a comparison of the voice lists for the S950 and S970 this afternoon, and here are the details. My apologies for any errors here; the compilation process was a little error-prone since I was extracting text from the Data List PDF's using pdftotext. Most of the list data below were automatically printed out by a script I wrote.

One of the changes was that a lot of voices are spelled differently now, mostly due to the voice names not being as abbreviated. For example, "SynStrings" becomes "SynthStrings". Perhaps this was partly motivated by the larger screen (more characters)? I did not list here any voices that had the same program numbers and voice type but which merely had a different name.

Of course I could not determine what changes have been made to the actual voice waveforms.

These lists include all voices, including those in the Legacy and GM/XG/GM2 categories.

The inclusion of the new sound effects voices is welcome. That was one of the disappointments on the PSR-S950 -- that some (but not all) of the sound effects voices had a similar poor quality compared to those on my 19-year-old PSR-520.

Organ Flutes Changes:
With the PSR-S970, Yamaha changed the program numbers for the OrganFlutes presets, so that the presets all have unique MSB/LSB/PC values. On the PSR-S950, the Organ Flutes presets all shared the same MSB/LSB/PC. This theoretically should be a welcome enhancement for folks using MIDI. Here are the new OrganFlutes presets, 10 or 11 total:
BalladEuro
BrightEuro
ClassicJazz (not sure if this is really new -- I think it is a placeholder to support MIDI data using the old MSB/LSB/PC values)
EuroAccomp1
EuroAccomp2
EuroAccomp3
EuroPerc
EuroPops
EuroReeds
EuroWarmth
FullEuro

Voices that changed type, total 44 (these are all switches to stereo samples. Note that some of these, particularly most of the drum kits, were already sampled in stereo on the S950, so Yamaha has just changed the teminology on them):
