since most context commands are instances of more generic ones, you can 
define another style to process the file to something suited for blind, say:

\setuphead[chapter][style=normal]

but that could be a lot of work. More simple is to use pdftotext which 
works ok for most cases,

\setuplayout[header=0pt,footer=0pt]
\setupcolumns[n=1]

is then probably enough

btw, there are ways to get auditive info in the pdf file, for instance let 
the voice engine speak and so
