If you are interested in measuring your CW copying accuracy in terms of speed (WPM) vs. signal-to-noise ratio (SNR)  please check out https://deepmorse.com/.

With the permission of ARRL/W1AW I have generated a set of noisy audio clips from ARRL code practice files ranging from 5 WPM to 40 WPM, and with SNR from 0 dB to -18 dB. See https://deepmorse.com/matrix.

After doing the test you can then plot your personal copying accuracy graph (accuracy vs. WPM vs SNR) as well as getting on the leaderboard https://deepmorse.com/lb/.

Any feedback, suggestions and ideas how to improve this site are welcome.

Mauri, thanks for the new files. I'm just getting started with them. Here's a suggestion for the next month. Make the files much shorter (1-2 minutes) by recording segments of the original broadcasts at different signal to noise ratios.
