I find listening to voicemails on Facebook Messenger and WhatsApp very time consuming. In particular, the Facebook Messenger interface doesn't let me skip in the message if most of it is irrelevant to me.
People leaving a voice message tend to umm and aah, and the content of the message is generally less structured and coherent than text which can be edited for clarity.
How do I politely ask people not to send me voicemails, and to resend their message as text?
The messages I'm receiving now are from friends as I'm not currently working.
I generally explain that I'm trying to value my time more highly and that I find text messages clearer. (I'm still looking for a concise (yet polite) set of words to quickly and easily enter via my phone.)
How would I approach the situation in a work context or where the sender of the voice messages is my superior?
