摘要： PROBLEM TO BE SOLVED: To reduce the storage capacity of a work memory into which a dictionary is loaded. SOLUTION: When recognizing the voice being inputted through a voice input section (23) by comparing the voice with a dictionary being loaded into a work memory (a RAM272), a voice recognition section (132) is provided to recognize a first word corresponding to the information displayed on a display section (21) as a silent model and uttering of the first word is eliminated to improve the degree of freedom in sounding. Moreover, when inputted voice does not correspond to the information being displayed on the section 21, the dictionary is changed by a dictionary control section to reduce the size of one dictionary and the storage capacity of the work memory to which the dictionary is to be loaded.

摘要： PROBLEM TO BE SOLVED: To improve the recognizing performance of the whole system by estimating the recognizing performance in a state wherein the contents of a dictionary are modified and previously deciding whether or not estimated modification is accompanied by deterioration in the performance of the system. SOLUTION: A user inputs modification contents of the dictionary such as a word to be added and a word to substitute. A recognizing performance decision part 104 estimates how the recognizing performance of the whole system changes when the modification that the user has inputted is actually done. A conversion candidate generation part 106 regards the modification contents that the user has specified as a candidate word or generates a candidate similar to the modification contents that the user has specified according to the decision result and outputs it on condition that set end reference is satisfied. When the user approves the output, a dictionary update pad 108 updates the contents of the word dictionary 112. Further, a dictionary update hypothesis generation part 110 generates hypotheses for the removal of an arbitrary word from the word dictionary 112 at all times.

摘要： PURPOSE:To obtain a character generating device which is suitable to power consumption reduction of a system and LSI-implementation by composing the device of plural modules and stopping the functions of modules which do not operate in accordance with modes. CONSTITUTION:A module 1 (13) is a vector block and a module 2 (14) is a raster block. For example, when mode information written in a mode register 11 indicates a mode wherein the process of the vector block is not performed for outline font data inputted to the character generating device, a block supply control circuit 12 does not supply a clock CLK1 to the vector block. A necessary irreducible clock, however, is supplied for transfer from a font input FIFO to an FIFO through the vector block. A mode wherein the process of the raster block is not performed is the same. Thus, the functions of the modules 13 and 14 which do not operate to perform conversion specified by the modes are stopped.

摘要： PURPOSE:To apply it to the output engines of various address allocation by coordinate-transforming according to the address allocation of the output engine. CONSTITUTION:A coordinate transformation circuit 203 has two kinds of the coordinate transformation methods of an LP use and a TTP use for applying to any one side or to both sides of a case when the output engine is a laser printer(LP) and a case when the output engine is a thermal transfer printer(TTP). That is, the coordinate transformation circuit 203 decides a value set to a coordinate transformation mode register 211 and coordinate-transforms by using a coordinate transformation parameter imparted from a CPU since there is a case in which coordinate-transforming for the LP is executed when the setting value is '0' and stores it in an FIFO-A204. Further, the circuit 203 coordinate-transforms by using the coordinate transformation parameter similarly since there is a case coordinate-transforming for the TTP is executed when the value set to the coordinate transformation mode register 211 is not '0' and stores it in the FIFO-A204.

摘要： PROBLEM TO BE SOLVED: To actualize an excellent speech recognition interface by limiting words and documents as objects of speech recognition and performing the speech recognition. SOLUTION: A speech analysis part 106 performs a noise process and takes a speech analysis of a speech inputted through a microphone 106. A speech recognition part 107 collates the input speech with the speech analytic result of the input speech calculated by the speech analysis part 106 by using a dictionary 105 and a sound model 108 in sequence to calculate the closest word in the dictionary 105. In this case, a dictionary switching part 103 selects one of dictionaries or switches them for the speech recognition according to the contents of dictionary switching information 102. For example, plural dictionaries are stored on a memory card or in a ROM 104, and when the speech recognition is performed, only a necessary dictionary is transferred to a RAM 105 to perform a speech recognizing process. Namely, words and documents to be recognized are limited and the speech recognition is performed.
