Translate Non-English Voice Message to English?

Living in Southern California, I often get robo calls in various languages. I have my phone set to not answer numbers it doesn't recognize. A while back, I got a voice mail. One of my Mandarin speaking friends told me it was for "me" to contact whatever company because my visa was expiring. (I'm a fifth generation American, so don't need a visa.)

In any case, I've now received two more of these. I don't know if they're in Mandarin or Cantonese. I was hoping to play them on my phone to the translate app on my iPad, but it doesn't pick anything up.

Any idea how I can get these to work with the translator app?
