The Five Axes

A Speaker Signature is five numbers and nothing else. One article per axis: what feeds it, what it is not allowed to judge, and the point at which the number stops meaning anything.

1. Clarity: the axis with a formula

   The only axis where a published equation runs alongside the model rather than instead of it, and the only one your fellow members get no vote on at all.

2. Tonality: measured, then judged

   Your pitch is measured four times a second. The Tonality score is a judgement sitting on top of that measurement, and this article is about exactly where the handover happens.

3. Structure: the axis with no instrument

   The only axis with nothing acoustic behind it. Structure is read from what you said, by a model, against a four-part frame. In a Live Battle, buying yourself extra time costs you five points of it.

4. Energy: our weakest number

   The axis we would most like to be better. Energy comes from an uncalibrated microphone through a browser that is actively working against the measurement. It is useful within one recording and close to meaningless between two.

5. Intellect: counting the words you did not repeat

   The newest axis, and the only one with no human vote behind it. Half of it is a ratio anyone can compute from a transcript, and that half penalises one of the oldest devices in rhetoric.

6. Why pace is not an axis

   Words per minute is the most precisely measured thing in the system, and it is deliberately not one of the five scores. The reasoning behind that decision is the reasoning behind the whole method.
