The playback speed (and pitch) of cassette tapes is notoriously inaccurate, +/- 2 %. Furthermore they are easily damaged. You would need to include an audible cue when to switch the slides.
It is far easier to scan the slides and place the digital images in a video timeline along with a sound track. I have done this many times, mostly to music I've personally recorded or was supplied to me by the performer. The timing us usually constant, but is easily adjusted to fit the music. You also have many choices of transition, including cross-fades and various wipe styles. I use Adobe Premiere Pro, but there are many alternatives.
I usually deliver the results in 1080p30 (or 60) HD in MP4 format. Many DVD players will display MP4 video from a data disc. I make DVD movie discs on request, which are wide-screen, standard definition (854x480).
Slides were a common way to share awesome pictures and tell a story. But they are mute... obviously. Unless when combined with a cassette tape that narrates the story through music and voice, signalling when to project the next breathtaking view of space.
For some time now I have been wanting to bring these embodiments of humble 60's to 80's entertainment into the more easily accessible digital domain. It's rather simple: Scan the slides in high resolution, restore them, digitize the cassette with a good quality cassette recorder, restore if needed. Synchronize the two inertly separated mediums in a video editing program and voila!
