When the Senses Begin to Fade: What Alexa & Co. Can Help With

The following tasks can either be handled by voice assistants like Alexa on their own or require additional tools. In most cases, however, these tools are already affordable and easy to set up.

We took a look at which basic tasks can be accomplished with Alexa & Co:

• When vision declines

For people with limited vision, the biggest benefit is that they no longer have to read anything—they can simply listen to everything. Upon request, Alexa reads the news aloud, tells the time, reminds you of appointments and medication, and answers questions without requiring you to reach for a calendar or newspaper.

On devices with screens—the so-called Echo Show models—there’s also a screen magnifier that lets you enlarge content, as well as a read-aloud feature for displayed text. This keeps many things accessible that would otherwise be difficult or even impossible.

• When hearing is difficult

There are also useful features for people with hearing impairments. On devices with a screen, you can enable subtitles so you can read along with Alexa’s responses. One particularly convenient feature is that, on some devices, the audio can be transmitted directly to modern hearing aids, delivering movies, music, or audiobooks in high-quality sound directly to the ear. For many, this makes a noticeable difference compared to a speaker, whose sound quickly fades into the room.

• If mobility is limited

If mobility is limited, voice control is a true game-changer. Turning on the lights, adjusting the heat, calling someone, or getting help: You can do all of this just by using your voice—without getting up or picking up a device. When paired with smart outlets or lights, you can conveniently control a large part of your home from the comfort of your armchair or bed.

With smart locks, seniors can decide who has access to their home—even from their hospital bed. For more information, here’s an interview with a security expert on how to choose these locks and set up a security plan. And for people who speak more slowly or with pauses, there’s an “adaptive listening” setting that gives Alexa more time before expecting a response.

These tasks require smart plugs or smart locks, which—in the case of Alexa, for example—can be purchased online or at well-stocked specialty stores. The easiest way to set up a smart home is to look for compatible products. You can find these for Alexa on Amazon, and other solutions at well-stocked specialty stores.

Support for People with Dementia

Especially in the early stages of dementia, a voice-activated assistant can help structure the day: Regular reminders about meals, medications, or appointments—always at the same time and in a calm voice—provide stability. However, how effective the technology is depends heavily on the stage of the disease. In the early stages, many people can operate the devices themselves after a little practice; as the disease progresses, this becomes more difficult because, for example, they can no longer remember the activation word.

This makes it all the more important for a family member to set up the device and keep its operation as simple as possible. Over time, the functions can be adapted to the person’s condition—for example, by limiting the device to a few fixed voice commands and some familiar routines, such as daily meal reminders. In this way, the tool helps rather than adding to the confusion.

Amazon, in collaboration with the German Alzheimer’s Association and the Red Cross, investigated how these devices can help relieve the burden on people with dementia and their families. The feedback was positive, especially regarding the sense of connection and reduced loneliness. The following five features were particularly well-received in practical testing: Reminders for appointments and important tasks made it easier to organize daily life and helped relieve the burden on family members and caregivers. Music encouraged physical activity, and familiar images helped improve focus. Conversations with Alexa provided opportunities for conversation, and the ability to independently access knowledge and information was seen as motivating.

Added to this was the ease of voice control: features such as the alarm clock, phone, or radio could be used without having to press buttons or navigate through menus. This makes it possible to do many things at one’s own pace that would otherwise require assistance from others.

Safety First

As helpful as Alexa is, it’s just as important to consider privacy. By its very nature, a device like this is always listening, as it constantly waits for the wake word—such as “Alexa!”—to respond. For users in Germany and Austria, voice commands are processed in the cloud—that is, on the company’s servers located outside the country. Local processing directly on the device was never an option here anyway. In the U.S., Amazon had offered such an option for certain models, but discontinued it in March 2025 because the new AI features associated with Alexa+ require more computing power than an Echo device can provide on its own.

Here’s what you can and should do: In the Alexa app, you can enable a setting that prevents recordings from being permanently stored after they’ve been processed. In the Privacy Dashboard, you can also view what has been recorded and delete it. And as a practical matter, you should carefully consider where in the house to place such a device: A listening microphone is less appropriate in the bedroom or in places where confidential conversations take place than, for example, in the kitchen.

Family members bear a special responsibility when setting up such a device for a person with dementia who may no longer be able to give informed consent to data processing. In such cases, it is important to make decisions in the best interest of the person concerned, to activate only what is necessary, and, when in doubt, to use functions that continuously collect data sparingly.

Please always keep in mind: As helpful as this technology is, it is no substitute for human care. A voice assistant should provide support, not patronize, and also requires a stable Wi-Fi connection as well as mindful handling of the collected data. Those who keep these requirements in mind will find voice assistants to be an affordable addition that integrates well into everyday life.

Check for softer voices

“Alexa, turn on the light in the bedroom”: For a command like this to make daily life easier, the technology must also be able to understand older adults whose voices have become softer or whose speech patterns have changed. Voice control must be designed to accommodate different speaking styles so that the very people who rely on assistance can use it. It’s also important to note that, in an emergency, a person’s voice may become higher-pitched. Please test the devices in everyday use with different voice pitches to see if they recognize the voice.

A research study published in 2026 examined this requirement using voice recordings from 83 English-speaking older adults. They had read aloud predefined Alexa commands. Significantly more recognition errors occurred among people with dementia than among those without cognitive impairment. By contrast, no significant difference was found between the group with mild cognitive impairment and the control group. Volume and voice quality were also correlated with recognition accuracy.

Our Conclusion

Alexa can be a great help to older adults and their caregivers and loved ones because the device steps in exactly where vision, hearing, mobility, or memory reach their limits. Of course, it’s no substitute for human care, but it restores a measure of independence, and that’s worth a great deal.

Use it thoughtfully, carefully configure the privacy settings from the start, and choose its location wisely. Then the benefits will outweigh any concerns, without compromising privacy.
