How can I loop my voice message?

Hello jbauer0.

Thank you for using Apple Support Communities. We want to make sure we're on the same page and understanding your issue/question correctly. It sounds like, you'd like to know if it's possible to loop a voice message. Is this an audio message that was sent to you via the Messages app or a Voice Mail message? If it's an audio message that you received, there isn't a built-in option that allows you to loop the audio message within the Messages app. The following resource does explain what you can do with an audio message:

We do recommend that you leave Apple feedback on features they can change or update here:

Thank you for using Apple Support Communities. Cheers.
