PURPOSE:To eliminate the need to use a speech waveform and enable voiceless or small-voice input by utilizing shape information on the lips and chin or shape variation as input information. CONSTITUTION:An information acquisition part 1 inputs the shape 11 of the lips and chin as two-dimensional image data through a CCD camera 12, etc. The obtained image data 13 are sampled at proper time intervals and the shape analytic part 21 of an information recognition part 2 analyzes the outlines of the lips and chin. Binary data 22 on only the extracted outlines of the lips and chin are inputted to the input cell of a neural network 23 after learning and a character string is obtained as an output 24. The character string obtained as the neural network output 24 is inputted to a language pressing part 31 as what is called a word processor, processes for document generation and storage, etc., are performed, and the result is displayed or printed as a document 32. |
