How to Call a Deaf Person on the Phone: The Complete 2026 Guide

Calling a deaf person for the first time? Yeah, it might feel a bit weird. You’re probably wondering if you should even call, or maybe spiraling on questions like - wait, who else is going to be on this call? Will it be awkward? What do I even say? Here’s a thing: it’s not as complicated as it feels. In 2026, calling someone with any form of hearing loss is genuinely easier than it’s ever been - faster, more private, and way less mysterious once you know what options there are and how it works. Between federally funded relay service providers, video interpreters, and modern smartphone apps like Nagish, you have more options than ever, and most of them are free.

This guide walks you through every method available, when to use each one, how to handle emergency calls, and the etiquette that will make your call go smoothly.

First, A Quick Mindset Reset

Deaf and hard-of-hearing people make and receive phone calls every single day. They schedule doctor's appointments, close business deals, call their mothers, and order pizza, just like everyone else. The phone is not off-limits, and you do not need to default to a text message just because the other person can't hear.

What changes is the channel the audio travels through. Instead of sound reaching the listener's ear, it might reach their eyes as real time captions, or be interpreted into American Sign Language (ASL) on a videophone screen. The conversation is still happening in real time. You're still talking to a person, not a service.

Keep that framing in your head and the rest of this guide becomes much simpler.

The Legal Backbone: ADA and the FCC

Every method below exists because of one piece of legislation: the Americans with Disabilities Act (ADA). Title IV of the ADA required the creation of nationwide telecommunications relay services so that people with a hearing disability or speech disability could use the phone system on equal footing with everyone else. The Federal Communications Commission (FCC) enforces those rules and certifies the relay service providers that operate the system.

Translation: when you dial 711 or call someone through a relay app, you're using a federally mandated, federally funded service. The deaf person on the other end pays nothing. You pay nothing. It's a toll-free system by design.

Method 1: Dial 711 (Telecommunications Relay Services)

The simplest method, and the one most hearing people learn first, is the family of services known collectively as Telecommunications Relay Services (TRS). You dial 711 from any landline or mobile phone in the United States, and a communications assistant (CA) picks up.

Here's how it works step by step:

1. Dial 711. No area code needed. The call is toll-free.
2. Tell the assistant the 10-digit phone number of the person you want to reach.
3. Wait while the CA dials the number and briefly explains the relay process to the other party if needed.
4. Speak directly to the person you are calling. Say "How was your weekend?" — not "Ask her how her weekend was." The CA is invisible. Treat them that way.
5. Use "Go Ahead" (or "GA") to signal turn-taking. Because the CA is typing your words to a TTY user or text display, there's a slight lag. Saying "go ahead" when you've finished a thought lets the other person know it's their turn.

TRS isn't just for deaf people, it also serves people with a speech impairment who need a CA to voice their typed words. Within TRS, there are several variations you may encounter:

• VCO (Voice Carry Over): the deaf user speaks their own side of the call in their own voice, and reads typed captions of what you say. Useful for people who became deaf later in life and still speak clearly.
• HCO (Hearing Carry Over): the inverse, the user can hear your voice but types their replies, often used by people with a speech impairment.
• STS (Speech-to-Speech): the CA helps re-voice the speech of someone whose words are difficult to understand.

TRS is reliable, federally funded, and works with any mobile phone or landline you already own. The trade-off is speed and privacy: there's a real human in the middle, and the conversation moves at typing pace.

Method 2: Video Relay Service (VRS)

For deaf people whose primary language is American Sign Language, video relay service is usually the preferred method. Instead of typing, an interpreter signs your words to the deaf caller via a videophone, and voices their signed response back to you in English.

To make a VRS call:

• You call the person's specific VRS-assigned phone number directly (they'll give it to you the same way they'd give you a regular phone number).
• An ASL interpreter joins the call automatically through video conferencing software.
• You speak normally; they sign on screen; the interpreter voices the response back to you.

VRS feels closer to a normal phone call than text-based relay because ASL is a full, expressive language and skilled interpreters keep pace in real time. It's also free for the deaf user, funded through the same FCC program that supports 711.

The main thing to know on your end: just call the phone number you were given and start talking when the call connects. The interpreter will handle the rest.

Method 3: Captioned Telephones (CapTel and IP CTS)

Some people, particularly those experiencing age-related hearing loss, or who wear hearing aids and still struggle on the phone, use a captioned telephone. CapTel devices look like ordinary desk phones with a screen on top. As you speak, your words appear as live captions on the user's display while they listen to whatever residual audio they can pick up with their hearing aids.

The internet-based version, IP Captioned Telephone Service (IP CTS), does the same thing but runs over an internet connection on a smartphone, tablet, or computer. CTS in either form is one of the most popular relay categories because it preserves the user's own voice, they hear you (partially), and speak back to you normally.

From your side, a CapTel or IP CTS call is indistinguishable from a regular call. You dial their phone number, they answer, you talk. The captioning happens invisibly on their end. You don't need to do anything special, and you don't need to slow down dramatically, though speaking clearly and avoiding overlap helps the captions stay accurate.

Method 4: IP Relay and Smartphone Apps

This is where the landscape has changed most dramatically, and where modern tools have started to replace the older relay model.

IP Relay services route calls over the internet (using Internet Protocol) rather than the traditional phone network, which means they live as apps on smartphones, tablets, and laptops. The deaf user no longer needs a dedicated TTY user device or a CapTel phone, as their mobile phone is the relay terminal. All you need on either side is a working internet connection.

The standout in this category is Nagish, a smartphone app that has reshaped how millions of deaf and hard-of-hearing people make and receive phone calls. If you want the smoothest possible experience calling a deaf person in 2026, Nagish is the tool to know about.

Here's why it's different from traditional relay service providers:

It's fully on-device and private. Older relay services route your conversation through a human operator. That works, but it means a stranger is listening. Nagish uses on-device AI to convert speech to text and text to speech in real time, so the conversation stays between the two people actually on the call. For sensitive conversations like medical appointments, financial calls, and family matters, the privacy difference is significant. Nothing about the call leaves the two phones involved.

There's no perceptible lag. Because there's no human typist in the middle, captions appear almost instantly as you speak. The conversation moves at the pace of a normal phone call, not at typing speed. Hearing callers often don't realize they're on a relay call at all.

The deaf user has a normal phone number. When someone uses Nagish, they have a real 10-digit phone number you can save in your contacts. You dial it the way you'd dial anyone else. There's no separate VRS number to remember, no 711 to route through. From your perspective, you're just making a phone call.

It works both directions, and across deaf, hard-of-hearing, and speech-impaired users. Nagish handles incoming and outgoing calls. Whether the deaf person is calling you or you're calling them, the experience is the same: you speak, they read; they type or speak, you hear. People with speech disabilities can also type their side of the call and have Nagish voice it for them.

It runs on any modern mobile phone with an internet connection. No special hardware. No TTY user equipment. No dedicated videophone. Just the iPhone or Android device the person already owns.

How to actually use it on your end: you don't have to install anything. The Nagish app lives on the deaf user's phone. When you call their phone number, the app captions your voice for them, and converts their typed (or spoken) replies back to audio for you. Your job is simply to speak naturally, the way you would on any call. Nagish is increasingly the default recommendation when a deaf person sets up a phone for the first time, replacing the older patchwork of TTY users, VCO devices, and standalone CapTel hardware with a single app.

What About Emergency Calls?

Emergency services are the one place where you absolutely cannot rely on the standard 711 routing. Deaf and hard-of-hearing users should call 911 directly, either by voice if possible, by texting 911 in jurisdictions where Text-to-911 is supported, or through their preferred relay app, which routes emergency calls with location data attached.

Most modern relay apps, Nagish included, handle 911 calls intelligently: the app passes your location to emergency services and captions the dispatcher's responses in realtime. If you're a hearing person helping a deaf friend or family member in an emergency, you can dial 911 from your own phone on their behalf and stay on the line.

The National Association of the Deaf (NAD) has long pushed the FCC to expand direct 911 access for deaf callers, and as of 2026, every major U.S. carrier supports either text-to-911 or app-based emergency relay. Still, if a deaf person you know hasn't set up emergency calling on their phone, that's worth a five-minute conversation. Don't wait for the moment they need it.

Phone Call Etiquette When the Other Person Is Deaf

Tool choice matters, but so does how you behave on the call:

Speak clearly, not loudly. Whether the call is being captioned by AI on Nagish, typed by a human relay operator, or signed by an interpreter, clarity matters more than volume.

Skip the filler. Phrases like "um," "you know," and "like" get captioned along with everything else. They clutter the screen.

One person talks at a time. Overlapping speech turns into garbled text on a captioned line.

Don't ask the CA or interpreter for their opinion. They translate; they don't participate.

Text message is a fine fallback — but not the only option. Sometimes a quick SMS is the right call. But don't default to it just because you're nervous about the phone. With Nagish or another relay app, the phone is available.

Common Mistakes to Avoid

• Defaulting to text instead of calling. Use the relay or app option and call when a call is what's needed.
• Asking the relay operator personal questions about the deaf user. The CA can't and won't share that information.
• Hanging up if you reach a relay greeting. When the operator answers with something like "Relay operator 4823, may I have the number you're calling?" — that's not a wrong number. Give them the 10-digit phone number and proceed.
• Talking about the deaf person in the third person. Talk to them, not about them.
• Assuming everyone uses the same tool. Some prefer VRS with ASL. Some prefer captioned calls. Some prefer Nagish. Ask once; remember the answer.

What If You're Calling Internationally?

Most of the services above — 711, CapTel, VRS — are U.S.-funded and U.S.-only. App-based solutions like Nagish have an edge here because they ride over standard cellular and internet connection infrastructure — wherever the deaf user has a phone signal or Wi-Fi, the captioning works.

The Bottom Line

Calling a deaf person on the phone in 2026 is not a special event. It's a normal phone call routed through one of several mature, well-tested channels:

• 711 (TRS) is the universal toll-free fallback. Dial it from any phone. Includes VCO, HCO, and STS variants for users with hearing or speech disability.
• VRS is ideal when the person uses ASL as their primary language.
• CapTel / IP CTS works invisibly on your end, you just dial like a regular call.
• Nagish is the modern, app-based option that combines the speed of a normal call with the privacy of on-device AI. Increasingly the preferred choice for deaf, hard-of-hearing, and speech-impaired users in the U.S.
• 911 and emergency services should always be reached directly through Text-to-911 or a relay app like Nagish that supports emergency routing.

If you don't know which method the person prefers, dial 711 and you'll get through. If you call them often, ask. And if they use Nagish, you can stop thinking of this as a relay call at all and just dial their phone number, say hello, and have a normal conversation.

That's the real shift of the last few years: calling a deaf person used to require learning a system. Now, more and more often, it just requires picking up the phone.
