Some time ago I began recording dictation practice for my kids based on the 1st edition of the Gregg Notehand text. Even though the Notehand text is adamant about not using this particular edition for verbatim dictation, I do think it is useful to learn how to generate an outline on demand for practice, to test oneself; and indeed, in the introduction of the 2nd edition, it mentions that there were Text-Kits made for Notehand (how I would love to get my hands on those!) These mp3 recordings follow the 1st edition text very closely. If you have another edition of Notehand, consult this chart to find the equivalent lesson. I plan to record more in the future as time allows.
I’m lousy with numbers and dictating to a specific speed, but I believe all of these are under 50 wpm. Notehand was never meant to be speed-oriented, so I guess calculating the speed is irrelevant for this edition. Hopefully beginners will find this useful and non-intimidating.
