Hi Dogguideguy24,
There's no reason or setting that would cause the dictation button on the keyboard to play music. Is this being triggered by some type of 3rd party hardware?
In the meantime, here is an article on using dictation on your iPhone: Dictate text on iPhone - Apple Support
"Dictate text
- Tap to place the insertion point where you want to insert text.
- Tap
on the onscreen keyboard or in any text field where it appears (as in Messages, for example). Then speak. - If you don’t see
, make sure Dictation is turned on. Go to Settings
> General > Keyboard, then turn on Enable Dictation. - As you speak to insert text, iPhone automatically inserts punctuation for you.
- Note: You can turn off automatic punctuation by going to Settings
> General > Keyboard, then turning off Auto-Punctuation. - As you dictate text, you can insert emoji by saying their names (for example, “mind blown emoji” or “happy emoji”).
- When you finish, tap
.
