A tool sounds out the words while a student reads them, and it is easy to suspect it simply reads for them. But if consumes attention, freeing that attention ought to help comprehension. What turned up among students with ?
A moderate average gain. Across studies of students with reading difficulties the average effect on comprehension was 0.35 . That does not mean the tool teaches reading or helps everyone equally; it may reduce the effort of decoding words and leave more attention for understanding the idea.
Reading aloud does not replace the text; it adds an auditory channel to the written information.
The main hypothesis is that the tool frees resources: less effort identifying the word and more effort connecting the ideas.
The average effect was positive, and study design explained some of the differences. That is a reason to be wary of a sweeping promise.
In educational use you also have to measure independence and comprehension over time, not only a score on a test taken right after listening.

Accessibility can change the route to a text without lowering the level of content a student can learn from.
How do we know?
A meta-analysis combined studies comparing comprehension with a read-aloud tool against comprehension without it, among students with reading difficulties.
What is still unknown
