Abstract

The utility model relates to an electronic dictionary which applies optical character recognition and speech recognition to inquire words. The electronic dictionary comprises an image collecting device electrically connected with a microprocessor, which is used to carry out image collection to words from environment, to process the images, and to transfer image signals after preprocessing to the microprocessor, a speech input device electrically connected with the microprocessor, which is used to collect sound data from the environment and transfer the sound data to the microprocessor, the microprocessor which is used to obtain pre-processed images or speech data from the environment, to carry out image text message recognition or speech data and command information recognition, then, to carry out dictionary data information inquiry and processing according to recognized text information and command information, to store results, and to display the results on a display screen, a memorizer electrically connected with the microprocessor, which is used to store dictionary data supporting inquiry, images and sound data, the text information and control commands after image recognition and sound recognition, and a switching key electrically connected with the microprocessor.

Description

The smart electronics dictionary

Technical field

The utility model relates to the electronic dictionary that word enquiring is carried out in a kind of applied optics character recognition and speech recognition.

Background technology

Electronic dictionary Related product in the market divides from input mode can be divided into two classes: the electronic dictionary of keyboard input, the 2nd, the electronic dictionary function that the infrared scan input equipment is subsidiary.

See also shown in Figure 1ly, the electronic dictionary of known keyboard input adopts imitative PC design, uses keyboard input and control.So owing to use the keyboard volume too to dwindle, simply dwindle the inconvenience that keyboard can bring the user to use, this just makes traditional electronic dictionary can not accomplish that " pocket " is not easy to carry.

The inquiry of dictionary generally has two kinds of situations, and the one, for reading the interprets queries of carrying out smoothly, another kind is to finish to write work is write (spelling) to word, speech inquiry.The conditional electronic dictionary aspect these two, all needs the user to operate step by step with keyboard, and process is loaded down with trivial details.

See also shown in Figure 2, though how the incidental electronic dictionary function of known scanning product and does not know to have the unmatched advantage that reads with the foreign language (as Arabic) of keyboard input for some because the reason of scanning input uses more directly, convenient than conditional electronic dictionary.But it has just possessed the interprets queries function of easy-to-read, word, speech is write the query function of (spelling) and but can't be realized.

The utility model content

The purpose of this utility model is to overcome above-mentioned weak point of the prior art, provide a kind of by using Optical Character Recognition system, speech recognition system to come various written languages are imported and controlled, the cancellation keyboard, reduce number of keys, make that it is smaller and more exquisite, fashion, portable smart electronics dictionary to dwindle machine volume.

The purpose of this utility model can reach by following measure:

This smart electronics dictionary comprises microprocessor, storer and display screen, and its special character is: described smart electronics dictionary also comprises:

Image capture device is electrically connected with microprocessor, carries out image acquisition from outer bound pair literal, then image is handled, and pretreated picture signal is sent in the microprocessor;

Voice-input device is electrically connected with microprocessor, gathers voice data from the external world, and this voice data is sent in the microprocessor;

Microprocessor comprises: optical character identification module, voice messaging identification module, dictionary enquiry module; The optical character identification module is carried out image text information Recognition, storage, demonstration to the image that obtains pre-service from the outside; The voice messaging identification module carries out speech text and command information identification to the speech data that obtains from the outside, and afterwards, to text message identification, storage, demonstration, command information is carried out; The dictionary enquiry module, according to phonetic order to text message edit, browse, query manipulation, and store, be presented at its execution result on the display screen;

Storer is electrically connected with microprocessor, is used to store dictionary data, image and voice data, the text message after the image recognition, the text message after the voice recognition and the steering order of supporting inquiry;

The switch switch is electrically connected with microprocessor.

The purpose of this utility model can also reach by following measure:

Described image capture device adopts the OCR recognizer.

The utility model has following advantage compared to existing technology:

1, to compare traditional dictionary more direct, simple and direct for the phonetic entry process of optical imagery, has the advantage that can import various written languages.

2, compare with scanning product incidental electronic dictionary function, the utility model product function is perfect, speech voice input function can realize portablely that also word, speech write the inquiry of (spelling).

3, obtain information from the external world simply, directly, saved the loaded down with trivial details of manual input.

4, because optical imagery and speech input device have replaced keyboard, saved some peripheral circuits, therefore, that electronic dictionary can design is smaller and more exquisite, fashion, be easy to carry.

Embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

See also Fig. 3, shown in Figure 4, described smart electronics dictionary comprises:

Adopt the image capture device 2 of OCR recognizer, be electrically connected with microprocessor (MCU) 1, carry out image acquisition, the data message that identifies through OCR from outer bound pair literal, it is carried out corresponding response, operation, and pretreated picture signal is sent in the microprocessor (MCU) 1;

The speech data that collects via extraneous microphone 31 is sent to the voice-input device 3 that is electrically connected with microprocessor (MCU) 1, and this speech data is sent in the microprocessor (MCU) 1.Because existing computer speech identification aspect discrimination is low, can adopt identification at 26 English alphabets, 10 numerals and some control commands, adopt the method for fuzzy matching, again by in a large number, repeatedly voice check and correction brings up to discrimination more than 90%.

Microprocessor (MCU) 1 comprises: optical character identification module 11, voice messaging identification module 12; For from external image collecting device 2, as pick-up lens, obtain the image of pre-service, carry out the image text information Recognition, and carry out the dictinary information inquiry and handle, and store, be presented at its result on the display screen according to the text message that identifies; For the speech data that obtains from external voice input equipment 3, carry out the identification of speech text and command information, and carry out the dictinary information inquiry and handle, and its result is stored, is presented on the display screen 5 according to text message that identifies and command information;

With the storer 4 that microprocessor (MCU) 1 is electrically connected, be used to store dictionary data, image and voice data, the text message after the image recognition, the text message after the voice recognition and the steering order of supporting inquiry; With the switch switch 6 that microprocessor (MCU) 1 is electrically connected, be used to control start, the shutdown of smart electronics dictionary.Steering order comprises key command and phonetic order.

Method of operating:

Control by switch switch 6 or voice 31,, inquire about according to steering order then, at last explicit user Query Information on display screen 5 by phonetic entry (letter, numeral) or literal picture identification extraction text message to scanning, taking pictures.

The above only is preferred embodiment of the present utility model, and all equalizations of being done according to the utility model claim scope change and modify, and all should belong to the covering scope of the utility model claim.
