If a Google Home or Nest speaker ignores a basic command, first check whether it reacts to “Hey Google” or “OK Google.” No reaction usually points to power, a muted microphone, wake-word sensitivity, an update, or a connection problem. If it wakes but cannot carry out the request, check the active assistant, command wording, Digital Wellbeing, language, account settings, and the service or device you asked it to control.
Work through the checks below in order. Start with the specific speaker that is failing; settings such as microphone mute and wake-word sensitivity are device-specific, while language and some home-level restrictions can affect more than one device.
First check which assistant your home is using
Google is rolling out Gemini for Home voice assistant in early access. Availability is home-by-home, so being in a supported country or owning a compatible device does not guarantee that a particular home has access. In the United States, Google lists English (United States) and Spanish (US) among the supported early-access languages. See Google’s Gemini for Home availability and requirements.

The voice names provide another clue: Google Assistant voices are named as colors, while Gemini voices use plant or similar names, such as Red and Pothos. Gemini for Home requires Google Home app version 4.1 or later, Cast firmware 3.76 or later for speakers, and Fuchsia firmware 28 or later for displays. Google’s June 2, 2026 release notes say app version 4.18 introduced improvements, including more responsive alarm, timer, and reminder commands (release notes).
If the speaker does not react to “Hey Google”
Use the wake phrase as “Hey Google, [command]” or “OK Google, [command].” If there is no visible or audible activation, check power and the microphone before changing command wording. Google’s wake-word troubleshooting steps recommend checking whether other questions work as well.
- Check the microphone switch. Most Nest speakers have it on the back or side; the original Google Home has a mute button on the back; Nest displays have a switch on the back. The Google Home Speaker (2026) has a switch on the bottom near the power cord. Its light ring is solid orange when the microphone is off.
- Look for the wake-word indicator. Most smart speakers show top LED dots spinning or blinking; Nest displays show four colored dots at the top of the screen; the Google Home Speaker (2026) glows solid white around its light ring when activated.
- Check whether it is updating. A slowly spinning white light generally means an update is in progress. During an update, the device cannot answer questions or execute commands. Google says an update typically takes up to 10 minutes; do not unplug the device or change its Wi-Fi settings while it downloads (update guidance).
Adjust wake-word sensitivity
If the device sometimes misses the wake phrase, change sensitivity for that device:

- Tap Home settings.
- Tap Gemini for Home voice assistant or Google Assistant, whichever is active.
- Tap “Hey Google” sensitivity, select the device, and choose a sensitivity level.
The setting applies to anyone using that device. It does not decide which speaker responds when multiple devices hear the same phrase. See Google’s sensitivity instructions.
If it wakes but mishears you
Ask, “Hey Google, repeat the question.” Then try speaking more slowly or rephrasing the request. If it activates reliably but repeatedly fails a particular task, continue to the relevant command or account check below rather than treating it as a wake-word problem.
Check internet access and Wi-Fi
Ordinary voice commands need a working internet connection so the speaker can receive the assistant’s response. Confirm that the speaker is online in Google Home and that the router or internet service is working (connection requirements).
A phone and speaker do not have to stay on the same Wi-Fi network for every voice command. The same network or a linked Google Account is mainly relevant when setting up the device, using app controls, or checking its settings. When troubleshooting through the app, make sure the phone is using the Google Account linked to the home (Google’s voice-command guidance; reboot instructions).

Common reasons a speaker goes offline
- A new router, changed Wi-Fi name or password, or router settings changed after an update.
- An ISP outage, weak signal, or a speaker too far from the router.
- A public, university, hotel, shared-building, or other captive-portal network.
- An incorrectly entered Wi-Fi password; passwords are case-sensitive.
During setup or troubleshooting, Google recommends placing the speaker or display approximately 15–20 feet from the router and trying both 2.4 GHz and 5 GHz bands on a dual-band router. If it connects to a temporary phone hotspot but not the home network, the likely problem is the home modem, router, ISP, or network configuration—not necessarily the speaker. Google says hotspots are not fully supported for normal Nest or Home use. Details are in Google’s Wi-Fi troubleshooting guide.
Check Downtime and other restrictions
Digital Wellbeing can make a working speaker appear unresponsive. When Downtime is active, devices do not respond to most commands or questions; commands to stop or cancel activities still work. Automations generally do not run unless they started before Downtime began. Google also notes that Filters or Do not disturb may restrict features, but Do not disturb should not be confused with Downtime: Google specifically documents Downtime as the setting that causes devices to ignore most commands.
- Open Google Home and tap your profile picture or initial.
- Tap Home settings.
- For Gemini for Home, tap Parental controls & Digital wellbeing; for Google Assistant, tap Digital wellbeing.
- Review Downtime and any filters that could affect the command.
Google’s current path is documented at Digital Wellbeing settings, with Downtime behavior explained here. Its voice-command guidance also covers restricted commands and features.
Make sure the command is in a supported language
In Google Home, open Profile picture or initial > Home settings > Google Assistant or Gemini for Home voice assistant > Languages. Tap Add a language, then tap the current language to choose another. Google Assistant can recognize two languages; Gemini for Home documentation allows up to three in the applicable configuration. Neither should be expected to understand two different languages mixed in a single phrase—for example, “Hey Google, set a timer for drei Minuten.”
Changing the assistant language affects all Google Home and Nest devices linked to the account, and language availability varies by device, region, and country. See Google’s language instructions.
When personal requests fail but ordinary ones work
Commands for a calendar, Gmail, Google Photos, private YouTube playlists, or personal YouTube Music content depend on personal access. If general questions work but these requests fail or return the wrong information, check that the correct Google Account is selected, Personal results are enabled, and Voice Match recognizes you.
Enable Personal results for the home or device
- In Google Home, tap your profile picture or initial.
- Tap Home settings, then Google Assistant or Gemini for Home voice assistant.
- Tap Personal results and edit the home or individual-device setting.
If Voice Match is turned off after Personal results was enabled, Google automatically turns Personal results off. The setting is described at Google’s Personal results help page.

Tap your profile picture or initial in Google Home to verify or switch accounts. A different account can mean the speaker looks in the wrong calendar, music library, list, subscription, or personal media collection (music account help; account guidance).

Use clear, supported command forms
Begin with the wake phrase, then state one task plainly. Google provides the following examples for common requests in its voice-command guide.
Alarms and timers
- “Hey Google, set alarm for 6 AM tomorrow.”
- “Hey Google, set an alarm for 7 AM called Medicine.”
- “Hey Google, set alarm for 7 AM every day of the week.”
- “Hey Google, what alarms are set?”
- “Hey Google, cancel my medicine alarm.”
- “Hey Google, set a timer for one minute.”
- “Hey Google, set a 10-minute timer for pizza.”
- “Hey Google, how much time is left on my pizza?”
- “Hey Google, cancel pizza timer.”
For Google Assistant, timer commands also include pause, resume, and restart. Gemini for Home examples include “set a timer for 30 minutes,” “cancel the sleep timer,” and “how much time is left on the sleep timer?” A sleep timer belongs to the device where it was created, and only one sleep timer can be set per device. In English, say “Stop” to stop a ringing alarm or timer; the wake phrase is not required to stop a ringing alarm.
Smart-home controls
Use “turn on [device name],” “turn off [device name],” or “set [device name] to [value].” Examples include “Hey Google, turn on the kitchen lights,” “Hey Google, turn on the bedroom fan,” and “Hey Google, set the thermostat to 68 degrees.” The device must already be added to Google Home, and third-party devices need a supported integration (supported device and service guidance).
Music and playback
Try specific forms such as “Hey Google, play [song name] by [artist name],” “play [song name] on [music service],” “pause,” “resume,” “next song,” “what’s playing?” or “set volume to 40%.” Google lists these forms in its music command guide.
If a music request does not play the song you asked for
The music service must be supported where you live and linked in Google Home. To set the default provider, open Google Home > Profile picture or initial > Home settings > Music, then select the provider.
Exact-song playback can depend on the provider and subscription. Spotify generally requires Premium for most functionality; YouTube Music generally requires YouTube Music Premium or YouTube Premium for most functionality; Apple Music requires an Apple Music subscription. Free or base versions of YouTube Music, Spotify, and Pandora may play an artist or song radio station rather than the exact requested track. The outcome also depends on location, linked account, and command, so an exact-song request is not guaranteed on a free tier. See Google’s provider and playback details.

If a smart-home device does not respond
A device working in its manufacturer’s app may still fail through Google Home if the manufacturer’s service was never linked, has lost authentication, or is unavailable in your region. Check the partner in Google Home:
- Tap Add.
- Tap Link apps or services.
- Tap Works with Google.
- Search for the smart-home partner.
Google explains linking and availability at Works with Google setup. Also check that the command names the right device and room and that you have selected the right home. Ambiguous names, room assignments, device types, or unassigned devices can cause a command to target the wrong thing. Google’s 2026 Gemini update notes describe improved handling of multiple homes, room-wide commands, unassigned devices, and names that do not include words such as “light” (release notes).
Reboot after a stalled update or temporary fault
A reboot is a safe next step when a device is online or updating unusually long; it is not a factory reset and normally preserves configuration. If an update has taken more than 20 minutes, Google’s sequence is to reboot the speaker, reboot the router, and factory-reset only if necessary (update recovery).
Reboot from the Google Home app
- Confirm the phone or tablet and speaker or display are linked to the same account.
- Open Google Home and tap Home.
- Tap All devices.
- Touch and hold the device tile, then tap Settings.
- Tap More, then Reboot.
Alternatively, unplug the power cord, leave the device unplugged for one minute, then reconnect it. Both reboot methods are documented at Google’s reboot instructions.
Factory-reset only as a last resort
A factory reset erases device data, disconnects the device from home members, and cannot be undone. Google does not support resetting a speaker or display by voice or in the Google Home app; reset uses physical controls. Unplugging only reboots the device and normally leaves its configuration intact. Before proceeding, identify the exact model and follow its specific controls in Google’s reset guide.
- Google Home Speaker (2026): Turn the microphone off and press and hold the top center. After about 5 seconds reset begins; continue holding for about 10 more seconds until the confirmation sound.
- Nest Audio: Turn the microphone off and press and hold the center near the top; keep holding after reset begins until the confirmation sound.
- Nest Mini (2nd gen): Turn the microphone off and press and hold the center where the lights are.
- Google Home Mini (1st gen): Press and hold the factory-reset button on the bottom, below the power cord.
- Google Home Max: Press and hold the factory-reset button near the power cord for about 12 seconds.
- Original Google Home: Press and hold the rear microphone mute button for about 15 seconds.
- Nest Hub or Nest Hub Max: Press and hold both rear volume buttons for about 10 seconds.
When to contact Google
If the device has power, hears the wake phrase, is online, is not muted or in Downtime, and still fails to answer, Google’s recommended escalation is to submit a feedback report through the Google Home app rather than immediately factory-resetting it. Follow the reporting step in Google’s wake-word troubleshooting guide.
