Hello Ayoosh,
Welcome to NeuroTalk Support Groups.

A site that I found very valuable when dealing with post concussion syndrome was the Brainline site. I've posted a link below.

Traumatic Brain Injury: Cognitive and Communication Disorders | BrainLine
What are the cognitive and communication problems that result from traumatic brain injury?

Communication Effects After Brain Injury | BrainLine
Dysarthria

Of course, this may not be the actual condition you are dealing with, but I thought I'd post the information about Dysarthria in case it helps.

Dysarthria - National Aphasia Association
What is Dysarthria?

The subject of "Speech" is discussed. I hope it's not too difficult for you to read it all.

Wishing you a speedy recovery,
Lara
