Experimental tool
This is a new tool and is not finished. It is meant to replace the ICR Trainer, Adaptive ICR and Adaptive ICR v2.
Hear a Morse character and answer it as fast as you can: type it, tap it, say it, or simply know it. The aim is Instant Character Recognition (ICR): knowing each character the moment it ends.
Choose how you answer, what you learn and how you progress, and press Play. Characters you find hard come up more often, and when you know your set the next character can be added.
What to learn
Choose which characters to practise and which order to learn them in:
Alphabetical, but not the best order for learning.
Select characters in the grid above by type:
Each CW Academy Beginner session introduces a few letters. Use the dark red buttons to select each session's letters.

How you answer
How you answer each character, and how it’s marked.
<SK> and <BK> have no key, so typing leaves them out. Type + for <AR> and = for <BT>.
Your spoken answer is sent to a speech recognition service on the internet. If it marks a right answer wrong, press Backspace or I was right.
Microphone
Allow access to your microphone. Check it works with the Volume Meter, or press Test Mic and say something. It works best without headphones, so that it hears the Morse as well as you.
How to practise
Define the practice steps by toggling the buttons below, and setting the delays.
Each character
On a hit
On a miss
Main path (continued)
Automatic progression
You know your set when:
- the newest character is right times out of its last , answered in under ms, and
- every other character is right at least times out of its last , answered in under ms.
Practise
Review
Every character, with what you answered beside it and how long you took.
Statistics
Each character’s Accuracy (how often you were right, as a percentage) and Time (the median time of your right answers, in milliseconds), and n, how many times it was marked. An arrow shows the change since your previous session or day. Pick a character to see how it has changed over time.
Practise a few characters and each will be summarised here.
Show as a table
The spread of your right answers’ times for each character, fastest first: the box is the middle half, the line in it the median. The dashed lines are 600 ms (instant recognition) and 2000 ms. A low median with occasional long stalls is not yet instant.
Answer a few characters with timing on (speak, type or tap) and their times will be shown here.
Show as a table
The characters you answered as another, most often first. Only answers the tool marked count: typed, tapped or recognised, and not overruled.
No confusions yet.
One point per practice session: how often you were right, the time of your right answers (median and middle half), and the character speed. They are shown together on purpose: raising the speed slows your answers for a while even as you improve.
Practise on more than one occasion and your progress will be charted here.

Help
Load some settings from a file (overwriting your current choices), or Save all the settings for this page in a file. Share Settings generates a link to bookmark your settings, insert into a document, or share with someone else. The Reset Settings button changes everything in this page to its default value.
Notes
Each way of answering and each course has a link of its own, such as /labs/ultimate-icr/?preset=phone,licw. They never set your speed.
Speech recognition sends your spoken answer to a cloud service. Indicating you were wrong by voice only listens for speech, on your own device.
Much of the learning method comes from Better-ICR, by John AJ1DM, by way of the Adaptive ICR Trainer.

Speech is not available in this browser
This browser has no speech synthesis, which is usual for a browser built into an app such as Facebook. The Morse still plays. To hear speech as well, open this page in your usual browser.
