Hi Chris,
I'm relatively new to 8x8 configuration, but I think I can offer some help. In the script that you set up for the post call survey you can use an option called Question.
When you edit that option you get the opportunity to add an audio file for the question prompt. You could use your own custom recording here. Interestingly there's no option to use the computer-generated voices in this section, which feels like a bit of an oversight if you wanted to create a quick survey but didn't have the recordings ready to go.
Hope that helps.
Nick
