How to translate a PC game’s dialogue

Found a great game with no dubbing in your language? With Langless and a virtual audio cable, the game’s sound goes into the translation and you hear the dialogue and story in your language, in real time, in your headphones. This guide shows the setup on Windows, how to keep the game’s music and effects, and the limits.

What you need

• A Windows computer, with Chrome or Edge.
• A virtual audio cable — VB-CABLE (how to install it).
• Headphones.

Step-by-step setup

1. Open the game. On Windows, in Settings › System › Sound › Volume mixer, send the output of the game only to the cable (CABLE Input). The rest of the computer keeps playing in your headphones.
2. In the app, set the game’s language as "Other language".
3. In Listen, pick Microphone, with the cable as the input (CABLE Output), and the Continuous style (the app remembers the last style used).
4. Leave Langless’s output on your headphones, not on the cable: otherwise the translation loops back into the input.
5. With the game playing sound, tap "🎧 Test capture": the meter should move. If it stays still, close the game and open it again — some games only use the new output after being reopened.
6. Check the target button: it should show "🌐 Translates to" your language. If it shows the game’s, tap it to switch.
7. Press ▶ and play.

Keep the game’s music and effects

With the game on the cable, you hear only the translation. To also hear the game’s soundtrack underneath, turn on "Keep the background track (music/effects)" before pressing ▶ and adjust the original volume. The original dialogue comes back too, quieter, under the translated voice.

Limits

• Dialogue and story: it works better in RPGs and story-driven games than in fast action, with lots of people talking at once.
• Delay: the translated voice arrives a few seconds after the line, in the AI’s voice.
• Long sessions: the translation has to be restarted every 3 h and stops by itself after 15 min without audio.
• Windows only: it’s the Volume mixer that lets you send just the game to the cable.
• AI cost: the minutes run on your own AI key, which the provider bills based on usage. You can try it first: see the free trial.
