Start the hum cleanly. Hold it.
EBVP “coordinated onset”: the airflow and the vocal-fold closure arrive at the same time — no breathy /h/ leak, no glottal pop. We’ll play your speaking-center pitch, then you hum it on /m/ for 3 steady seconds.
Run the Speaking center lesson first — we tune the hum target to the pitch you naturally speak at.
