Morse Code Translator
Text to Morse and back, with audio playback at any speed.
What it does. International Morse Code encodes letters as dots and dashes with strictly proportional timing: a dash is three dots long, the gap between symbols is one dot, between letters three, and between words seven. Getting the spacing right is what makes it readable — the timing carries as much information as the symbols.

How to use Morse Code Translator
- Type text to encode, or Morse to decode.
- Adjust the speed in words per minute and play it.
- Copy the result, or download the audio.
The timing is the hard part
Most people learn the alphabet and then find they still cannot read Morse, because the units of silence matter as much as the units of sound.
One dot is the base unit. A dash is three. The gap inside a letter is one, between letters three, and between words seven. Get those wrong and correct symbols become unreadable.
This is also why Morse is usually learned by sound rather than by memorising a table of dots and dashes. Experienced operators hear whole letters as rhythms, not as sequences to decode.
Why it survives
- It works at signal levels nothing else does. A human ear can pull Morse out of noise that defeats voice entirely.
- The equipment can be trivial. A switch and a transmitter is a complete station.
- It crosses languages. The alphabet is the alphabet.
- It works through any on-off channel — light, sound, tapping, a torch.
- It is still taught for emergencies, and SOS remains the internationally recognised distress signal.
Morse stopped being required for maritime distress in 1999 and for most amateur radio licences in the 2000s, but it has never actually gone away — it remains the most reliable mode available with the least equipment.
SOS is not an abbreviation
It does not stand for Save Our Souls or Save Our Ship. Those are backronyms invented afterwards.
SOS was chosen in 1906 because its Morse pattern — three dots, three dashes, three dots — is unmistakable, unbroken and impossible to confuse with anything else even in bad conditions. It is sent as one continuous symbol rather than three letters.
That is a small illustration of a general principle in Morse: the patterns that survived are the ones that stay distinguishable when the signal is poor.
Frequently asked questions
How do I read Morse code?
By rhythm rather than by symbol. Experienced operators hear whole letters as sounds, not as sequences of dots and dashes to decode. Learning from a printed table is the slowest route.
What is the correct spacing?
A dash is three dots long. The gap inside a letter is one dot, between letters three dots, and between words seven. The silences carry as much information as the tones.
Does SOS stand for anything?
No. Save Our Souls and Save Our Ship are later inventions. It was chosen in 1906 because three dots, three dashes, three dots is unmistakable in poor conditions, and it is sent as one continuous symbol.
Is Morse code still used?
Yes, in amateur radio, aviation navigation beacons and emergency signalling. It stopped being mandatory for maritime distress in 1999, but it remains the most reliable mode available with the least equipment.
What speed should I practise at?
Learn characters at 15–20 words per minute from the start, with long gaps between them. Learning slowly then speeding up teaches you to count dots, which is a habit that has to be unlearned.
