I haven't seen many landline phones with voice-dial. There are plug-in voice dialers but they have not impressed. The best voice dialers are Amazon Echo and Google Home, but then you have to upload contacts via the app on a smartphone (and she is already not happy with the idea per OP).

I like these phones for people with vision/hearing loss ($100, only difference is key color). They keys are large, brailled, high contrast. It reads back the number as you press each key. It has audio amplification and then BOOST audio amplification if needed. Don't use the BOOST if you still have your hearing.

I have used tings like these occasionally - it is a photo dialer (which can be done with tactile shapes (such as puff paint, wiki stix, marker dots, 3d printed glyphs, tape/velcro/sandpaper/hotglue) instead of photos) - it is a one-button speed dial for 12 people and works with landline phones ($70).

Thanks for all the advice. We went with getting Alexa set up, which is working well except that the sound quality for us when she speaks is very poor. But she can dial with it.

I believe Google Home and Alexa can be set to do different actions at certain verbal commands, so "call Bob" can be set to mean call his cell phone. My partner set it all up for me and I can say things like "goodnight" and it turns all the lights off.

Hi there, Im have a similar situation. My dad has very low vision and very poor hearing. He has also has a bad sense of touch and he doesn’t manage things as well as other visually impaired uncles.

The best solution that I found was the IPhone SE. It still has a button, and instead of using voice over we have voice over switched off. But we changed the settings so to pick up the phone he double taps to answer, and so the phone is automatically on speaker.

Im sure you’ll have to do some training with your mother to manage this & to teach her how to answer with double taps. (But have the voiceover stuff switched off so she doesn’t get confused with the screen talking-like saying messages,photos etc when she is using this-im sure this would confuse her like my dad)

You would have to also teach her how to press the button for Siri or go “hey Siri” and configure her voice. I found this very difficult with my father and he sometimes still a has trouble but it is a great solution if she doesn’t remember the numbers she wants to call out as you can save everyone as contacts for her.

It was extremely hard to teach my dad this, as he has been visually impaired since before iPhones really existed so it’s very confusing. But it is also a great solution if you can teach her to have something to keep her occupied for example if she likes to listen to music or something as you could put Apple Music on there for her and songs she likes and she just needs to ask for the songs. -you can also put the phone in hearing impaired mode, I’m not sure exactly what it does but I think it might help when his hearing aid is squeaking

This can still be difficult sometimes if she doesn’t have someone around every now and you might need someone to look at something for her (for example if she thumbles around a lot and accidentally changes the settings)

If there is only a short amount of numbers she needs to call something like this may be useful

If has an extra loud ringer and 6 large speed dial buttons

You could then use this tactic marker to create buttons that you think she could manage/remember/ feel

I hope this is useful for you, I understand how difficult it is to find solutions for these things. I wish there was more things available for people who have multiple impairments. If you don’t mind me asking, why has the speed dial she previously used became unmanageable? Is she more confused or having more difficultly feeling the buttons? If it’s the feel of it maybe you could still use the one she previously had that she understands and put more tactile liquid stuff on it to make her feel it better

When you say "She not technically inclined at all" and "simple to use" I can really relate to that. My Grandmother, 98 years old, had 100% hearing loss and low vision due to macular degeneration. Over the years she went from a regular phone to a TTY, but when she developed macular degeneration the text on the TTY was too small and moved to fast for her. In the early two thousands she used a simple email machine called mycidco which worked well for her, she could read and reply at her own pace. That system was discontinued. We then used a simple email web app which was also discontinued. Frustrated, I along with a friend who develops software created our own email app. It uses a simple menu system, large high contrast fonts. It works best with a large touch screen monitor and large button keyboard. It's works well for those uncomfortable with technology. Our website is $1 and there's a video which shows the concept. Hopefully it might work for your mother.
