Voice message

Hey Vietuser,

We'd be happy to help out. Sounds like you're having an issue sending audio messages on your iPhone. To clarify, what exactly happens when you attempt to record audio messages? Is your voice not picked up? If not, test things out in the Voice Memo app to make sure your microphone is working as it should.

For more info, also check out these steps:

Send an audio message

1. In a conversation, touch and hold  to record an audio message.

2. Tap  to listen to your message before you send it.

3. Tap  to send the message or  to cancel.

Note: To save space, iPhone automatically deletes audio messages two minutes after you listen to them, unless you tap Keep. To always keep audio messages, go to Settings  > Messages > Expire (below Audio Messages), then tap Never.

This is outlined further here: Send and receive photos, videos, and audio messages on iPhone - Apple Support

We hope this helps out.

Take care!
