Yep, but text can also deliver crucial pieces of information within a small frame of time. When you see a text you can single out a few words and get a general drift of what is going on. Audio has to be rolled from start to finish to reach the same goal. That is why the dialogue text that you choose is also very important, it needs to give you the full story even for people that skip the voice line.
Generally I think voice is overrated, even by players that do not read, simply because those players also lack the patience to listen to 30s of voice, that they could have read in 5s. That is why there are also subtitles in most games. Even in those games you read more than you actually listen. But it is correct that large boxes of text seem intimidating to players, hence some marketing dudes told game devs that going full voice is the way to go.
