This is a very long battle trying to solve an issue with an automation I created in the Shortcuts app. I have been facing this issue on my old phone SE2 and now it's the same on my 12. I am running IOS 16.6 with the latest security patches/ updates.
Additional challenges faced are unable to delete downloaded Siri voices Settings/ accessibility/ spoken content/ voices/ English. An edit button appears which when clicked, allows you to delete the downloaded voices, but suprise, you can delete the voices even without clicking the edit button. Just swipe up/ down to get the delete option. Post performing this, the Siri voices appear to have been deleted as their state changes to download Siri voice. However, when you restart your phone, those voices that you just deleted are back!
This issue has also been reported to apple support multiple times with no solution yet. I have tried restoring, resetting all settings, deleting all apps., redownloading the Shortcuts app., Deleting the Siri Voices and redownloading them but nothing is helping!
I have included Screen and Video recording for this issue for the benefit of the reader I am also explaining the problem/ challenge here in text.
NOTE: I am also a VoiceOver user and have a sight impairment
Created a personal automation on the Shortcuts app. When any of 2 alarms is topped, get weather, text and speak text. While creating the automation and running it to test, the automation works flawless and the Siri voice used to speak text sounds just like it should. This is covered in the first video link.
The challenge: When the automation is triggered, i.e. when the alarm is stopped and the text is to be spoken; the Siri voice is all choppy and inconsistent. This is demonstrated in the second video.
P.S. It happens with all Siri Voices irrespective of Language selected in the automation i.e. Australia, India, United Kingdom, United States etc.
NOTE: It's the Siri voices I downloaded from: Settings/ accessibility/ Spoken content. Other voices downloaded work fine but they aren't as good and natural as Siri voices.
