Morse Code Reference
Morse Code Translator with Audio
Convert any text to Morse code dots and dashes, or decode Morse code back to text. Listen to the audio playback of your Morse code.
Morse code was invented in the 1830s and is still used in aviation, amateur radio, and emergency signaling. Our translator supports the International Morse Code standard.
International Morse Code assigns a unique sequence of dots (short signals) and dashes (long signals) to each letter and number. A dot lasts one time unit, a dash lasts three units, and the gap between parts of a letter is one unit. Between letters, the gap is three units, and between words it is seven units. This timing structure makes Morse code unambiguous even without visual delimiters.
Morse code remains relevant in specific domains. Amateur radio operators use it (called CW mode) because it works at extremely low signal-to-noise ratios where voice communication fails. Aviation uses Morse code for VOR and NDB navigation beacon identification. It is also used as an assistive technology — Android and iOS support Morse code keyboard input for users with motor disabilities.
This translator handles the complete ITU International Morse Code character set: 26 Latin letters, 10 digits, and common punctuation marks. The audio playback feature uses Web Audio API to generate accurate dot-and-dash tones at a configurable speed, defaulting to 15 WPM (words per minute, where PARIS is the standard reference word).
How the Morse Code Translator Works
- Type text in the input field to convert it to Morse code
- Or paste Morse code (dots and dashes separated by spaces) to decode it
- Listen to the Morse code audio playback
- Copy the result or share it directly
Morse Code Basics
Morse code represents each letter and number as a unique sequence of dots (short signals) and dashes (long signals). SOS (... --- ...) is the most recognized Morse signal worldwide. Letters are separated by spaces and words by larger gaps. While rarely used in modern communication, Morse code remains relevant in amateur radio, aviation, and as an accessibility input method for people with limited mobility.
When to Use the Morse Code Translator
Use this tool when you need to convert text to Morse code for amateur radio communication, educational projects, or creative applications. It is also useful for decoding Morse code signals and for learning the Morse code alphabet through the audio playback feature.
Common Use Cases
- •Learning Morse code for amateur radio licensing exams
- •Creating Morse code messages for escape rooms, puzzles, or games
- •Decoding Morse code signals from radio transmissions or historical texts
- •Converting text to Morse code for jewelry, artwork, or personalized gifts
Expert Tips
- ✱Learn the most common letters first (E, T, A, I, N, S) — they have the shortest Morse patterns and appear most frequently.
- ✱Use the audio playback at slower speeds when learning, then gradually increase speed as you recognize patterns.
- ✱Practice decoding Morse by ear — it develops a different skill than reading dots and dashes visually.
Frequently Asked Questions
- SOS in Morse code is: ... --- ... (three dots, three dashes, three dots). It was chosen as the international distress signal in 1906 because the pattern is simple and unmistakable, not because it stands for 'Save Our Souls' — that's a backronym. You can type SOS into the translator above to hear the audio pattern and see the visual representation.
- Yes. Morse code has standardized patterns for all 26 Latin letters (A-Z), digits 0-9, and common punctuation marks including period (.-.-.-), comma (--..--), and question mark (..--..). However, it does not natively support accented characters, emoji, or non-Latin scripts like Chinese or Arabic. This translator handles the full ITU standard character set.
- Yes, though its use has narrowed. Amateur (ham) radio operators still use Morse code (called CW mode) because it works at very low signal strengths where voice fails. Aviation and maritime industries maintain Morse code proficiency as a backup. It's also used as an assistive technology — Android and iOS support Morse code input for users with motor disabilities who can tap but not type.
- Skilled operators typically communicate at 20-30 words per minute (WPM), with experts reaching 40+ WPM. A 'word' in Morse is standardized as 5 characters (the word PARIS). At 20 WPM, each dot lasts 60 milliseconds. The audio playback in this tool uses a standard 15 WPM speed, which is comfortable for learning and reading along.
