My son had to have speech therapy when he was young, and I have to say the speech therapists were amazing.
They are very skillful and it is only when you watch them work you realise how complex speech and language is, and when it goes "wrong" what has to be done to teach it bit by bit.
It is not an easy job for an untrained person to "teach" someone to speak properly as it is all to do with the make up of words, the "sounds" of parts of words, the shape and movement of the mouth and tongue etc.
If you are that concerned go to your GP and try to get the doctor to get her to a speech therapist.
