I was watching "Collision Course" and think I heard a familiar voice. The unseen woman who pages, "Dr. Braden, two four two one. Dr. Braden, two four two one" after Mac's friend is admitted to the hospital sounds an awful lot like the voice of Sandy, the computer program that tried to kill MacGyver and Dr. Ludlum in "The Human Factor".

I watch the end credits and there is no mention of a voice-over actor.

Any thoughts?

If you listen to the dream doctor in Brainwashed (the one they take Jack to see at the Phoenix Foundation) she sounds like the same voice as well.

That actor (Linda Darlow) is also in a couple of other episodes, but in the Brainwashed episode in particular, she sounds identical to Sandy, so I can't help but wonder if she did the occasional uncredited voice job for the show.

Sure sounds like the same voice. It could definitely be some uncredited work she did.

Other fans over the years have also noticed and asked the same question.

If I remember correctly, what sounds to be the same voice is also heard elsewhere in the series as well, but you're right they do all sound the same.

There doesn't seem to be any decent information about Linda anywhere save for this little snippet from Audition Craft website which says

Which hints that it's certainly a possibility that she has done voice work.

Wow you're right, there isn't much info. about her anywhere at all. I'm a little surprised that there isn't
