What is interactive audio fiction? A plain explanation

Audio drama, plus a moment where the story turns to you and waits.

Interactive audio fiction is a story you listen to that pauses at certain moments, asks you something, and plays a different scene depending on your answer. It takes the voice and sound of an audio drama and the branching of a gamebook. You can try it in a minute: Last Train on Moonvale is free in full, in your browser, with no account.

The three parts

• A voice. Often one, talking to you directly. A cast is possible, but one voice makes it easier to believe the question is meant for you.
• A decision. The story stops or slows, and you answer. Depending on the work, you tap, speak, slide or type something.
• A consequence. The next scene is different because of what you did, and sooner or later so is the ending. Without this part, it is only a quiz in the middle of a podcast.

How it differs from its neighbours

• Audiobooks and audio drama: same pleasure in listening, but they go where they were always going.
• Interactive fiction on the page: the same branching, but you read it. The form has a long history, and it remains the richest source of ideas for the audio version.
• Voice games on smart speakers: you talk back, and it is usually built around puzzles and play rather than a story told to one person.
• Chat companions: you can say anything, but no one has written the story, so it rarely builds to anything or ends.

Why it is still rare

The honest reason is the cost of writing and recording. Every branch needs to be written well and voiced, so a seven-minute story can take far more than seven minutes of audio, and most of it is heard by only some listeners. That is also why the form works best at short lengths, where a few decisions can really change what happens, rather than at novel length, where branches have to fold back together.

What it is good for

It suits stories where your relationship with the speaker is the point. A question from someone you have been listening to lands differently from a menu on a screen. You feel a little caught out, and you care what he will think of your answer. That is why we build Moonvale around love stories for adults, intimate and never explicit: at a few moments he asks you something, you reply with a choice, a slider or a code, and each story has two to four endings.
