Measured voices · 2026-07-26

Famous voices, measured.

Every voice here went through the same instrument as every free reading on Resonate — the same six scores, on the same scale, with no adjustment for reputation. Each page shows the full acoustic readout, the recording it was measured from, and how to train the voice’s measured strength. The library is small and grows as we measure more.

Comparisons are based on Resonate's acoustic analysis of publicly available speeches. No endorsement or affiliation is implied.

Historic figures

Sourced from government, archival, and other public-domain recordings rather than a contemporary podcast or interview — kept separate because the sourcing and recording conditions are a different kind of thing entirely.

Think a measurement is wrong, or want a voice removed? Request a correction or takedown — we’ll re-measure it, correct it, or take the page down.
