well I had some long conversation with the culprit Gemini himself. It is possible if they enable it but as in googles terms would feel sluggish.
Here is a comprehensive summary of the issue, the technical reasons behind it, and the working solutions.
Issue: "Hey Google" is Disabled/Fails when Gemini is set to Finnish on Pixel 10
The Scenario:The user wants to keep the phone’s voice recognition trigger ("Hey Google") active—potentially in English—but have the Gemini Assistant listen and respond in Finnish. Currently, Google disables the wake word entirely when Finnish is selected, or fails to hand off the command if languages are mixed.
The Technical Explanation (Why Google hasn't fixed this)
1. The "Two Brains" Conflict (DSP vs. CPU)The phone uses a low-power chip (DSP/Dumb Brain) to listen for the wake word to save battery. It hands off data to the main processor (Gemini/Smart Brain).
The Failure: If the DSP is set to English, it expects English grammar immediately following the wake word to verify the request. When it hears Finnish (e.g.,
"Soita vaimolle"), it interprets the phonetics as gibberish/noise and cancels the request before Gemini even gets the message.
2. The "False Positive" Risk (The "Hei" Problem)Google likely disables the wake word in Finnish environments because the English model is not trained to filter out Finnish background noise.
The Risk: In Finland, the word "Hei" (Hello/Hey) is used constantly. Without a specific Finnish acoustic model for the DSP, the phone would likely wake up accidentally dozens of times a day (e.g., hearing
"Hei, kuule" as
"Hey Google"), leading to battery drain and privacy concerns.
3. Latency Standards (Cold Start)Technically, the phone
could verify "Hey Google" in English, pause, switch languages, and then open Gemini in Finnish.
The Barrier: This "context switch" takes roughly 1000ms–2000ms. This delay would cause the phone to miss the first word of the user's command unless the user paused awkwardly. Google considers this "laggy" behavior a poor user experience and disables the feature instead.
The Solutions
Solution A: The Physical Bypass (Official & Reliable)
Bypass the "listening" chip entirely and manually trigger the "Smart Brain."
Method: Go to
Settings > System > Gestures > Quick Tap. Set it to "Access your digital assistant."
Result: Double-tap the back of the phone -> Gemini opens -> Speak Finnish immediately.
Solution B: The "Smart Home" Loophole (For Lights/IoT)
If the goal is controlling smart home devices:
Method: Keep the Assistant language in English. Rename devices in the Google Home app to Finnish names (e.g., name a light "Valot").
Command: Say
"Hey Google, turn on Valot." (English trigger + Finnish device name).
Solution C: The "Golden Key" (Hands-Free Automation)
Use a third-party app to replace the "listening" function while keeping banking apps safe.
Tools: MacroDroid (Recommended/Easier) or
Tasker.
The Setup:
Install the automation app and a
Hotword Plugin (e.g., form the Play Store or GitHub).
Train the plugin to listen for a custom sound (e.g., "Hei Computer").
The Critical Step for Banking Apps: Do
not use "UI Interaction" actions (which require Accessibility Services that block banking apps).
The Action: Configure the app to send the Android Intent
Result: The plugin hears your voice and sends a system signal to launch Gemini in "Listening Mode" immediately. This works hands-free and does not violate banking app security policies.
