Is it possible to record voice from pc microphone, or phone mic , save it and play it back. Or at least play it back without saving it.
I do not see this anywhere under help or tutorials. I do see voice synthesis and recognition, but not recording and playback
I would suspect you would have to direct them to a webpage that records and saves the recording and then you could load that from the URL.
BUT what you are suggesting falls under some legal issues in the US concerning phone tapping laws so just be aware that recording anything without consent using a phone or PC is against US laws.
