Microphone and Tiny Speaker
My requirement needs microphone and speaker on board, is it possible at present?
Metawear is a Bluetooth Low Energy board. Microphone and speaker is an application for normal Bluetooth.
Bluetooth can't handle wireless data transfer speeds required for audio. So although you can hook up a microphone and speaker on the board there is nothing you can do with it at all; at least it wouldn't really be functional. If you write your own firmware drivers there's some stuff you can do but it is not a light undertaking.
