Diagnose and treatment

Are there any assignment tools to diagnose the speech?
To diagnose the speech it is important to make an acoustic analysis with some measuring instruments which have to be used. These instruments are the rhinoscopy, nasendoscopy, otoscopy and audiometry. With these, all the structures responsible for the speech can be observed and a diagnosis can be made.

After this, an acoustic study will give more specific information about which sounds are more difficult for the child and which compensatory sound he produces. This acoustic study will consist in recording the productions of the infants and it has to include words or sentences with all the different sounds the language has, and in all the possible positions.
