Announcer Voice Generator

An announcer tells the audience how big the room is

A scene set in a stadium and a scene set in a broom cupboard can contain exactly the same dialogue. What separates them is the acoustics and, far more reliably, a voice speaking to everybody at once. One tannoy line at the top of a scene does more world-building than a paragraph of description, because the listener has heard that kind of voice in a real building and knows immediately what sort of space they are standing in.

That is why an announcement is worth casting properly instead of treating it as set dressing. The announcer is not a character in your story, but they are a character in the scene: they have a job, a script they have read a thousand times, and an attitude towards both. The bored transit announcer and the delighted tournament announcer are doing the same work with opposite energy, and an audience reads the difference in about two seconds.

Three registers, three different casts

The arena register is loud, elongated and theatrical. Vowels stretch, the name lands last, and the pace drops at the moment of the announcement itself. There is a heavier variant of this — the trailer voice, three words per breath, all of them important — which works for ceremonial introductions and for anything you want the audience to take too seriously.

The transit register is the opposite. It is clear, even and faintly apologetic, built to be understood over noise rather than to be enjoyed. Transit announcements are dull on purpose, which means the comedy or the menace has to come from the content. A perfectly calm voice explaining that the station is closing because of something it declines to name is far more unsettling than any amount of growl.

The third register is in-world automation: the ship computer, the facility warning, the automated queue. This is the flat, unbothered one, and it is the register that most often carries plot, because an automated voice can say something appalling without reacting to it. It is also the easiest to overuse, so give it the two lines that matter and no more.

Writing an announcement that sounds like one

Real announcements have a shape: an attention phrase, the information, then a repetition of the essential part. "Attention, passengers. The nine-forty service to Halloway is delayed. The nine-forty to Halloway, delayed." That repetition is what makes it read as a genuine announcement rather than as a line of dialogue aimed at the audience, and it costs you six words.

Write each announcement on its own line so it becomes its own performance, and write pauses as sentence breaks rather than as stage directions. A parenthetical such as (over the PA) changes nothing about the render: a line that is entirely bracketed is skipped, and anything else is simply spoken. The PA feeling comes from casting plus your editor, never from a note in the script.

Numbers deserve a pass of their own. Platform numbers, gate letters, times and flight codes are exactly where a renderer's guess and your intention part company, and there is no pronunciation setting to correct it with. Generate the line, listen, and if "9:40" comes out wrong, respell it as "nine forty" and use that spelling everywhere in the script.

Where announcer scenes go wrong

The most common failure is length, and it is worth repeating because everybody does it once. An announcement that runs six lines stops being atmosphere and becomes an information delivery system. The audience starts listening to the announcement instead of to your characters, and you have handed your exposition to the one voice in the scene with no stake in the story.

The second failure is casting the announcer from the same band as your leads. A tannoy voice has to sound like it comes from somewhere else, and the simplest way to achieve that is to pick a voice that is nothing like anyone in the room — different pitch, different pace, completely different attitude. If two characters end up sharing a base voice because the project is crowded, make sure the announcer is not one of them.

The third is processing too early. Everything that makes a PA sound like a PA belongs to the mix, not to the render. Keep the source clean and you keep your options: the same take can be a pristine broadcast booth in one cut and a corroded speaker in a flooded corridor in the next.
