Thank you for your question.
In its simplest terms Speech refers to the production of sounds/words whereas language refers to shared rules about how we communicate meaning. Speech is the ‘how’ we make the sounds, and language is ‘what’ we say.
An example of a speech difficulty might be saying ‘dat’ for the word ‘cat’
An example of a language difficulty might be the inability to understand the meaning of words or the inability to form a complete sentence.
I hope this helps, if you’d like to know more or feel you may need to book an assessment then you can do this on the website.
