Because you're too smart for slow, Fake-Sounding AI

Runs on brain-melting math you’ll never have to touch. Built for devs who ship, not just talk.

Actually understands you in real time, no awkward pauses, no blank stares

It doesn’t just keep up, it dominates. Complex addresses? Weird phone numbers? Random acronyms no one should be saying out loud? All handled without flinching. You talk, it listens, and responds like it actually paid attention.

Sandbox mode

Break things without consequences. Test keys render every voice and bill nothing.

Webhooks That Actually Work

We ping your server the second something happens: speech started, finished, interrupted, interpretive dance.

Blink-and-you'll-miss-it speed

Flabbergasted responds faster than you can regret your last input.

Doesn't butcher your address

From “4B Elm St.” to international phone numbers, it nails the details like it's been stalking your mailbox.

Clones your voice so well it’s borderline unsettling

We’re talking high-fidelity, freakishly accurate voice cloning that sounds like you (or whoever you want) down to the weird little inflections.

Normal

The original voice: clean, clear, and disturbingly accurate.

Chipmunk

A helium-fueled voice that sounds like it just inhaled a balloon.

Deep

Sounds like it belongs in a movie trailer. Gritty, bold, and over it.

Talk goes in. Magic comes out

Powered by a brainy, low-latency model stack we built so you don’t have to Google what “state space” means

Fully Private (like, actually)

Your data stays locked down. Nothing leaks, nothing leaves. Not even for “just a little training.

Brainwaves in a Box

Real-time, on-device intelligence without the PhD. We did the hard math so your app doesn’t have to.

Get startedRead the docs

Memory? Minimal.

Big brains, tiny footprints. Runs like a champ even on devices with commitment issues.

One Model. Many Minions.

Spin up a whole army of apps using a single model. No sweat, no slowdown.

Zero Lag. Zero Excuses.

Streams in real time. Blinks slower than it responds.

Goldfish? Not Here.

Remembers the long stuff, perfect for apps that think past their next sentence.

Battery-Friendly Brilliance.

Smarter doesn't have to mean hungrier. Runs lean, even on the go.

Memory That Sticks.

Remembers what happened last time, across sessions, devices, and your existential crises.

Ten lines from text to voice

Install the SDK, pick a voice and start streaming. The first sentence plays while the rest is still being written.

Get an API keyRead the docs

speak.ts

Node

import { Flabbergasted } from "@flabbergasted/sdk";

const client = new Flabbergasted({ apiKey: process.env.FLAB_KEY });

const stream = await client.speech.stream({
  voice: "freja",
  text: "Your table for two is booked for eight tonight.",
  format: "mp3",
});

for await (const chunk of stream) {
  player.write(chunk);
}

One endpoint

Text in, audio out. Batch for files, streaming for conversations, same request either way.

Streaming by default

Audio arrives over WebSockets in chunks, so playback starts before the sentence is done.

SDKs you already know

Typed clients for Node and Python, plus plain HTTP for everything else.

FAQ yourself

Real questions. Real answers. No marketing fluff.

Contact sales
Is there a limit to how much audio I can generate?
If you're on the free plan, yes, we’re generous, but not reckless. Paid plans scale from ‘fun side project’ to ‘we accidentally launched a startup.’
Can I clone my voice?
Yes, and it's freakishly good. You’ll wonder if you recorded it yourself or if we hired your evil twin.
How fast is the real-time voice response?
Fast enough to feel psychic. We’re talking sub-blink latency: no buffering, no weird pauses, just instant talkback.
Can I use this in production apps?
Please do. We built this for real builders, not demo decks. Production-safe, scalable, and not held together with duct tape.
What audio formats do you support?
MP3, WAV, and whatever else your audio nerd heart desires, depending on your plan. No DRM traps, just clean sound.
Do you support multiple voices or languages?
Yes to both. Clone your voice, swap in others, or go multilingual. Your app doesn’t have to speak just one language, so why should you?
Can I integrate this with my stack?
Easily. Use our API, set up webhooks, and wire it into whatever tech mess you’re running. No judgment.
What happens if I hit my usage limit?
We don’t shut you down mid-sentence. You’ll get a heads-up before anything breaks. Then you can upgrade like a grown-up.

Our customers

Don’t take our word for it. Here’s what the people paying us think.

OstrelOstrel

"Patients stopped waiting on hold at night. The voice sounds calm, asks the right questions and hands off to a nurse when it should."

BrinvikBrinvik

"Drivers talk to it like a colleague on the radio. Our dispatchers finally get status updates without chasing anyone."

LumaroLumaro

"Our learners practice speaking every day now, not just once a week with a tutor. The voices are patient, funny and never judge an accent."

Read Lumaro's case study

KestlyKestly

"Freezing a lost card used to take a ten minute queue. Now it takes one sentence, and customers thank the voice before they hang up."

ValdraValdra

"It runs right on the thermostat, no cloud round trip. People say it is the first smart home voice that actually feels quick."

SorvikSorvik

"Our characters finally answer the player instead of reading lines. Every playthrough sounds different, and testers keep talking to them for fun."
