Sound quieter than this is ignored. Raise it (e.g. −40) if background noise shows up as dots; lower it if your voice isn't being picked up.

With the defaults (920 and 1270 Hz) an average man reads about 25% and an average woman about 75%. Changing these re-scores your saved history too, since the raw measurements are kept.
How to use it
Start listening and just talk. The big chart puts your resonance left→right and pitch bottom→top, just like Acoustic Genderspace. The bright dot is you right now, and the tail shows the last few seconds. The strip underneath shows both values over the last 30 seconds.
When you stop listening, the session is saved automatically (if you spoke for at least 5 seconds). Record clip saves a specific take that you can name, replay any time (the audio is kept), and compare later. Add audio file (or dragging files onto the window) analyses recordings you already have, like phone voice memos, mp3, wav or m4a. They're dated by when the file was last changed, which is usually when it was recorded. Everything shows up in Clips & Progress, with a chart of how your median pitch and resonance change over the weeks.
Listening to a video
Open the video in another tab of this browser, then press Listen to a tab. Pick that tab in the box that pops up and make sure Also share tab audio is switched on. Then play the video: the chart follows whoever is talking. Click Stop tab (or the browser's "Stop sharing" bar) when you're done. Record clip works here too. Tab clips save the pitch and resonance (not the video's sound), are labelled "tab", and aren't counted in your own progress.
Music, laughter and several people talking at once all get measured too, so the reading is clearest when one person is speaking over quiet background.
How resonance is measured
The website measures resonance against known words, which is why it needs set passages. This app works with any speech. It finds your formants (the resonant peaks of your vocal tract) many times a second and estimates how far apart they sit. Brighter, "smaller" resonance pushes them further apart. Averaged over a few seconds of speech this is a good guide, but the absolute number won't match the website's exactly. Use it to compare yourself with yourself.
Tips for consistent readings
- Use the same microphone and roughly the same distance each time.
- A quiet room helps. Fans and music can confuse the measurement.
- Whispering and very breathy voice have no pitch, so they won't plot.
- Compare clips of similar speech (e.g. the same paragraph, or the same kind of chat). Reading aloud and casual talking can differ.
