Chessmaster 2000 for the male and female voices of the chessmasters? Classic, especially back in those days.
Do any of the text adventures use speech to read out the text? I imagine they must. I remember enjoying the text adventure "Haunted Mansion" from the SPOC disk (released I think 1986, missing from HOL). It used speech to read the text that was being displayed. Although it did not have pictures like some of these, and perhaps the story may not be as intriguing.
