AI Phone Calls for Deaf & Hard of Hearing People

Last updated: March 19, 2026

Nearly 48 million Americans experience some degree of hearing loss (Hearing Loss Association of America). For many of them, making a phone call means relying on relay services that are slow, awkward, and frequently misunderstood by businesses on the other end. Mio is an AI phone agent that takes a completely different approach: you type what you need, Mio calls with a natural voice, and you get a written summary when it's done.

The problem with phone calls

Phone calls are still the default way the world handles appointments, insurance claims, government services, and billing questions. If you're deaf or hard of hearing, every one of those calls requires navigating a system that wasn't built for you.

Relay services — TTY, IP Relay, Video Relay Service — were designed to bridge the gap. And they helped. But they introduced problems of their own. Every call involves a third-party operator who listens to the entire conversation, types or signs what's being said, and relays your responses. It's slow. It's awkward. And it strips away any sense of privacy or normalcy from what should be routine calls.

The FCC's own data shows that relay calls take 2-3x longer than standard voice calls. Worse, many businesses still hang up when they hear a relay operator, even though the ADA explicitly prohibits this. The experience can feel defeating — you're doing everything right, and the system still fails you.

Captioned phone services help if you have partial hearing, but captions lag behind the conversation, miss key details like names and numbers, and don't help at all if you can't speak on the phone.

How Mio works

Mio is an AI phone agent. The entire interaction on your end is text-based. No voice input required. No hearing required.

You message Mio the way you'd message a friend: "Call my dentist at 555-0192 and reschedule my cleaning to sometime next week, afternoons preferred." Mio makes the call immediately using a natural-sounding AI voice. The person answering the phone has a completely normal conversation — they have no idea an AI is calling on your behalf.

When the call is done, you get a detailed written summary: the appointment was moved to Thursday at 2:30 PM, bring your new insurance card, arrive 10 minutes early. Everything captured in text you can read, save, and reference later.

There's no operator in the middle. No one listening to your private medical or financial details. No "go ahead" pauses. No explaining to a confused receptionist how relay works. Just the results you need, delivered the way you want them.

Real use cases

Doctor appointments and medical offices

Most medical offices still require a phone call to schedule, reschedule, or cancel. Many patient portals are limited. Tell Mio the office number, your preferred times, and the reason for the visit. Mio handles the scheduling conversation and sends you every detail in writing.

Insurance and billing

Insurance calls are long, detail-heavy, and full of claim numbers, policy terms, and specific dollar amounts — exactly the kind of information that gets garbled through relay. Mio captures everything accurately and gives you a full record to review.

Government agencies

Social Security, USCIS, the DMV, the IRS. These calls often involve long hold times followed by complicated conversations. Mio handles the hold, navigates phone trees, talks to the representative, and brings you back the information you need — all without you sitting on hold with a relay operator for 45 minutes.

Restaurant reservations and local businesses

Not every restaurant or small business has online booking. Sometimes the only way to make a reservation or ask about hours is to call. Text Mio the details and it handles the rest.

Why Mio is different from relay services

• Completely private. No human operator hears your conversations. Your medical, financial, and personal details stay between you and the AI.
• Faster. No relay lag. Mio has a real-time conversation at natural speaking speed.
• Invisible to the other party. Businesses hear a normal voice. No hang-ups, no impatience, no explaining how the service works.
• Full written record. Every call produces a detailed text summary you can reference anytime.
• Works with any phone number. Doctors, government lines, businesses, personal numbers — if it rings, Mio can call it.
