Internal speaker/mic bad?

Just today, out of the blue, I went to send a text message and was using the voice to text and spoke my message but the phone said no voice heard. I tried this multiple times with the same result. I then tried to call somebody and they said they could not hear me, and I could not hear them. I then put the phone on speaker and both they could hear me and I could hear them...

any ideas? and yes i tried a battery pull
