The invention relates to an input method of multi-language general multi-key co-striking type and a keyboard device, particularly suitable for inputting languages, such as Chinese, English, Japanese, Korean, German, Russian, and the like. On a basis of abiding by speech rules of various languages, the invention adopts the input method and the keyboard device, i.e. a multi-language general keyboard or a keyboard main body which is provided with mutually symmetrical fourteen keys or thirteen keys at the left side and the right side and the measure that a plurality of syllables (or necessarily singlehanded input consonants) can be realized once through singlehanded multi-key co-striking so that the keyboard input speed of various languages can catch up with the speech or thinking rhythm, and the aim that what you want and what you speak are what you get is realized. The physiological structures of the fingers are fully considered in the keyboard layout of the consonant/initial keys and vowel/final keys respectively at the left part and the right part so that co-striking is easy and natural without troubling users, the combinations of the consonants/initials and the vowels/finals resemble common voice symbol modes of various languages as far as possible, and the process of grasping the input method is easy and understandable, accords with a rule and can more rapidly and conveniently realize the aim that everyone can rapidly input.
