The relationship between working memory and speech has been a topic of intense research interest and investigation for many years. Memory studies have found that the active processing of working memory is required for language comprehension and speech production. Though there are studies that discuss the capacity of working memory, the processing of verbal stimuli into verbal memory remains unclear. Therefore, it is essential to understand the functioning of the working memory and how it processes verbal information. As working memory is intricately linked with communication, any deficits in working memory could cause communication disorders. Also, the disruption in the storage and retrieval of verbal memory could cause a disturbance in the speech pattern. To this point, this review elaborates on the active processing of working memory and its role in communication. Further, by studying the deficits in working memory that could cause cognitive-communication disorders such as apraxia of speech, dementia, and dysarthria, this article highlights the importance of verbal memory in speech.
