iOS appears a new error that causes iPhone to crash only by voice

This error on iOS relates to the dictation feature (Dictation). Specifically, users who recently discovered their iPhone will immediately crash and restart if they say a few words using the "Read spelling" feature.

The strange thing is that this error is 'immune' if you input data using the keyboard or using Siri virtual assistant. Only when the user uses the voice for the Spell Reading feature will the iPhone restart.

All iOS 11 and iOS 12 versions (including the latest version of iOS 12.1.4 and iOS 12.2 Beta) have this error.

To activate this error, the iPhone needs to turn on the "Read dictation" feature (access Settings -> select General settings -> select Keyboard -> select Enable dictation).
