What is Morse code?
Morse code is a method of transmitting text as sequences of short and long signals — dits (·) and dahs (—). Each letter and digit has a unique pattern. E is a single dit. T is a single dah. SOS — the international distress signal — is ··· ——— ···.
Developed in the 1830s and 40s by Samuel Morse and Alfred Vail, Morse code made near-instant long-distance communication possible over telegraph wires, and later by radio. It is still used today by amateur radio operators, in aviation navigation beacons, and as an assistive communication method.
Free Morse code translator
Teach Me Morse includes a free, two-way Morse code translator — open the Translate card above to use it. Type or paste English in the top box and the Morse equivalent appears live below; paste Morse (using · — / or . - /) in the bottom box and the decoded text appears above.
You can play the translated Morse as audio at standard 600 Hz timing, or download it as a .wav file to use in videos, songs, escape rooms, or radio practice. The translator supports the full ITU set: all 26 letters, 10 digits, and standard punctuation (. , ? ! ' / ( ) : ; - + = @ & " $).

How to learn fastest
Short, frequent sessions beat long cramming. Start in Learn mode — it uses spaced repetition to focus on letters you miss most. Once a couple of letters feel automatic, switch to Decode to train your ear. The Map mode shows the dichotomic Morse code tree so you can visualise how every letter is built from its parent pattern, and the Translate mode is handy for looking up a word fast or saving an audio clip.
Frequently asked questions
How long does it take to learn Morse code?
Most learners can recognise the full alphabet in two to four weeks with short daily sessions. Reaching a conversational speed of 15–20 words per minute typically takes several months of consistent practice. Teach Me Morse uses adaptive spaced repetition so the letters you miss appear more often.
What does SOS mean in Morse code?
SOS is the international distress signal, sent as ··· ——— ···. It was chosen in 1906 because the pattern is easy to recognise even through noise. It does not actually stand for “Save Our Souls” — the letters were picked purely because the signal is unambiguous.
What is the Morse code tree?
The Morse code tree (or dichotomic tree) is a binary diagram that helps you decode a Morse signal one symbol at a time. Start at the top; for each dit, take the left branch; for each dah, take the right. Wherever you end up is your letter. Open the Map mode above for an interactive version that lights up the path as you tap.
How does the Morse code translator work?
Open the Translate mode above. Type English in the top box and the Morse equivalent appears live below — or paste Morse (using · — / or . - /) in the bottom box and the decoded text appears above. Press Play to hear the Morse at standard 600 Hz timing, or Download .wav to save the audio. The translator supports the full ITU set: 26 letters, 10 digits, and standard punctuation.
Is Morse code still used today?
Yes. Amateur (ham) radio operators still use Morse code — often called CW, for continuous wave — because it cuts through noise at very low signal strengths. It is also used in aviation navigation beacons, by some military and emergency services, and as an assistive communication method for people with limited mobility.
