Phone Calls for Deaf & Hard of Hearing People

Last updated: July 31, 2026

Approximately 48 million Americans — nearly 15% of the population — experience some degree of hearing loss (Hearing Loss Association of America). For most of them, phone calls aren't just inconvenient — they're a genuine barrier to getting things done. Scheduling a doctor's appointment, disputing a bill, calling a government office — all of it assumes you can hear and speak on the phone. Here's what each of the available options actually does — relay, captioned calling, your rights under the ADA — and where an AI phone agent helps, which is the waiting and the phone tree rather than the conversation.

The problem with phone calls

The world runs on phone calls. And if you're deaf or hard of hearing, that's a problem you deal with constantly.

Relay services exist, but they come with real friction. TTY relay is painfully slow — every sentence gets typed out by an operator, read aloud, then the response gets typed back to you. IP Relay and Video Relay Service (VRS) are faster, but still awkward. There's always a third person in the conversation, which means pauses, miscommunications, and a dynamic that feels nothing like a normal phone call. A relay call takes longer than a standard voice call, and some businesses still hang up when they hear a relay operator even though the ADA prohibits it.

Then there's the part nobody likes to talk about: some businesses just don't handle relay calls well. Even though the ADA requires them to accept relay calls, plenty of receptionists hang up when they hear an operator, or get impatient with the pace. It shouldn't happen, but it does.

Captioned phone services help people with partial hearing loss, but they're not perfect. Captions lag behind the conversation, miss words, and struggle with names, addresses, and numbers — exactly the details that matter most when you're scheduling something or getting instructions.

The result? Many people with hearing loss avoid phone calls entirely. They wait for email responses that never come, drive somewhere in person for something that should've taken two minutes, or just don't follow up at all. Medical appointments get postponed. Bills go unresolved. It adds up.

What an AI phone agent can take off you

Mio is an AI phone agent, and the honest description is narrower than the marketing you'll see elsewhere. Mio does not speak for you and never pretends to be you. What it does is everything that happens before a human is on the line.

You type who to call and why. Mio dials, works through the automated menu — including the speech-recognition systems that are the worst part of any call — and then holds. When a live person finally picks up, Mio calls your phone and connects you to them.

So the 45-minute wait, the "press 3 for claims," the redial after being disconnected: that part isn't yours anymore. The conversation still is, handled however you normally handle one, including with relay or captions.

Where this helps most

Calling government agencies

Social Security, the IRS, the DMV — these calls are long, complicated, and exhausting even for hearing people. Most of that length is queue, not conversation. Holding your place without you tying up a relay session for 45 minutes is the part that changes.

Insurance and billing disputes

Insurance lines put a long automated menu and a longer queue in front of a short exchange about a claim number. Getting to the front of it shouldn't cost you an afternoon.

Scheduling doctor appointments

Most medical offices still require phone calls to book, reschedule, or cancel. Front desks often answer quickly — but when they put you in a queue, you don't have to be the one monitoring it.

When relay is still the answer

If the hard part is the conversation itself rather than the wait, relay and captioned services remain the right tool, and businesses are required to accept them. Skipping the hold doesn't change how the call itself works for you — it just means you're not spending an hour to get to it.

Getting started

Getting set up takes about a minute, and none of it requires a phone call.

Mio pre-authorizes $5 on your card when a call starts. That is a hold, not the price and not a cap. What you pay is metered on the real cost of the call, so a short one comes to less than the hold and a long one can come to more — if it does, the difference goes on the same card. If Mio never gets you through, or the cost comes to under about twenty-five cents, you are not charged at all. The smallest charge is fifty cents, because that is the least a card can be charged. No subscriptions, no monthly fees.
