Requirements:
- Interop Tools 1.9 — Download Link
- Hey Cortana Registry File — Download Link
Caution:
- This is a community-developed tweak and is not officially supported by Microsoft. Use it at your own risk.
Step-by-Step Instructions
Method 1: Using the Registry File (Recommended)
- Uninstall any previous version of Interop Tools you may have installed, then install Interop Tools 1.9.
- Open Interop Tools after installation.
- Navigate to This Device.
- Press the Windows button to minimize Interop Tools and exit to the Start screen.
- Open the downloaded heycortana.itreg file from File Explorer.
- Interop Tools will open automatically and prompt you to import the registry entries — tap the Import button.
Method 2: Manual Registry Configuration
If you prefer to do it manually, navigate to the following registry path and set the values as specified:
Registry Path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech_OneCore\AudioPolicy
Registry Type: Integer
Values to set:
| Value Name | Data |
|—|—|
| Duplex | 2 |
| HardwareVoiceActivationInSKU | 0 |
| SoftwareSpeakerIDInSKU | 1 |
| SoftwareVoiceActivationInSKU | 1 |
| VoiceActivationAlwaysUseHWKWS | 1 |
| VoiceActivationEnableWoV | 1 |
Activating Hey Cortana
- Open Cortana and go to its Settings.
- Turn on the Hey Cortana option.
- Say “Hey Cortana” aloud. Your phone should respond and start listening for your voice commands.
- If it doesn’t work on the first try, manually tap the microphone button and give a voice command. Try saying “Hey Cortana” again afterward — it should start responding automatically from then on.
Notes
- The Hey Cortana feature was previously exclusive to high-end Lumia devices such as the Lumia 950. After applying this tweak, it will be available on any Windows Phone device.
- Battery warning: It is recommended to keep this feature disabled when not needed, as it consumes a significant amount of battery power due to continuous voice listening.
