This must be partly cultural. I'm currently in China, and a ton of people who use WeChat speak into their phones to send voice messages, rather than type. They hold the phone so that the phone's mic is close to their mouth. When they listen to voice messages, you can see them holding their phones up to their ears to hear their phone's speakerphone clearly. And yet there I am, mostly typing my WeChat text messages instead of sending voice messages. Though I sometimes hold my phone's speakerphone up to my ear to hear someone else's voice message.... edit: clarification on holding phone
