No, the Acer Aspire 5332 does not have a built in microphone. You need to buy a microphone that plugs into the "mic in" jack which will be situated on the edge of the laptop with a microphone icon next to it.
Or you can buy a computer headset which is a pair of earphones and a microphone pod combined.
Thank you for taking time to help, Phil. Will buy a microphone as suggested by you. Thank you again.
