an open research benchmark

Do AI voice agents hear how you feel?

Say "fine, whatever, just book it" cheerfully — book it. Say it in a defeated sigh — a good agent checks first. Same words, different right answer.

Take a dozen calls: can you out-hear the AI?

hears

models can often name the caller's tone when asked

acts?

whether hearing it changes what they do, versus reading a transcript

you?

every game session is an anonymous data point in the human baseline

How the benchmark works

  1. Every test item is one caller line, heard in two deliveries with identical words — so only the voice can change the right action.
  2. Models (and you) hear a clip and choose from the same action menu: proceed, confirm first, ask a question, escalate to a human…
  3. Controls keep it honest: every model also gets a transcript-only twin of each call, and a words-only speech-to-text pipeline sets the floor for what the voice adds.
  4. Everything is open source — items, audio, scoring, and (soon) a harness to test your own voice agent against the same calls.
