Wake word “Ok, Nabu” triggers too frequently

[Gummi-Ente]

When using the wake word “Ok, Nabu”, the device frequently activates unintentionally. It often wakes up in response to normal background sounds or conversations. Sometimes it is enough to just say "Ok" in a sentence.
The other available wake word are even worse.

Observed Behavior:
The device frequently activates without the wake word being spoken.

Expected Behavior:
The assistant should only activate when the actual wake word “Ok, Nabu” is clearly spoken and should ignore similar or background sounds.

Additional Information:

• Version: 25.10.0
• Sensitivity: Moderate
• Environment: Living room, TV noise, background noise, calls

Note:
When lowering the sensitivity, the number of false activations decreases, but the wake word recognition becomes significantly less reliable.

My Television is always triggering the activation word without saying "Ok, Nabu" once.
