What it can actually do
Both Amazon Echo and Google Nest devices support custom voice routines. A phrase like "Alexa, call for help" or "Hey Google, emergency" can be configured to call a pre-set family member's phone, play an announcement on other speakers in the house, or — depending on the region and device — connect to emergency services directly. These routines need to be set up in advance, usually by a family member, through the Alexa or Google Home app.
The real limits
- It requires being conscious and able to speak clearly enough for the device to hear the trigger phrase — it won't help if someone is unconscious or too far from the speaker.
- It depends on Wi-Fi and power staying on, unlike a cellular medical alert device that keeps working through an internet outage.
- Range matters. A speaker in the living room won't hear a call for help from the bathroom or bedroom unless there's a device in every room where a fall is likely.
- It's not a certified medical device, so it shouldn't be the only safety plan for someone at meaningful fall risk — it works well as a backup layered with a wearable device.
- Does this cost extra beyond the device itself?
- Calling a family member's phone is typically free. Some direct-to-911 emergency calling features may require a paid service tier depending on the platform and region.
- Which is easier to set up, Alexa or Google Home?
- Both take a similar amount of setup time (10-15 minutes) through their respective apps; the better choice usually comes down to which ecosystem the rest of the person's devices already use.
