Blue VO!CE is a suite of filters, effects and HD audio samples to improve broadcast voice sound and increase creativity.

A vocal modulation effect, ambient sound sample, or sound effect can be toggled in a voice chat by triggering a G-Key on G HUB. These G-Keys are keys or buttons available on some Logitech devices.

1. Launch Logitech G HUB. If you don’t have G HUB, you can download it here.
2. Click on your Logitech Keyboard.
3. Click on the Assignments icon. 
   
   NOTE: If your product doesn’t have the Assignments tab then it doesn’t have a G-key.
4. Find and select a command from within the Assignments tab. Commands are located in the following sections:
   • Commands: Preconfigured system or game profile commands based on your selected G HUB Profile
   • Keys: Individual keyboard commands
   • Actions: Actions for application-specific integrations that work with Logitech G HUB
   • Macros: Custom programmable commands that perform a specific task or action
   • System: System and device control commands
   • Presets: Blue VO!CE Presets for your Blue VO!CE compatible products
   • Effects: Blue VO!CE Effects for your Blue VO!CE compatible products
   • Samples: Audio Samples for your Blue VO!CE compatible products
   • Audio: commands for your Logitech speakers
     NOTE: If you are missing some of these sections it means that you don’t have a G HUB compatible device connected with those features.
5. Select either Presets, Effects, or Samples.
6. Click on the G-key you want to give a new assignment to so it’s highlighted in blue.
   
7. Double-click on the command you want to assign to it.
   
8. Pressing the G-key will toggle the Preset, Effect, or Sample to your voice chat.
