We built a similar app for asynch 1-1 & group voice chat (back in 2010 or so, it was called Voicee). Found exactly the same thing (even when we/founders were developing it and knew how to use it). It's so much easier to keep blabbing and that will put the burden on the listener(s) to spend time & focus on playing it. We didn't have audio transcription, so this may change the game a bit. So, if the sender can't (or doesn't want to) type at the moment, could reply to an otherwise text stream via voice. When we started, iMessage, WhatsApp didn't have asynch voice capability, but now they do - I guess having transcription always enabled would be a differentiator. But in general (a request that I ignored for too long), you'll have to have texting capability in your app too, otherwise people will gravitate towards whatever allows them to read & type without distracting others with playing audio...
