*[https://ectwiki.online/index.php?title=Cognitive_Load_Theory Cognitive Load Theory]: a cognitive architecture of a human being is divided into three parts: a limited working memory, a limitless long-term memory, and schemas that work to organize in long-term memory (Sweller, 2011)

According to cognitive load researchers (Paas & Sweller, 2014), synthetic voices increase extraneous cognitive load and reduce usable cognitive capacity to integrate new information with existing knowledge. An unappealing voice may cause learners more time to generate the information which is more likely to increase the working memory that is distributed into the cognitive thinking process that raises the cognitive load. 

According to cognitive load theory assumptions, the human brain receives instruction in two different channels, verbal and visual, before information processing begins, and the capacity is relatively limited. As a result, synthetic machine-generated voice types may increase the extraneous cognitive load of those exposed to multimedia instruction or engaged in multimedia material because it appeals to the uninterested and distracting in the absence of sufficient social cues (Wouters et al., 2008).
