provided are too little to completely understand as where can be the problem, (to know the cause)
however what I would say that if its of sudden onset, or recent onset, I would say you must see a neurologist to fine out the cause, (as it would be then mostly in the brain)
but if its by birth, then probably it nor very serious.
(I just wanted to know if you are already aware of what is the cause ?? )

whatever regarding to help it, its always a bit challenging , and would be focusing on the cause , but the role of the speech therapist is wonderful. speech therapist, though a prolong process, but is of tremendous help in whatever is the cause , so I would advise to see a speech therapist.

Hope I have answered your query, please don't hesitate to ask for any help you need in this regard, or if you have any further query.

Kind regards,
