In speech input, introduce a 'warm up' screen for slow audio capture devices.
In some hardware/OS configurations it takes several hundred milliseconds to seconds for the audio driver
to get initialised and start giving audio to the application. We start by showing an empty bubble and if
audio was received within 500ms the usual volume meter becomes visible. If audio data was not received
within 500ms we start showing a light gray spinner animation to signal that things aren't ready yet to
start speaking.
