An efficient way to transfer WhatsApp voice messages into Anki?

I am working on a deck for an endangered language. Few of the remaining native speakers send me pronunciation of phrases and words on voice messages on whatsapp. And I have an Android on my phone, I also have WhatsApp desktop. What would be the most efficient way of transferring those voice messages into Anki entries?

PS. I am completely new in this forum, so apologies if a similar topic has been covered before. Help much appreciated!
