Please check the recording levels, and then start recording. [More detailed recording instructions here.]
Each slide shows a sequence number, followed a seven-digit telephone number. Please read the sequence number, pause briefly, and then read the phone number as in a fluent and natural way.
Also, read the digit '0' as "zero".
Thus if the 17th slide looked like this
(17) 629 - 4037
you would read it as
"Number seventeen. [pause.] Six two nine, four zero three seven."
You can advance to the next number by hitting the space bar. For other controls, click on "help?" (below left).
