There are plenty of people that I see, as a speech-language pathologist that have a combination of issues as you describe. They can have any combination of articulation, fluency, voice quality, receptive language and/or expressive language difficulties. If you have no receptive language difficulties (that is, comprehension or understanding) then you have a specific language impairment involving expressive language....along with some articulation differences....and a dysfluency. This is not a diagnosis but a description of what you described.
