工具介绍
摩尔斯电码并不神秘,它只是一套把字母换成点和划的对照表;难的是手写容易错位,一个空格没打对就整句看不懂。 Morse code is not mysterious — it is a table swapping letters for dots and dashes. What is error-prone is writing it by hand: one wrong space and the whole line becomes unreadable.
这里输入文本就直接出电码,粘回一段电码也能读成文字,还能按你设的速度把节奏播出来听,判断自己敲得对不对。 Type text and the code appears; paste code and it reads back as words; and you can hear the rhythm at your chosen speed to check whether your own timing is right.

常见问题
为什么中文变成问号?Why do Chinese characters become question marks?
摩尔斯电码只有拉丁字母、数字和少数标点,没有汉字码位;要传中文得先转成拼音或电报码。Morse only covers Latin letters, digits and a few punctuation marks; Chinese needs pinyin or a telegraph code first.
词和词之间靠什么分?How are words separated?
用斜杠 / 分隔单词,字母之间用空格;解码时三个以上空格也当词间隔。Words use a slash, letters use spaces; when decoding, three or more spaces also count as a word gap.
播放速度怎么理解?What does the speed mean?
WPM 是每分钟单词数,按 PARIS 标准换算成一个点的时长 1200/WPM 毫秒,15 WPM 时一个点约 80 毫秒。WPM is words per minute; the PARIS standard gives a dot length of 1200/WPM ms, so 15 WPM is about 80 ms per dot.
为什么会听到嘀嗒而不是语音?Why do I hear beeps instead of speech?
本工具播放的是真实电码节奏(用 Web Audio 合成 600Hz 正弦波),方便练抄收与校对。It plays the actual rhythm, synthesized as a 600 Hz tone with Web Audio, which suits copying practice and checking.
