Is it possible to send old voicemails to email on Android phones?

My girlfriend has a lot of voicemails on her motorola g6 from a girl that was like a daughter to her. Her voicemail is completely full, and trying to find a way to transfer them to a computer. I’ve tried using Audacity to record them, but have had no luck. She’s now trying to figure out if there’s a way to send them to email. I know that there’s apps that forward new voicemails to email, but don’t know of any that can be used for old ones. I don’t believe she’s got visual voicemail on her phone. She uses a prepaid plan through Verizon.

The original voice mails should still be on the Verizon voicemail servers, unless she set them to auto delete after 30 days, or manually deleted them after listening to them. She should figure this out First, before messing with the saved audio files on the phone if they are important to her. 

From most carriers, you can access your voice mails from your online account, to listen to them or export/download them to your computer. If it were me, I'd check there first, and you may have to make a call to Verizon customer service and ask for voice mail tech support to find out the best way to export voice mails to the computer, then manipulate the files. Once happy with the outcome, then delete any voicemails saved to the phone.
