No. Only you can modify/update your speaking character and what it says, by logging into your SitePal account.
Once you make changes to a SitePal Scene in your account, these changes will be immediately reflected on your web pages everywhere that Scene is embedded.
Of course, if you want to enable users to select their avatars and enter text or audio for the avatar to speak, that's possible to do with our APIs. Depending on what you want to do, it may require the Enterprise API (which requires the Platinum plan).
If that's what you are looking for, it might be helpful to discuss/advise - please reach out to firstname.lastname@example.org.
