    摘要: A study system of a character recognizing and translating system is provided with a character data base for storing character data representing characters contained in a sensed image; a character shape analysis unit for analyzing the shape of a character to extract the features of character constituting elements constituting the character; and, a mask learning unit for generating sample mask data of the character constituting elements on the basis of the analysis result of the character shape analysis unit. A recognition system of the character recognizing and translating system is provided with a collating unit for collating the character data of a character to be recognized with the sample mask data so as to recognize the character.

    摘要: Frames making up an input speech are each collated with a string of phonemes representing speech candidates to be recognized, whereby evaluation values regarding the phonemes are computed. The frames are each compared with part of the phoneme string so as to reduce computations and memory capacity required in recognizing the input speech based on the evaluation values. That is, each frame is compared with a portion of the phoneme string to acquire an evaluation value for each phoneme. If the acquired evaluation value meets a predetermined condition, part of the phonemes to be collated with the next frame are changed. Illustratively, if the evaluation value for the phoneme heading a given portion of collated phonemes is smaller than the evaluation value of the phoneme which terminates that phoneme portion, then the head phoneme is replaced by the next phoneme. The new portion of phonemes obtained by the replacement is used for collation with the next frame.

    摘要翻译: 构成输入语音的帧各自与表示要识别的语音候选的一系列音素进行对照,由此计算关于音素的评估值。 每个帧都与音素串的一部分进行比较,以便减少基于评估值识别输入语音所需的计算和存储器容量。 也就是说,将每帧与音素串的一部分进行比较,以获得每个音素的评估值。 如果所获取的评估值满足预定条件,则与下一帧对照的一部分音素被改变。 说明性地,如果引导整理音素的给定部分的音素的评价值小于终止该音素部分的音素的评价值,则头音素被下一个音素代替。 通过替换获得的新部分音素被用于与下一帧进行核对。
