[COGA-Voice]:About Challenges for People with Disabilities that Impact Cognitive Accessibility

Issue 1:
General Concerns (2.1 states, "Voice systems and conversational interfaces
depend on the users’ knowledge and abilities".
Comment: Is this not true of all UI? Not special to voice / conversational
UI IMO.
Example: A comparison of mobile tablet devices may state technical features
like, Computer Memory Type, Flash Memory Size. If a user does not
understand these terms enough it is due to a knowledge gap and can happen
to a non-PWD too.
Other examples: option strategies for stocks or a web page discussing an
involved topic in physics or computer programming or corporate taxation.
 Now if the user is well versed in the topic being reviewed but due to a
acquired cognitive impairment is unable to recollect what some terms mean
or they seem unfamiliar, or has problems in analyzing and choosing a course
of action, it is not a problem of "knowledge". It is a memory issue or in
some cases, reasoning.
Issue 2:
Both 2.4 and 2.7 are identical:
2.4 Reasoning: Making the Correct Selection
2.7 Attention: Making Correct Selections

Comment: Is 2.7 supposed to refer to attention span and how distractions
might make one lose task focus?
