Head Copy Machine

Experimental tool

This is an experimental tool and very much not finished. It may not work in all browsers.

Learn Morse code using just your ears and voice.

Speech Recognition

This trainer uses speech recognition to determine if you copied the character correctly. Press the button below to activate the microphone and then select a browser setting to authorise microphone use (if requested). The mic will then turn off again until required:

Choose the language you will be speaking in (including e.g. UK or USA):

Speech recognition language:

Please note that the speech recognition system may send the audio from your microphone to e.g. Google, Apple or Microsoft's servers for processing.

The recognition does not work in all browsers. It is known to work in Chrome (Windows/Android). In Chrome on mobile phones, there is an added bleep when the mic gets turned on or off.

Characters

You will be tested on the "Characters to practise". When you are doing well on those, the first in the "Next characters to learn" list will be added to the practice set. You can edit these lists yourself and/or set up the "Next characters to learn" using the character learning order from CW Academy, Koch, LCWO or LICW.
