Parleremo uses Teamspeak 3 as its voice chat software.
If you need further help installing Teamspeak, be sure to watch the Windows client installation tutorial video. Tutorial video here.
Once you have connected for the first time, you may need to set up your microphone. Click on "Settings" at the top and select "Setup Wizard". This will guide you through the steps to choosing you nickname and setting up and testing your microphone.
It is advised to use "Push-to-Talk" instead of "Voice Activation". Push-to-talk will allow you far better control over your microphone, preventing your microphone to start recording on background noises, as well as not losing the start and ending of what you are saying.
Also on the "Settings" menu is the "Options" section. Here you can change the setup you did with the Wizard, as well as how the Teamspeak 3 client looks and acts on your computer and the language it is displayed in.
You can get language packs, skins and plugins from the Teamspeak 3 forum.
