Abstract

PURPOSE:To preclude a malfunction due to speech recognition by inputting an article name, etc., by voice and reading data corresponding to the voice- inputted article name out of a PLU (price look-up memory) according to the recognition result of a coincidence means when accessing the PLU through a speed recognizing circuit. CONSTITUTION:The article name is voided in front of a microphone 7. For example, when 'thigh of beef for SHABSHAB (paper-thin sliced meat)' is voiced, the speed recognizing circuit 8 recognizes its contents and the coincidence means selects speech data 'thigh of beef for SHABSHAB' in a speech dictionary 9. Then a PLU calling means reads data 'thigh of beef for SHABSHAB' out of the PLU 6. Therefore, the whole of a long article name need not be voiced and the probability of malfunction in speech recognition can be decreased.

Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electronic price scale equipped with a PLU (Price Look Up Memory) in which data such as product name and unit price are preset for each product number. It is.

2. Description of the Related Art A conventional electronic fare scale of this type is constructed as shown in FIG. In other words, the CPU which controls the entire system has a ROM2 in which programs are set and an RA in which data is stored.
A scale 4 is connected to M3 and further weighs the weight of the product.
A keyboard 5 is connected to a PLU 6 in which data such as product name and unit price are set in advance for each product number.

In such an electronic price scale, the product is called up from the PLU 6 by using the keyboard 5 and inputting the product call code.

Problems to be Solved by the Invention A PLU call using a call code cannot be performed unless the operator has memorized the call code. For this reason, a comparison table of call codes and product names is provided, but since the number of products is extremely large, searching for the desired product name from the comparison table is a difficult task. Moreover, the environment in which electronic fare scales are used often involves the use of water, and there is also the problem that the comparison table becomes wet with water and becomes difficult to read.

Means for Solving the Problems A voice recognition circuit, a voice dictionary storing voice data including shortened nicknames or nicknames in addition to the original name of the product name, and voice signals from the voice recognition circuit and information in the voice dictionary. A matching means for making a match with audio data, and a PLU calling means for calling the PLU by making a one-to-one correspondence between the recognition result by the matching means and the PLO are provided.

A correspondence is established between the contents set in the action PLU and the contents stored in the voice dictionary, and a voice recognition circuit inputs a PLIJ call using a voice such as a product name, and the input voice signal is sent to the voice dictionary by a matching means. The system searches for voice data from within the PLU, and based on the recognition result by the matching means, the PLU calling means calls up the data corresponding to the product name entered by voice from the PLU, especially when the product name is long. There is no need to say the whole thing out loud,
This can reduce the probability of occurrence of voice recognition malfunctions.

Embodiment An embodiment of the present invention will be explained based on FIGS. 1 and 2. Components that are the same as those described with reference to FIG. 3 are designated by the same reference numerals, and description thereof will be omitted. First, a voice recognition circuit 8 is connected to the microphone 7. A speech dictionary 9 is connected to this speech recognition circuit 8 . This voice dictionary 9 is PL
It is connected to the PLO 6 and stores voice data similar to the product name data stored in the PLO 6.

This audio data is, for example, "for beef momosukaki"
``For beef thigh shabu-shabu'' ``For beef parasu kaki''
The content is "for beef loin yakiniku" etc.

In addition, the product name [J for beef momosukyaki] is long, so
It is also remembered that the original name ``Gyu Mosukiyaki J'' was shortened from the original name ``Gyu Mosuki Yaki J.'' Similarly, the product name ``Beef Momo Shabu Shabu'' was abbreviated from the original name ``Gyu Momo Shiyabu.'' I also remember the nickname.

Although not shown, matching means is provided between the speech dictionary 9 and the speech recognition circuit 8 to match the speech signal from the speech recognition circuit 8 with the speech data in the speech dictionary 9. , a PLU calling means is provided between the speech dictionary 9 and the PLU 6 for calling the contents of the PLO 6 based on the recognition result by the matching means.

Next, the dictionary table 9 is provided with a table l l lJ< for comparing the product name storage section 10 provided therein with the number of the PLU 6.

In such a configuration, the product name is pronounced into the microphone 7. For example, when you say "for beef thigh shabu-shabu", the voice recognition circuit 8 recognizes the content, and the matching means selects the voice data "beef thigh shabu-shabu" in the voice dictionary 9, and based on the recognition result, PLU
The data for "beef thigh shabu-shabu" is called from the PLO 6 by the calling means. Therefore, even if the operator does not know the code number of the product, the operator can call up the PLU simply by saying the name of the product, and there is no need for a reference table or the like.

Then, even if you do not pronounce it as ``J for beef momo shabu-shabu'' but pronounce it as ``beef mosuki-yaki'' or ``beef moss-yaki'', it is set so that it corresponds to ``1'' of PL and U according to table 11. Therefore, the state is the same as when it was manually made [for beef thigh shabu-shabu].

Effects of the Invention As described above, the present invention includes a voice recognition circuit, a voice dictionary storing voice data including shortened nicknames or nicknames in addition to the original name of the product, and a voice signal from the voice recognition circuit and the voice. a matching means for matching audio data in the dictionary;
Since the recognition result by the matching means is configured with a PLU calling means that calls the PLU by making a one-to-one correspondence with the PLU, the contents set in the PLU and the contents stored in the voice dictionary are made to correspond. A voice recognition circuit inputs a PLU call using a voice such as a product name, the input voice signal is searched as voice data from a voice dictionary by a matching means, and the PLU is called by a PLU calling means based on the recognition result by the matching means. The data corresponding to the product name entered by voice can be called up from within the system, which eliminates the need for the operator to memorize the product number or prepare a comparison table. For long product names, the product name can be called out manually using voice data that includes shortened nicknames or nicknames in addition to the original name. This greatly reduces the probability of speech recognition malfunctions caused by the speech recognition circuit. This has the effect of making it possible to
