TeamSpeak 3 offers a free way to communicate by voice whether you're playing games, at school or working.

TeamSpeak been around since 2001 and has matured well with great voice quality and low memory and processor usage. While many apps have simply updated over the years, TeamSpeak 3 is a complete rewrite of its protocol and core technology.

The latest versions are easy to use whether you're new to TeamSpeak or if you've been using it for years.

TeamSpeak uses private servers to communicate. If you want, you can host a server or rent a server from hundreds of providers by the month, annually or yearly. Then you give the information to whoever needs it, and they connect via the desktop application or the Android or iOS apps.

TeamSpeak promises the best voice quality using the Opus audio codec combined with automatic microphone volume adjustment, background noise reduction, and echo cancellation. You can easily chat with just a few people and scale up to hundreds of people.

For security, you have many options as to who can join your server. It's up to you who talks, who can join, remove users, and more. AES based encryption can be enabled for additional security. Because we all know people like to use simple usernames and passwords, TeamSpeak uses public-private key authentication to protect against it.

Finally, TeamSpeak lets you customize it how you want it with the included themes, sound packs, and designs.
