BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a language hearing learning machine for training language hearing.

[0002]

2. Description of the Related Art To train a language hearing, practice using a language tape (video) and language text, or repeat with a repeat player using a CD (compact disc), a magnetic card or a cassette tape. I am doing hearing training while making it.

[0003]

[Problems to be solved by the invention] Practice using conventional language tapes (videos) and language texts, or C
D, magnetic cards, and cassette tapes are very difficult to hear in the training of language hearing while repeating with a repeat player, because the tempo of the original language is too fast for the Japanese to follow. On the other hand, if the original word with a fast tempo is slow-played by the repeat player, the whole is extended and becomes an unnatural original word.

Further, no matter how many times a long sentence is heard, what cannot be discerned cannot be heard, and even if an attempt is made to hear back a part that cannot be heard, the present machine has to repeat the same or perform slow reproduction. Furthermore, even if a person encounters a pronunciation word that is unfamiliar to Japanese, it is difficult to hear only one word repeatedly. Thus, a short sentence cannot be easily repeated in the hand.

Due to such a state, there is no teaching material at present which is suited to the individual learners' abilities and interests. Moreover, in modern language learning, it is not possible to keep pace with the progress of the learners and raise the level of the teaching materials. However, learning materials pre-adjusted for Japanese people are unnatural, and in many cases, they are actually useless.

Furthermore, if only the uncertain parts of the teaching material are put together, it is necessary to record on another cassette, and it is very troublesome to change the edited contents again.

[0007]

In view of the above circumstances, the present invention has made it possible to easily learn a language hearing that suits Japanese people. First, an MD player with a built-in RAM is used as a recording medium, and digitized language teaching materials are displayed on the liquid crystal display screen of the MD player. MD player records digital voice
An MD (mini disc) for reproduction is used. On the surface of the CD, micron grooves called "pits" are engraved,
Depending on the amount of light reflected, the presence / absence of the groove is converted into a digital signal and reproduced. The magneto-optical disk, which is the true character of "recording MD", is the magnetic "S
This is a method of substituting "pole" and "N pole". "S pole" means "with pit" and "N pole" means "without pit". The reason why magnetism is used is that it can be easily processed. Magnetism has a characteristic that "when it is heated to a certain temperature (= Curie temperature), the coercive force of the magnetic material is lost and it is easily affected by an external magnetic field." The MD recording principle utilizes this characteristic.

Next, using the voice processing software built in the MD player, the spaces between the words or phrases of the voice are provided visually. Record the words or phrases with a gap on the MD player and practice the hearing repeatedly. Repeat the editing so that it approaches the original sound as the learner progresses.

[0009]

In the present invention, the sound of the language used as the hearing teaching material is recorded in the MD player. The learner himself / herself adjusts the intervals of words and phrases, and the tempo of the whole, with a gap between the sounds recorded in the MD player.

The learner continues to make adjustments to an understandable level while listening to the processed voice. The phrase thus adjusted is recorded on the MD player and practiced repeatedly. As the listening ability improves, we will re-edit it so that it sounds closer to the native pronunciation. Also, it is easy to record the native voice of the field of interest of the learner and edit only the part for which the hearing training is desired.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail based on specific embodiments shown in the accompanying drawings. RAM (Rand shown in FIG.
The MD player (recorder) 1 that has om Access Memory (constant speed call storage device) built-in and displays audio data on it is used. A liquid crystal display screen 3 for displaying a waveform 2 of sound and an operation panel 4 are provided in front of the MD player 1, and a headphone 5 is provided.
Is detachably installed. Although an MD player will be described here as an example, a cartridge type HD (hard disk) / MO disk (magneto-optical disk) or the like that performs the same function as this may be used. Further, although the liquid crystal display screen 3 is described here as an example, a normal CRT / EL board / plasma display screen which performs the same function may be used.

First, as shown in FIG. 2A, the recorded English is displayed on the liquid crystal display screen 3 of the MD player 1 as the waveform 2 of the voice. Next, specify the playback range and listen to it. Make a guess of the inaudible part and repeat the part. The part that cannot be heard as it is is shown in Fig. 2B.
A space S, that is, a space is inserted as shown in FIG.

This is re-recorded on the MD player 1.
The re-recorded voice allows the learner to repeatedly listen and practice. Once the learner becomes accustomed to the practice and learns, it will be closer to the original sound. In this case, as shown in FIG. 2C,
Put the space S, that is, the space in only one place. Further, if the tempo is too fast, the phrase interval may be widened or the reproduction tempo of the part may be sent.

Further, as shown in FIG. 3A, the waveform 2 of the speech of the inaudible word is extracted as shown in FIG. 3B. Repeat and remember the word. Then listen to the entire phrase as shown in FIG. 3C. Also, for long sentences, make short sentences with unnecessary adjectives removed.

The phrase processed as above is MD
Record in the unrecorded part of player 1. And listen repeatedly until you can hear. If you still can't hear enough, adjust again and repeat. When the results of the training come out, re-edit the edited phrase so that it closely resembles the native one, and repeat the practice again.

[0016]

The present invention has a RAM having the above-mentioned configuration.
A language that displays audio information on a display screen on a player that has a built-in display screen that digitally displays audio data and an operation panel, and processes it with software while visually recognizing it so that even beginners can hear it. This is a hearing device, and since digital data can be expanded and processed on a liquid crystal display, it can be inserted at any position and at any length, making it easier for Japanese to hear foreign languages. Further, since the voice data is displayed in a waveform on the liquid crystal display screen of the MD player, the editing can be easily performed. Furthermore, it is possible to easily re-record the edited content with the MD player.

Further, according to the present invention, since the intervals between phrases can be extended without changing the reproduction tempo of each word, unnatural pronunciation is not produced. Furthermore, the present invention can connect only major parts of a long sentence, process it into a short sentence, and record it. After listening to this short sentence, you can grasp the meaning of the sentence, and then add and reprocess the abbreviated adjectives in order, and finally you will be able to hear the original long and complicated sentence.

Furthermore, according to the present invention, a favorite material can be recorded according to the ability and interest of each individual, so that the learner can select the subject himself or herself. For example, if you want to use a computer commentary, there may not be a commercially available language tape material that fits this purpose, but instead you should record the news in a video and select a computer related subject from it. If you record it on a disc and re-edit it on it, you can create learning materials exclusively for learners.

Further, according to the present invention, it is possible for the learner himself to process the voice for individual use until he is satisfied. Further, according to the present invention, since the voice waveform is displayed on the screen and the voice data is edited while visually observing the waveform, only the target portion can be easily selected. Also, by recording unknown words one after another, you can create a word book with a voice. Since the data is recorded in the MD player, it can be edited in alphabetical order.

Furthermore, according to the present invention, if the learning effect is improved, it is naturally possible to hear a sound close to the original sound. Even at that time, it is impossible to listen to the original sound suddenly, so if you edit the sound as close as possible to the original sound and repeat the practice, you will gradually improve. Further, the present invention can gradually get used to the particular tone of current affairs English by using, for example, bilingual news. You can get a sense of natural English, not unnatural English that makes it easier for Japanese to listen.

Further, the present invention provides an MD player and an RA.
Since editing is done using M, processing and recording / playback can be done smoothly. Furthermore, the present invention enables digital slow playback. To that extent, any speed can be set by software. This is not natural English, but it helps to understand the words that make up the sentence, understands what English is omitted, and once you understand the English sentence, you can not throw it. It becomes easier to recognize even in fast-paced English. Why is the present invention
Explain if it becomes easier to recognize even in fast-paced English.
As shown in FIG. 4, it is assumed that the length of the arrow in the figure indicates the length of time until the user recognizes and hears the word. Although there are individual differences and fluctuations due to words, these are indicated by arrows of uniform length for the sake of explanation. When the user recognizes the word in the waveform A portion, the voices in the waveform B and C portions are played before the user cannot hear the word, so that the B and C portions in the middle of the waveform A portion cannot be recognized. On the other hand, as shown in FIG. 4 (b), by reproducing by expanding the space S which is the interval (silent interval) between words, the speech from the waveform A'to the B'and C'parts and after is reproduced. Can be sequentially recognized. In addition, if the time required to recognize and hear a word is shortened due to the user's learning, and the arrow in the corresponding figure becomes shorter, the space between words inserted as shown in Fig. 4 (c) and Fig. 4 (d) The space (silence interval) of each is shortened sequentially (Fig. 4 (d)), or one space (silence interval) is deleted.
(Fig. 4 (c)) As a result, it becomes possible to gradually perform a hearing training of a sound that is close to natural. The operation to insert a space (silence interval) between words can be specified by the user by enlarging the waveform on the drawing as shown below. Therefore, a circuit and a program for grasping the hearing ability on the device side are unnecessary. To process the voice, the user performs an operation such as enlarged display including the front and rear of the waveform B section on the display unit and selecting a portion between the waveform A section and the B section. After that, the CPU processes the data on the RAM according to the program and records it in the MD section. In this way, the front and back voices including the processed waveforms A ′ and B ′ are reproduced to perform the hearing training. After training, shorten the interval (silence interval) depending on the degree of skill. Or listen to the original sound before processing and practice hearing with a more natural pronunciation. Next, software processing will be described. As shown in FIG. 5, the waveform B portion in the figure is a portion of a word that is difficult to hear. The range including the front and rear of the waveform B section is enlarged and displayed on the display screen. The user operates so as to select the waveform B section. The data on the RAM is processed so as to amplify the amplitude, for example, twice (FIG. 5 (b)). Hearing training is carried out by playing back and forth the audio including the processed waveform B part. Similarly, it is also possible to process the data on the RAM so that the waveform B part is a word part that is difficult to hear and only that part can be played back in slow motion (FIG. 5).
(d). In this case, the audio part before and after the waveform B part can be set to the normal reproduction speed. These are processes that are difficult to execute with a conventional hearing device using a tape or a CD-ROM. Further, as a development example of these, it is possible to carry out only a specific frequency band from the voice data by Fourier transform or the like, and perform noise amplification by amplifying or canceling it. Since it is a function that can be added very easily in, the detailed description will not be given.
