Abstract

In the case of letters of the alphabet such as "M and N" and "B and P", which are difficult to distinguish, recording of words consisting of a sequence of letters of the alphabet is effected in a word dictionary in a condition in which, in accordance with alphabetic input system information that is specified for each user, one of these letters of the alphabet is repeated twice, with the addition of "dot" before the letter in question. For example, the device is arranged to record in associated fashion the characteristic quantities of the time sequence corresponding to the word "PAM" and "dot PP dot A dot M". When the user performs voice input "PAM", this can be effected by uttering "dot PP dot A dot M", in accordance with the alphabetic input system information of the user in question. Voice recognition of this voice data is performed using the word dictionary corresponding to this alphabetic input system information of the user in question.

Description

technical field [0001] The invention relates to a voice recognition device. Background technique [0002] For those engaged in logistics, medical work, etc., there is a desire to realize work efficiency and hands-free work through voice recognition. [0003] In particular, in logistics, medical work, etc., it is often necessary to input a character string of mixed letters and numbers such as the model number and ID of the product. The sound recognition accuracy of letters and numbers is good and there are few false recognitions. It has made a great contribution to the efficiency. [0004] However, letters, in particular, have very short sounds and many characters whose sounds are close to each other, making it difficult to recognize them correctly. [0005] For example, most of the parts with strong utterance energy such as "C", "E", and "T" are parts extended to the final sound "イー" ([i:]), which are difficult for humans to hear. [0006] In particular, in noisy environm...
