Helix remote voice - how well does it work?

Hi everyone,

My mother is 91 years old and almost blind. She lives in a seniors residence in Montreal. We are currently thinking of switching her to Helix because of the ability to use the microphone on the remote to change channels, etc.

Can anyone tell me how well it works? I should add that if it shows text on the screen requiring confirmation or something, she won't be able to read it.

Thank you. I have some other questions but I'm going to post them separately.

Susan
