Is the emergency alert voice generator free?

Yes. Every visitor gets 3 free generations a day of up to 300 characters, with no account — enough for a short bulletin. Signed-in users spend credits on scripts up to 2,000 characters and the Cinematic engine.

How do I make an EAS scenario voice for a fictional video?

Invent the agency, the town and the hazard, write plain instructions, then voice them here with Broadcast on Analog at 50%; this EAS voice generator makes speech only, never alert tones. Don’t add the real EAS Attention Signal or SAME header tones: under FCC rules (47 CFR 11.45), no one may transmit the EAS codes or Attention Signal, or a recording or simulation of them, outside actual emergencies, authorized tests and a few listed exceptions. Design your own tone that sounds nothing like them.

Can I use an emergency alert voice in my horror video?

Yes, for clearly fictional content. Our Terms of Service allow your own projects, monetised videos and games included. Never use it to impersonate a real authority or to frighten someone who has not agreed to it.

Is it illegal to make a fake emergency alert?

Writing a fictional broadcast for a story is ordinary creative work. Spreading something people could mistake for a real alert is different: it can cause real panic, and many places have rules against false alerts. This is not legal advice — keep the audio inside the project it was made for.

What voice is used for emergency alerts?

Real alert systems have used various synthetic and recorded voices; we copy none of them. Broadcast is an original preset with a flat, steady cadence. Overlord adds colder authority, Undertaker a deeper read.

How do I keep emergency alert text to speech easy to follow?

Stay near 50%, keep sentences short and write numbers as words. Above 70% the band narrows and the clipping grows — right for a failing signal, wrong for the bulletin itself.

Emergency alert voice generator

Emergency Alert Voice Generator

This emergency alert voice generator is built for broadcasts that never happened: the warning in your horror short, the radio in your game’s safe room, the voicemail in your ARG. Type the bulletin, keep the steady Broadcast voice, and a lighter Analog setting adds a narrow radio band while every instruction stays clear. For fiction only — never for anything that could pass as a real alert.

Script ideas

Fictional emergency broadcast scripts

A good fictional alert is dull on purpose: who is speaking, what is happening, what to do. The horror lives in one instruction that makes no sense, read as calmly as the rest. Invent the town, the agency and the station, so the broadcast can only be heard as fiction. Each script below loads straight into the emergency alert voice generator.

01Shelter in place

“A shelter-in-place order is now in effect for Greywater County. Close all windows. Turn off ventilation. If you hear knocking, it is not the rescue team. The rescue team does not knock.”

Keep intensity at 50% so every instruction stays intelligible.

02Eyes on the ground

“The Lantern Valley Observatory advises that the object above the northern horizon is not the moon. Do not look at it. If you have already looked at it, stay where you are. Someone will come for you.”

Pair it with a slow push-in on an empty sky.

03The test that goes wrong

“This is a scheduled test of the civil defense warning system. No action is required. This is not a scheduled test. Do not take any action. Do not make a sound.”

Render the last two sentences again at 80%.

04Curfew notice

“By order of the Halden Township Council, a curfew is in effect from sunset. Porch lights must stay off. If you see a neighbor walking after dark, do not call out. It is not your neighbor.”

Overlord makes the council sound like it enjoys the order.

05Water advisory

“Boil-water notice for the eastern district. Do not drink from the tap. If the water from your tap is warm and moving on its own, leave the house. Do not go back for belongings.”

A mundane notice that turns wrong beats an obvious disaster.

06The final update

“This is the final update from this station. All staff have been evacuated. This message will repeat automatically. If you hear it after the third day, the station is not empty.”

Undertaker gives a heavier, slower last broadcast.

Effect recipe

How the emergency broadcast sound is built

As an emergency broadcast voice generator, this page runs the Analog effect at a lighter 50%, so the voice stays easy to follow. It runs live in your browser through the Web Audio API:

Broadcast

1
Radio band
510 Hz – 3 kHz
The boxy sound of a radio or TV announcement, with enough top end left for crisp consonants.
2
Light grit
waveshaper drive 50
Enough saturation to sound transmitted rather than recorded in a booth, not enough to smear words.
3
Announcer leveling
compressor −24 dB, 8:1
Each syllable comes out at nearly the same volume, the unhurried delivery of an official bulletin.
4
Carrier hiss
noise at 2.5 kHz, gain 0.027
Quieter than the analog horror setting: a hint of signal over the air that never covers the words.
5
Steady pace
0.97× speed, about −0.5 semitones
A barely noticeable slowdown that adds weight and gives each instruction room.

Stay between 40% and 60% for bulletins people must understand; save 80% and up for the moment the signal fails. The emergency alert voice generator makes speech only; the effect never adds an alert tone.

How it works

How to write and voice a fictional emergency alert

1
Invent the source
Name a town, an agency and a station that do not exist. Open with who is speaking and who the message is for.
2
Write plain instructions
Short commands: close, stay, do not. Put the one impossible instruction in the middle, worded like the others.
3
Voice it at 50% and export
In the emergency alert voice generator, nudge the slider until it sounds like radio but every word is clear, then download the WAV.

Horror films and shorts

The car radio, the TV left on in the next room, the bulletin that explains just enough.

Gloved hand holding up a two-way radio in a concrete stairwell under a fluorescent light

02

Survival and horror games

A safe-room radio that updates as the player progresses, or a looping message in an abandoned town.

Laptop with a bright blank screen on a dark desk, crumpled notes and a mug beside it

03

ARGs and online mysteries

A recovered bulletin on an in-world website, framed so players know it belongs to the game.

A hand turning the dial of a glowing vintage tube radio on an old wooden desk

04

Audio dramas and podcasts

A recurring station notice that ties episodes together. When the script changes, run the new version through the emergency alert voice generator.

Tips

Rules for fictional emergency alerts

Make it obviously fictional: invented places and agencies, inside a film, game or story that frames the broadcast.
Never play or post it where people could mistake it for a real alert: not on real radio, not in public spaces, not in group chats without context, never with a real agency’s name.
Listen once as a stranger would. If an instruction is unclear on first hearing, shorten it.
Repeat the key instruction. Real bulletins repeat, and the repeat is where the horror line hides best.
In an EAS scenario video, leave the attention tone out, or design an original sting that sounds nothing like a real alert signal.
