You should seek the help and advice of a licensed, certified speech-language pathologist. Even if you saw one in the hospital but discontinued services after a period, continued therapy can help. Depending on when you had your stroke, and the location/extent of the lesion, your speech may or may not improve. An SLP who specializes in aphasia can help determine the best way for you to communicate. Best wishes for a return to the things you enjoy most.
