Yes, you will need a microphone to talk. It is the instrument through which your voice will pass. The microphone is an essential part of talking.
To do voice chat you have to enable video chat. You can also enable a phone call from your chat window. These are your two current options.
Go to 'Google Voice' with a gmail account and put in another gmail account that is in use to the person that you want to talk to. You can talk if you have a headset microphone combo tool.
You can scratch it, clap or snap into it, or talk into it.
If you need to see if your iPad microphone is working, an easy way to test it is to take a video of something with sound (yourself talking, the TV, the radio, etc.) When you play the video back, if you can hear it then you know that your microphone is working well.
to test if it works
Open Control Panel Open Sounds and Audio Click the "Voice" Tab At bottom right, click "Test hardware" button In next window click "Next" After the "Speaker Test" the Microphone Test window will open. Click the "Next" button If you receive an error, check that the microphone is plugged into the correct jack. If you have an extra sound card installed use the jack on it, not the original jack built in.
This isn't exactly the correct answer, but you can plug your headphones into where your microphone would be plugged in at (As long as it isn't headphones that plug into an USB port) and they would work as a microphone. (Download audacity if you want a good test of this.)
