How to Use TinyTalk for Voice Chat on a Local Network or the Internet

TinyTalk is a legacy direct-IP voice chat tool for two Windows PCs. Its documented workflow is: both users launch it, the receiving PC listens, and the caller enters that PC’s IP address and selects Connect. A local network is the easiest setup; internet calls can be blocked by routers and firewalls.

Compatibility information for this release ends at Windows 7, so Windows 10 and 11 support is unconfirmed. I could not verify a current official download or support page. Avoid third-party mirrors and never bypass a Windows warning for an unverified copy. TinyTalk’s current encryption and access controls are also undocumented, so don’t use it for confidential calls.

Before you start

Both participants need a Windows PC, a working microphone and speakers or headset, and a network path between them. The old description lists installer and portable-executable versions, but no current requirements. If you cannot verify the program’s source, choose a maintained voice-chat application instead.

In Windows 11, open Settings > System > Sound, select the microphone under Input, and test it. Under Settings > Privacy & security > Microphone, enable desktop-app microphone access if needed; Windows 10 uses a different path. See Microsoft’s microphone troubleshooting guide.

Connect two PCs on the same local network

1. Put both computers on the same trusted network. They can use Wi-Fi or Ethernet, but a guest Wi-Fi network may isolate connected devices and prevent them from reaching each other.
2. Start TinyTalk on both PCs. The legacy description says it begins listening when launched. Keep the program open on the computer that will receive the call.
3. Find the receiving computer’s IPv4 address. In Windows 11, open Settings > Network & internet, select the active Wi-Fi network or Ethernet connection, then look for IPv4 address. The exact page can vary by Windows version; Microsoft’s network settings guide shows where to find it.
4. Enter that address on the calling PC and select Connect. Use the current address shown on the other computer. The sample address in the illustration is only an example, not a value to copy. If Windows asks about firewall access, allow the program only if you have verified it and only on a trusted private network.
5. Confirm two-way audio. Speak into each microphone and check that the other person can hear you. Keep the call limited to the people and network you intended.

A typical local IPv4 address may begin with 10, 172.16 through 172.31, or 192.168. Those ranges are reserved for private networks and are not directly reachable across the public internet, as specified in RFC 1918.

Can TinyTalk call over the internet?

Possibly, but an IP address alone may not work. A computer behind a router normally uses a private address, while the router handles outside traffic. A direct incoming call needs a route through the router and Windows firewall. TinyTalk’s documented requirements don’t specify its port or whether it uses TCP or UDP, so a reliable port-forwarding recipe cannot be given.

Don’t disable the firewall or open a guessed port. Microsoft says allowing a trusted app is generally safer than opening a port, though both carry risk. Only configure access if you administer the network and have verified, version-specific TinyTalk instructions. Otherwise, choose a maintained voice service or a VPN that supports device-to-device reachability; TinyTalk’s compatibility with a VPN is unconfirmed.

Troubleshooting a failed call

• Connect does nothing: Recheck the receiving PC’s IPv4 address, confirm TinyTalk is open on both computers, and make sure they share a non-guest LAN. Guest-network isolation can block them.
• No one can hear you: Check the headset mute switch, select the right input and output devices, test the microphone outside TinyTalk, and confirm desktop-app microphone permission.
• Windows blocks the program: Don’t disable the firewall. Allow only a trusted app on a network you trust, then remove the exception when it’s no longer needed. See Microsoft’s firewall guidance.
• LAN works but internet calling fails: Router, NAT, firewall, or version limits may be responsible. Don’t guess at router settings.

Bottom line: TinyTalk’s documented workflow is simple for two PCs on a reachable local network: launch it on both, enter the receiving computer’s address, and connect. Its age, unverified current download and compatibility status, and unknown internet-call requirements make it a poor choice for exposed or sensitive use.
