Telekey

Learn to recognize Morse code by sound, one character at a time.

Telekey gives you focused listening practice with adjustable speed and clear, immediate feedback. Whether you’re starting out or sharpening your skills, choose your characters, listen to the signal, and enter what you hear.

PRACTICE AT YOUR PACE Set the character speed from 5 to 40 words per minute. Adjust Farnsworth spacing to give yourself more time between characters while keeping each signal’s rhythm intact.

CHOOSE YOUR CHALLENGE Practice letters A–Z, numbers, punctuation, and Swedish characters Å, Ä, and Ö. Start with a random 50-character exercise and choose the character groups you want to work on.

TWO WAYS TO TRAIN Let Telekey wait for each answer, or switch to continuous playback to practice keeping up with an ongoing sequence.

LEARN FROM EVERY ANSWER See correct answers and mistakes as you practice. Review your session’s accuracy, average response time, and statistics for individual characters to see what needs more attention.

TURN IMAGES INTO PRACTICE Take a photo or choose an image, extract its text, and review it before starting an exercise. Supported characters become a sequence for listening practice.

PRACTICE OFFLINE Training and image text recognition work on your device. No account is required.
