how to sync reading and listening (strictly SRS protocol)

You need a strict sync protocol. Step one is isolating audio to 1.25x speed. Step two is auto-generating transcripts to dump into your SRS database. Step three is running the audio while reviewing those exact SRS cards at 4-minute intervals. If you don't align the visual and auditory input down to the millisecond you are wasting neural plasticity. Do this for 90 minutes daily without exception.
