Description
METHOD AND APPARATUS FOR DISPLAYING WRITING AND UTTERANCE OF WORD SYMBOLS
Technical Field
The invention relates to a method and apparatus for use in teaching the association of spoken words with written words or objects.
Background Of The Invention
Numerous proposals have been made for using display screens to present words and phrases for viewing by students to assist in learning.
It is well known that children learn language progressively, which is to say that their acquisition of comprehended vocabulary, which may precede speech capability by more than a year, parallels their expanded circle of awareness and matches the realities they encounter within their circle of awareness. Hence, children first learn, in addition to "Mommy and Daddy", the body words, then the food words, then the bathroom/bedroom words, then on to the household words and thereafter the words pertaining to the larger environment such as the house yard, neighborhood, grocery store, shopping center and so forth.
A number of techniques have been used to teach language. For example, the presentation of a word at or near the head of the speaker in a tutorial setting on a video screen as the speaker spoke the word is old. More recently, U. S. Patent No. 5,741,136, issued in 1998, discloses a method of teaching using audiovisuals including the coordination of sight and sound.
There remains a need, however, for a method and apparatus for use in teaching the association of spoken words with written words or objects, and this is now provided by the present invention.
Summary Of The Invention
The present invention relates to an apparatus for presenting word symbols for a display as such symbols are uttered by a tutor comprising a device including a display screen; means for transmitting word symbols uttered by the tutor to the device; and means for displaying such word symbols on the display screen as uttered by the tutor. Thus, an observer observing the screen and hearing the utterances may associate the word symbols as seen and uttered. The device may also include means for displaying the image of the tutor on the screen, and is preferably a television set that includes the transmitting and displaying means.
If desired, the display may include only one word symbol at a time, with the word display being observed and heard by the observer-listener simultaneously. Also, the displaying means preferably displays the word symbols on the display screen near the mouth of the tutor so that the word may be associated with the lip movements of the tutor. The displaying means preferably displays the uttered word after a time delay, and can include means operable by the tutor for controlling the length of time of the delay. Also, the apparatus can further include headphones and a player unit which prompts the tutor as to words to utter, wherein homonyms are not included to avoid confusion.
The invention also relates to a method of teaching an observer to associate word sounds with written words which comprises providing a device that includes a display screen; transmitting word symbols uttered by the tutor to the device; and displaying the transmitted word symbols on the display screen as uttered by the tutor. Again, an observer observing the screen and hearing the utterances may associate the word symbols as seen and uttered. Advantageously, the image of the tutor is also displayed on the screen, with the image of the uttered word symbol preferably being superimposed upon the image of the tutor. As above, the word symbols are most preferably superimposed on the image of the tutor near the mouth of the tutor after a time delay from when the words are spoken by the tutor so that the observer may associate the word symbol with the lip movements of the tutor. If desired, the tutor can control the length of the delay of the displayed word symbols. Also, the tutor may be aided by headphones and a player unit which prompts the tutor as to which words to utter. Preferably, the tutor will be provided with a list of words which the tutor is instructed to deploy progressively in accordance with the observer's expanded circle of awareness.
Brief Description Of The Drawings
Preferred embodiments of the invention are shown in the appended drawing figures, wherein:
Fig. 1 is a view of a tutor and child viewing a television set providing video and word symbol presentations created by a auxiliary unit; and Fig. 2 is a view of a portable unit for enabling the tutor to provide word symbol presentations in response to word symbol utterances of the tutor.
Detailed Description Of The Preferred Embodiments
The present invention generally relates to an method, apparatus and system for presenting a word on a screen as a tutor utters or states the same word to afford the observer the opportunity to associate the spoken word with written word or words. The tutor's image
may also be displayed at the same time on the screen. Preferably, the tutor is a mother and the observer a young child from one day to two years of age.
The invention may include the following four elements, among others, all contained in a set-top box. The elements are a computer processing unit, a television camera, a microphone, and time-delayed, image control and voice-recognition software with character generating capability. The set-top-box may be plugged into the input portal of a conventional television set such that the mother or other tutor and child or other learner may be seated in front of the television set and see the screen. The camera is positioned so that the mother's image is displayed on the television set. It is a feature of the invention that when the mother or other tutor utters a word, the voice recognition software will recognize the word and cause it to be displayed on the television screen, via the character generator, preferably over the chin, beneath the lips, or at another appropriate location over the televised image of the mother or tutor. The positioning of the displayed text, generally below the mouth, is such that the viewer's eye is able to view the text and the lips forming the word at the same time.
For simplicity, the tutor will ordinarily utter one word at a time until the observer's vocabulary develops sufficiently. This can later progress to sort series of words or phrases as the observer's vocabulary increases. While preferably intended to be directed to child observers, the invention also can be utilized to teach vocabulary to older observers such as those individuals who are learning impaired.
It is an additional feature of the invention that an appropriate time delay occurs between the receipt of an image and sound by the camera and its presentation on the screen. This delay must minimally exceed the amount of time required to state an utterance such that the voice recognition software has time to establish that the utterance is completed and matches a word in the software's word inventory available for display. Typically, a delay of approximately one (1) second is suitable although the precise time is not critical. Of course, the delay should not be too long so that the child becomes distracted from viewing the screen nor so short as to leave the child focused on the living mother's origination of the utterance such that the child misses the echo performance on the screen. Upon recognition, the word is printed simultaneous to the slightly delayed playback of the image and sound so that the sounded word and the printed word appear at the same time. The printed word may precede the appearance of the sounded word by a short time, such as a fraction of a second, and may endure slightly beyond the completion of the sounded word. The effect of this presentation is that the television will appear to "echo' the tutor or mother with a slight delay; it is the echoed word on the television that will be simultaneously matched by the appearance of the display word near the image on the TV screen.
It is a further feature of the invention that the vocabulary or word inventory of the voice recognition software may be limited to the didactic purposes of a given or particular learning protocol or purpose. It is also an aspect of the invention that the voice recognition software not be suitable for narrative presentation but instead be limited to a one-word-at-a- time presentation of a specialized group of words. As the observer gains vocabulary, further versions of the software can provide groups of words or short phrases.
It is an aspect of the invention that, although generally intended for one-word-at-a- time use, it may be placed into a phrase mode such that a speaker may utter a short series of words or a phrase and cause it to be played back with the individual words appearing one at a time in simultaneity to the corresponding utterance. In this phrase mode, the words may be allowed to be retained on the screen and cumulatively build the written phrase from left to right, below the mouth of the speaker. In this mode, the system shall have access to a larger, conventional voice recognition software engine. Additionally, the delay feature would be user controllable such that the entire phrase may be completed before playback takes place.
It is an aspect of the invention that the word inventory include those words first encountered by the human being in life up to the first five thousand words. Preferably, the tutor/mother is instructed to deploy words progressively and in parallel to her child's own maturation over the months and expanded circle of awareness. A list of these words are included in the word vocabulary contained in the voice recognition software. The word vocabulary list should preferably contain progressive concepts in the following order: the common body words, common food words, the ordinary and ususal bathroom and bedroom words, the common household words and, finally, words pertaining to a larger environment. Of course, the tutor can offer any words in any order, as desired, although an instruction manual or audio cassette instruction tape can provide various suggested words or suggested word orderings, depending upon the needs of the observer.
It is an additional feature of the invention that the software will allow individual words to be added to the voice recognition vocabulary; desirable examples may include names of the family members and of the baby itself or of objects particular to the household in question. Generally, the voice recognition software inventory will not include homonyms which can create confusion since context sensitivity will not be available to the voice recognition software when single words or short phrases are used.
It is a feature of the invention that the voice recognition software may include code that enables the software to anticipate the order in which the words are likely to be uttered and presented to the software for conversion to printed presentation on the screen.
With respect to Fig. 1, the tutor (T) and observer-listener (O) are positioned adjacent a device 10 including a television set 12 and an auxiliary unit 14 positioned on and connected to the television set 12. Auxiliary unit 14 includes a camera 16 for capturing the image of the tutor (T) and transmitting it to set 12 for display on screen 13. Unit 14 also has an audio receiver 17, such as a microphone, for receiving utterances from tutor (T). The audio signal is converted to a visual display of letters, such as CAT, and are then displayed on screen 13.
Auxiliary unit 14 will include a central processing unit and voice recognition software and character generation software to create a signal for display on screen 13 faithful to the utterance of the tutor. The screen may alternatively be a computer monitor or other display device rather than a television.
In the operation of the embodiment of Fig. 1, the tutor (T) and observer (O), a child or other student, is positioned in front of set 12 and unit 14. The image (I) of tutor (T) and alternating the tutor (T) and the observer (O) are displayed on screen 13. When the tutor speaks a word, such as CAT, shown at 11, the word is also displayed 15 on the screen preferably close to the tutor's mouth so that the observer can readily associate the word with the tutor's lips and other facial movements. The most preferred location for presenting the displayed word is over the tutor's chin but below the lips, but other locations can be used as desired. The skilled artisan can routinely determine the optimum location for presenting the words on the display based on the observer. The software can provide for adjustability in the precise positioning of the words on the display.
The speaking or uttering of the word is simultaneous to the viewing in all cases. The viewing, however, may not always be simultaneous to the speaking inasmuch as the viewing may slightly anticipate the arrival of the audio and may endure beyond it slightly in one-word-at-a-time mode. In phrase mode where a phrase is accumulated, such as by scrolling it out, left to right, then the viewing of an individual word will endure beyond the corresponding utterance. It is preferred that the speaking always be simultaneous to a viewing of the corresponding word so that the observer can view the lips and mouth of the tutor. The utterance of one word at a time is preferred for optimum learning, but groups of words may also be spoken and thereafter displayed at the same time. The tutor (T) utters the word or words that he or she intends the observer-listener (O) to learn.
Turning to the embodiment of Fig. 2, a tutor (T,) is shown with a portable unit 20 having around his or her neck (n) using a flexible neck support 21. Unit 20 includes an audio receiver 23, a processor (not shown) and a display screen 26. In the operation of unit 20, an observer (O,) is positioned to view screen 26. When tutor (T,) speaks the word CAT, it is received, processed and displayed on screen 26 by unit
20 so that observer (O,) sees the word CAT simultaneously as he or she hears the word. Groups of words may be displayed and heard by the observer (O,).
To assist tutor (T) in presenting the words, instruction sheets or manuals may be used stating the words to be uttered for each age and stage of development of the observer (learner). Such instructions are particularly helpful for young children i.e., those that are one (1) to three (3) years old.
As an alternative, tutor (T) may use headphones (30) and a recorder-player unit (31) which instructs and prompts tutor (T) what words to utter for a series of tutorial sessions. Headphones (30) permit a person who is illiterate or lacks familiarity with the language to perform his or her task as tutor (T).
A word symbol may be a word, a part of a word, or a picture or symbol representing or suggesting a word or part of a word. For example, a picture of a cat, the letters GM the lettering "ing" are word symbols.
It is a feature of the invention that a manual may be included which gives the tutor guidelines in which words to use, how often, and in what order.
It is a further aspect of the invention that a personal audio cassette player, with headphones, is provided such that an illiterate tutor may correctly choose the words for utterance in the appropriate order and such that use of the invention will have the effect of not only teaching the student/child to recognize written words but also the illiterate tutor. It is an additional feature of the invention that where words refer to commonly available objects, the tutor may present in hand the appropriate object such that it is in the field of view of the camera at the time of the utterance such that quadra-partite association may be offered among the written word, the spoken word, the lip formation, and the contextual referent. It is also a feature of the invention that the word vocabulary available to the voice recognition software be progressive in nature and that the software be loosely context sensitive to the progression such that the software may anticipate but not require a certain order of progression through the vocabulary inventory.
It is a further feature of the invention that the time delay between the completion of the utterance of any given word by the mother or tutor and its repetition by the delayed response "live" television image of the mother or tutor be sufficient to allow the voice recognition software to note the completion of an utterance and that the delay endure long enough to allow for assurance that the child's attention is directed to the TN and not to the live mother. It is a further aspect of the invention that an adjustment tool will be made available to the mother or tutor such that she may adjust the time delay to particular needs or response tendencies of a specific child.
EXAMPLE A mother, with her baby in her lap, is seated in front of a television equipped with the inventive set-top box which is placed on top of the TV set. The mother is holding a baby bottle of milk in one hand near her cheek. She is looking at the camera lens of the set top box as instructed by either the manual or the audio cassette. She pronounces the word milk. Thereafter she immediately attracts the baby's attention in the direction of the TV. Two seconds later her image on the TV, holding the baby bottle, pronounces the word milk and simultaneously the word milk appears in large print over her chin, but not obscuring the lips, of the mother's image on the TV. The printed word milk hangs on the screen for V_ second after the utterance of the word milk, and then disappears. The mother's "live" image continues to appear on the screen allowing for the two second delay programmed into the set top box. This delay is adjustable by the mother from a minimum of approximately one (1) second (or that minimum time sufficient to complete the utterance of the longest word in the vocabulary inventory) to as much as five (5) seconds or that time required to reorient the baby's attention to the TV from possible diversion to the mother herself during the initial utterance.
