Limited English Proficiency on Emergency Calls: Overcoming Language Barriers in Public Safety

A dispatcher hears a woman screaming a street name she can't quite make out, then a word in a language he doesn't speak. An officer arrives at a disturbance where the only person who speaks English is a nine-year-old. A paramedic asks a patient, "Any allergies?" and gets a polite nod that could mean yes, no, or "I didn't understand."

Every public-safety agency handles calls like these. When someone has limited English proficiency (LEP), the usual tools of the job, like questions, instructions, and reassurance, stop working the way they should. This guide covers what miscommunication costs, how to use interpreters well, how to check understanding, and how agencies can build lasting capacity for police, fire, EMS, and 911.

This article is general information, not legal advice. Federal language access guidance changed in 2025 and 2026 and may continue to change, and many states and cities have their own requirements. Follow your agency's language access policy and consult your agency's attorney about your obligations.

Who Has Limited English Proficiency?

People with limited English proficiency are generally defined as those who speak English less than "very well," the category used by the U.S. Census Bureau. The numbers are large. According to the Census Bureau, 67.8 million people in the United States spoke a language other than English at home in 2019, almost 1 in 5 residents. Among Spanish speakers, 39% spoke English less than "very well," and that figure was 52% among Chinese speakers and 57% among Vietnamese speakers (U.S. Census Bureau).

Many of those residents speak enough English for everyday life. But stress, fear, pain, and unfamiliar vocabulary can erase that ability during an emergency. Someone who handles a grocery store fine may not be able to describe chest pain or a suspect's clothing.

The Cost of Miscommunication

When responders and residents can't understand each other, the effects show up fast.

In policing

A Vera Institute of Justice and COPS Office report put it plainly: "Without dialog, police cannot effectively conduct investigations, build community trust, or ensure that victims will report crime." The report adds that people who can't communicate easily with police "may not report crime, assist officers in criminal investigations, or partner with an agency to advance community policing" (COPS Office and Vera Institute).

In EMS and healthcare

Language barriers in healthcare carry measurable risks. In a 2007 study of hospital adverse events, 49.1% of events involving LEP patients caused some physical harm, compared with 29.5% for English-speaking patients. LEP patients' adverse events were also more likely to result from communication errors (52.4% vs. 35.9%). The authors concluded that "language barriers appear to increase the risks to patient safety" (Divi et al., 2007). While that study looked at hospitals, the same risks apply to a patient assessment in the back of an ambulance.

Using Interpreters and Language Lines Well

Be careful with ad hoc interpreters

In an emergency, you use what you have. But the COPS report warns: "Being bilingual does not mean someone is able to interpret." Trained interpreters act as a conduit and do not "edit, add, subtract, or modify what is said."

Family members, neighbors, and especially children create real problems:

They may soften, skip, or change what’s said to protect someone.
They may be involved in the incident, including as a suspect or a victim.
Children may be exposed to details that harm them, and adults may not speak freely in front of them.

Use a family member or bystander only for immediate safety needs, then switch to a qualified interpreter or language line as soon as you can. Follow your agency's policy on when that's permitted.

Get the most out of a language line

Telephone and video interpretation services let a responder reach an interpreter in minutes. A few habits make those calls work better:

Speak to the person, not the phone. Look at them and say “you,” not “tell her that…”
Use short segments. One or two sentences at a time, then pause.
Avoid jargon and acronyms. “Did you lose consciousness?” is easier to interpret accurately than “Any LOC?”
Ask the interpreter to interpret everything. Including side comments and anything the person says to others.
Brief the interpreter when you can. “This is a domestic violence call. The caller may be afraid to speak in front of her husband.”

Plain Language and Checking Understanding

Even with an interpreter, and certainly without one, plain language is your best tool.

Instead of this	Try this
“Are you experiencing any shortness of breath?”	“Is it hard to breathe?”
“We need you to exit the vehicle.”	“Please get out of the car.”
“The suspect fled the scene on foot.”	“Did he run? Which way?”
“Do you understand?”	“Tell me what you will do next.”
“We’re going to transport you to the ED.”	“We are taking you to the hospital now.”

Use teach-back instead of "Do you understand?"

Most people answer "yes" to "Do you understand?" whether they do or not. The Agency for Healthcare Research and Quality (AHRQ) recommends the teach-back method: "checking understanding by asking patients to state in their own words what they need to know or do." AHRQ notes that yes-or-no questions like "Do you understand?" are not teach-back questions, and suggests a "chunk and check" approach of confirming understanding throughout the conversation instead of only at the end (AHRQ).

For responders, teach-back might sound like:

“I want to make sure I explained this clearly. Where will you go if the smoke comes back?”
“Tell me in your own words what the detective will do tomorrow.”
“Show me how you’ll use the inhaler.”

Cultural Factors That Affect Trust

Language is only part of the picture. Some residents may come from places where contact with police or government brought trouble, and that history can shape how they react to a uniform. The COPS report notes that refugees from some countries arrive "unfamiliar with U.S. customs and norms, including criminal justice and police practices."

Other cultural factors can shape a call: who in a family speaks for others, beliefs about illness and death, discomfort with a responder of a different gender, or fear about immigration status. You don't need to be an expert in every culture. You do need to avoid assumptions, explain who you are and why you're there, and ask respectful questions: "Is there someone you'd like with you?" "Is there anything I should know about how your family would like this handled?"

Small efforts matter. In the COPS report, a community advocate said, "Having officers speak some Spanish opens the door to more communication."

Nonverbal Communication

When words fail, the rest of your communication carries more weight:

Tone and pace. A calm, slower voice signals safety in any language. Talking louder doesn’t help.
Posture and space. Keep your hands visible and relaxed, and give people room when safety allows.
Gestures and visuals. Pointing, pictures, and simple drawings can help. Be aware that some gestures mean different things in different cultures.
Watch for false agreement. Nodding and smiling can mean “I’m being polite,” not “I understand.” That’s exactly when teach-back matters.

Building Agency Capacity for Language Access

Good language access doesn't happen call by call. It takes planning. The COPS and Vera report recommends that agencies "develop a formal written policy for serving LEP individuals" and profiles practical approaches:

Testing bilingual staff. Oklahoma City police used a standardized oral proficiency test to rank officers’ language skills, so the most fluent officers handled the most sensitive conversations, such as interrogations.
Field interpreters. Las Vegas Metro used part-time Spanish interpreters equipped to respond in the field around the clock.
Community partnerships. Boise partnered with refugee resettlement agencies to identify language needs and recruit interpreters.

Other steps to consider include tracking which languages your calls involve, making sure every unit and dispatcher knows how to reach your language line quickly, translating key forms and victim information, and training staff on working with interpreters.

A note on the legal picture: for years, federal guidance under Title VI and Executive Order 13166 shaped agency language access programs. In July 2025, the U.S. Attorney General issued a memo implementing an executive order designating English as the official language and rescinding prior federal LEP guidance (U.S. Department of Justice). Title VI itself remains law, and state and local rules vary, so check with counsel before changing your program.

Why Practicing These Conversations Out Loud Matters

Plain language sounds easy until you're under pressure. Under stress, responders fall back on the jargon they use every day with coworkers. "Do you understand?" comes out automatically. Talking through an interpreter feels awkward the first several times, and on a real call, awkward can mean slow.

Rehearsal fixes that. Practicing short, plain sentences, pausing for interpretation, and using teach-back out loud builds the habit before it's needed. Role-play with a partner who has limited English (or who plays a caller who only nods) quickly reveals how much jargon slips into everyday instructions.

Key Takeaways

Limited English proficiency affects a large share of residents, and stress makes language barriers worse during emergencies.
Miscommunication hurts investigations, community trust, and patient safety.
Use qualified interpreters and language lines whenever possible. Avoid relying on children and family members except for immediate safety.
Speak plainly, in short segments, and confirm understanding with teach-back instead of “Do you understand?”
Build agency capacity with a written policy, tested bilingual staff, community partners, and regular practice.

Conversations like these deserve practice. Foretell AI from Glimpse Learning lets responders rehearse calls privately by speaking with a lifelike AI avatar who has limited English. Rubric-based feedback scores their use of plain language and confirmation techniques like teach-back, so clear communication becomes a habit before the next call.
