Tested with IPhone 13, iOS 15.2.
Hey everyone. I and others have posted on the Applevis forums previously, wondering how this may be done. It seams there is a way.
I used to think that it was a cirtain Blue Tooth codec that would allow Voiceover to stay on the iOS devices speaker, and other audio through a Bluetooth audio device, but it seams that some devices may be showing themselves to the iOS device, as a speaker, and some not. When devices are recognised as speakers, Voiceover stays routed to the iOS devices speaker.
Here is how to show your audio device to iOS as a speaker:
Audio demo at:
Text instructions below:
On the iOS device, open settings,
and scrol down to the Blue Tooth device you are wanting to customise.
Flick down and double tap on more info.
Once the More Info dialogue appears, find the
device type, button and Double tap.
You will be presented with several options. Swipe until you find, Speaker, and doubletap.
Voiceovers speach should then be routed to your iOS devices internal speaker.
I will note here before others do, that yes, there are bugs currently with Voiceover routed through the iOS device when connected to a Blue tooth device. Voiceovers volume randomly may spike to full volume, when, there is a pause in music or another audio, or, when increasing the volume of other audio. I do though, still believe this information is valuable, as some may choose a Blue tooth speaker, bassed upon others testing, that Voiceover may be routed to the iOS device.
