The app keeps the mic open all lesson. Pick a combination, tap Open mic.
Mic is closed.
Blue: mic level now. Red line: the app's "you are talking" line.
With the mic open, play each for ~10 seconds. Press the volume buttons, and pull down the notification shade. Tick what you see.
| Way | Music icon | Goes silent | No notification | |
|---|---|---|---|---|
| A audio element (the app now) | ||||
| B Web Audio | ||||
| C stream | ||||
| D audio element through Web Audio (would keep the speed control) |
With 1.5× ticked, play A and D: the pitch should sound the same as at normal speed, just faster. Tick if so: D sounds normal at 1.5×.
Tick a box only when it's true for that row. Try with different mic settings above if you like; the results note which settings were open.
Tap Start, then say one normal sentence at a normal voice ("Photosynthesis makes food from sunlight"), then stay completely quiet.
Each test tries four settings at once and reports each.
Quiet test: a voice-like sound plays for 20 s. Stay silent. It counts how often the app would wrongly think you interrupted.
Interrupt test: it plays; when the screen says SPEAK NOW, say something at a normal voice. It measures how fast it notices.
