talk to text

Hello chelsee09,

Thanks for that info and for choosing the Apple Support Communities. If we understand correctly, you are unable to use dictation on your Apple Watch when listening to music with your AirPods. Based on your description, you may need to pause the music to use dictation:

"Dictate text: Tap , say what you want to say, then tap Done. You can speak punctuation, too—for example, “did it arrive question mark.”

Also, you can use your iPhone to enter text instead:

"Enter text with your iPhone: When you start composing a message and your paired iPhone is nearby, a notification appears on the iPhone, offering to let you enter text using the iOS keyboard. Tap the notification, then type the text using the iPhone keyboard."

And there is more options listed here: Send messages from Apple Watch - Apple Support

Cheers!
