Why won't my Personal Voice read PDF text on iPhone?

Re: " I set up personal voice but it won’t read text to speech in pdf with my voice

it reads the last voice that was used if I change to another voice besides my voice it reads"

Seems personal voice is used to speak for you, while you type, instead of using your own voice.

ie: It can only be used with Live Speech... rather than serving as a screen-reader.

More info: Apple support's online article

Create a Personal Voice on your iPhone, iPad, or Mac - Apple Support

Eg: says:

"With Personal Voice, you can create a synthesised voice that sounds like your own to communicate with family and friends. Use your Personal Voice to type to speak in FaceTime and phone calls, assistive communication apps and in-person conversations."

and

"With Live Speech, you can type and have your words spoken out loud using your Personal Voice that sounds like you.Find out how to use your Personal Voice with Live Speech"

and also:

"Personal Voice can only be used with Live Speech and third-party apps that you allow, such as augmentative and alternative communication (AAC) apps. You can control app access to Personal Voice in Settings (or System Settings) > Accessibility > Personal Voice. Additionally, the third-party apps you grant access to can’t capture speech from Personal Voice."

Good to know. Thank you for replying. Cheers!
