7. The text input device as claim 6, wherein the associated character input dictionary stores the letter, the phonetic symbol, the separate word, the cipher, and the commonly used symbol.

8. The text input device as claim 6, wherein the associated character input algorithm generates a first sequence according to a use frequency of the at least a candidate from high to low.

9. The text input device as claim 8, wherein the speech recognition algorithm compares the at least a candidate with a pronunciation of the speech by the speech learning model according to the first sequence so as to generate a second sequence and pick up the term according thereto.

10. The text input device as claim 9, wherein the text input device further comprises a monitor coupled to the microprocessor and shows one selected from the group consisting of the code, the at least a candidate and the term.

11. The text input device as claim 10, wherein the monitor shows the at least a candidate according to the first sequence and the second sequence.

12. The text input device as claim 1, wherein the inputting device inputs at least one selected from the group consisting of a letter, a phonetic symbol, a plurality of commonly used symbols and a cipher.

13. The text input device as claim 12, wherein the phonetic symbol is one selected from the group consisting of a Chinese phonetic symbol, a Japan phonetic symbol and a Korean phonetic symbol.

14. The text input device as claim 1, wherein, when two codes from the inputting device are respectively inputted by two different input methods, the two codes are inputted directly through the inputting device according to the two different input methods without switching.

15. The text input device as claim 1, wherein the speech is a speech of the term pronounced by a user.
