The AI is the voice — never the author.
AeroVox modernizes the delivery of aviation weather without touching the data, the chain of authority, or the phraseology pilots already expect. Here's exactly what happens when you press play.
From observation to broadcast — in five steps
The single most important property: every spoken word is produced by deterministic rules operating on the authoritative observation — never improvised by a generative model. The voice is the only AI component. That is why it is safe to field.
Same data the official broadcast uses
AeroVox pulls the airport's live METAR — the standardized weather observation already produced by the existing ASOS/AWOS/AWS infrastructure. No new sensors, no parallel weather source, no second source of truth. If the FAA trusts the observation, AeroVox does too.

For the live flagships, AeroVox re-checks the observation on a polling cycle (default 30 minutes — matching the standard ATIS reissue cadence) and only re-voices a broadcast when the weather actually changes. Stable weather costs nothing.
Words come from rules, not from a model
The METAR is parsed into structured fields — wind direction and speed, visibility, sky layers, temperature/dewpoint, altimeter, weather phenomena — handling both U.S. format (statute miles / inHg) and international format (meters / hPa / CAVOK / TEMPO).
A fixed phraseology engine then assembles the broadcast script by rule, aligned to FAA Order JO 7110.65 conventions: aviation digits ("niner"), phonetic information letters, standard order, the data-group cadence pilots are trained to copy. The same observation always produces the same script.
Crucially, the engine refuses to invent. If a field is not in the observation, it doesn't appear in the broadcast. Every phrase is traceable to a specific field in the METAR — easy to audit, impossible to hallucinate.
Native, not translated
Each supported language has its own rule-based renderer — its own digit words, lexicon, cardinal-number grammar, unit conventions, and word order. Translation is never done by a model. The same parsed observation flows into separate native renderers for English, Spanish, French, Portuguese.
- EN — "Scattered clouds at two thousand two hundred"
- ES — "Nubes dispersas a dos mil doscientos pies"
- FR — "Nuages épars à deux mille deux cents pieds"
- PT — "Nuvens dispersas a dois mil e duzentos pés"
Adding a new language is a new renderer subclass, not a model retrain.
Human-quality voice, ATIS cadence
The finished script is voiced by a high-quality neural TTS engine, at a measured ATIS pace deliberately chosen so a pilot can copy the broadcast without missing data — the same staccato, group-by-group rhythm a controller uses on the radio. Information letters advance Alpha → Bravo → Charlie on each weather change, just like a real ATIS reissue.
The voice layer can be swapped — a different broadcaster voice, a per-language voice, or a customer's preferred voice — without touching the engine. The audio is the only piece a buyer ever hears change.
Side by side: a generative-AI broadcast vs. AeroVox
Asks a model to "describe the weather"
The model can hallucinate, paraphrase, drop fields, or invent phrases under stress. Two runs of the same input can produce different broadcasts. There is no defensible audit trail back to the original observation.
Renders broadcast text by rule
Words come from a deterministic engine reading authoritative weather data. Same observation in, same broadcast out, every time. Every phrase traces to a specific field. The voice cannot say something the data did not contain.
Designed to slot into existing operations
- No change to the data. AeroVox is downstream of ASOS/AWOS/SWIM — it modernizes how the existing observation is delivered, not what it says.
- No change to authority. The official observation and the official frequency assignment remain unchanged. AeroVox is the voice layer, not a chain-of-authority change.
- Phraseology-aligned. Output follows FAA Order JO 7110.65 / ICAO Annex 10 conventions per language.
- Auditable by design. Every broadcast has a deterministic mapping back to a METAR plus a timestamp — both replayable and certifiable.
- Software-defined. Deploys in days, scales instantly, improves with a configuration change rather than a hardware program.
- Dual-use. The same engine serves military expeditionary, civil non-towered fields, towered ATIS modernization, and international markets.
