It's a mouth.
In your browser. Fully operational. You control it.
Pink Trombone is a real-time simulation of the human vocal tract, built by programmer and mathematician Neil Thapen. The pink blob on screen is a cross-section of a human mouth and throat — tongue, lips, velum, nasal cavity, the whole apparatus. Drag the tongue around and it changes position. Adjust the lip opening. Open or close the nasal passage. The simulation generates exactly the sound a human mouth would make in that configuration, in real time.
Linguistics researchers use this. Speech pathologists use this. People studying how humans produce sound use this to understand why moving the tongue 3mm to the left turns an "ah" into an "oh."
You will use it to make a sound like a sentient piece of meat trying to remember its own name.
That's fine. That's what it's for. Thapen built it open source, put it on the internet, and named it Pink Trombone, which is either the most clinical or most unhinged name for a vocal tract simulator, depending on how you look at it.
There is no goal. There is no score. You just move the tongue around and see what comes out.
You will be here for longer than you think.
