VoiceOver Speech Output Spontaneously Stops

VoiceOver speech output spontaneously stops and requires a wait of about 30 seconds to resume. The issue is not specific to certain apps or actions and occurs without any clear pattern. Restarting VoiceOver can help, but it may take a couple of cycling of VoiceOver for this to work. The issue only affects the VoiceOver voice and not other VoiceOver audible feedback. The issue appears to affect many VoiceOver voices, including Alex, Eloquence, Ava, and Siri.

This issue has been reported by multiple users on the AppleVis forum: https://www.applevis.com/forum/ios-ipados/voiceover-crashing-ios-164

Based on our experience, it seems that the frequency of the issue is not consistent and appears to be influenced by the VoiceOver voice being used and the intensity of usage. Using the Alex voice, we have observed that this issue typically arises 2-3 times a day. However, based on the comments shared in the forum topic mentioned above, it appears that some users encounter this problem more frequently than others. Some users have suggested that this issue is most prevalent when using an Eloquence voice.
