Phone audio lab

Work down the page in order. At the end, tap Copy results and paste them to Claude.

1. Microphone settings

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.

2. Ways of playing the tutor's voice

With the mic open, play each for ~10 seconds. Press the volume buttons, and pull down the notification shade. Tick what you see.

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.

3. How long until it notices you finished

Tap Start, then say one normal sentence at a normal voice ("Photosynthesis makes food from sunlight"), then stay completely quiet.

4. Talking over the tutor (mic open)

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.

5. Results
