We have experienced several instances where making changes to the text-to-speech content in our IVR menus does not actually apply. The changes are saved but they do not apply and we have to copy/paste the content back in a couple of times to finally get the change to commit.
We do not raise support requests for this issue anymore because the engineers just tell us to stop using text-to-speech, but what they do not understand is that we a large customer, text-to-speech is the best option for us because we have over 400 IVR menus and using audio recordings and dealing with immediate changes from the business to these just does not scale.
Please can you improve the reliability of the IVR text to speech by:
a.) including a preview button so we can actually check the change made is working
b.) return an error in the UI of the content change hasn't actually applied
