Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device that emphasizes pronunciation that is unfamiliar to a learner who uses a speech material for learning a foreign language, that is, a pronunciation of a frequency that is difficult to hear.

[0002]

[Prior art]

 Those who want to learn a foreign language, especially Japanese people, often use textbooks, reference books, and other learning books to study. It is well known that when this method is adopted, it is possible to obtain relatively accurate knowledge about reading and writing. However, it is also well known that when relying only on the study book, it is not possible to accurately hear the pronunciation of the speaker, and therefore, it is impossible for the speaker to pronounce correctly. Therefore, in recent years, audio-based teaching materials such as tapes, records, and disks recording foreign languages, so-called audio teaching materials, have been used for hearing learning.

[0003]

[Problems to be solved by the device]

 However, in reality, even when such audio materials were used, it was often impossible to achieve the desired results. One of the reasons for this is that learners are less sensitive and therefore less audible to pronunciations that are unfamiliar or unfamiliar to learners, and as a result, similar to learning only with study books. However, it turns out that even when I pronounce it, I cannot reproduce this accurately. This is because, for example, in English conversation for a Japanese person, it is difficult to hear the sound of "th", and if it is vaguely heard, it may become a silent word, and it is recognized as silence. It means that there is also a chance.

[0004]

[The purpose of the device]

 Therefore, it is an object of the present invention to provide a device that emphasizes pronunciation that is unfamiliar to learners who use audio learning materials for foreign language learning, that is, pronunciation of frequencies that are difficult to hear. .

[0005]

[Means for Solving the Problems]

 The above object of the present invention is to provide one or two or more patterns that emphasize the pronunciation of frequencies that are difficult for a learner who uses an audio material for foreign language learning to learn according to the language to be learned. And a frequency characteristic changing device having a frequency characteristic pattern, and means for switching the frequency characteristic pattern.

[0006]

[Function of the device]

 According to the present invention, by emphasizing the pronunciation of a frequency of a foreign language that is difficult for the learner to hear, it can stimulate the learner's ears and allow the learner to grasp the features of the foreign language more quickly. .

【Example】

 Referring to FIG. 1, an amplifier according to the invention, generally designated by the reference numeral 1, ie, amplifier 1, is shown in a block diagram. The amplifier 1 is connected on the input side to a reproducing device 10 such as a cassette deck for various audio teaching materials such as cassette tapes, CDs and records, a CD player and a record player, and is connected to a speaker 20 on the output side. The amplifier 1 includes a preamplifier 2, and the preamplifier 2 includes a frequency characteristic changing device, that is, an equalizer 3. The equalizer 3 has frequency characteristic patterns I and II that are patterned so as to emphasize the frequencies of the language difficult for the learner to hear, depending on the learner and the language to be learned. A means for switching, that is, a switch for calling a desired frequency characteristic pattern is provided in the equalizer. Therefore, according to the amplifier of the present invention, the frequency characteristic pattern of the equalizer 3 can be switched according to the learner and the language to be learned. The preamplifier 2 is connected to the speaker 20 via the power amplifier 4.

In this embodiment, the above-mentioned various frequency characteristic patterns are set such that the learner is Japanese, and the pattern I is for English conversation. More specifically, the English conversation pattern I has a frequency characteristic as shown in FIG. 2 and emphasizes a band of 2 kHz to 12 kHz that is unfamiliar to Japanese, that is, hard to hear. Similarly, FIG. 3 shows a frequency characteristic of a pattern II for French conversation designed to emphasize the bands of 100 Hz to 300 Hz and 1 kHz to 2 kHz that are difficult for Japanese people to hear. Pattern III is a normal (flat) frequency characteristic. The electric signal having the frequency characteristic pattern of the selected equalizer 3 is amplified by the power amplifier 4 connected to the preamplifier 2 and supplied to the speaker 5 1 connected to the power amplifier 4. When using the amplifier 1 according to the present invention, an audio teaching material of a language to be learned, for example, a cassette tape containing an English conversation is set on the cassette deck which is the reproducing device 10, and the equalizer of the amplifier 1 connected to the reproducing device is set. The frequency characteristic pattern I for English conversation is selected as the frequency characteristic of No. 3. Then, from the speaker 5 connected to the amplifier 1, a band of 2 kHz to 12 kHz, which is a pronunciation of English conversation that is difficult for Japanese people to hear, is emphasized and flows.

The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the invention described in the claims for utility model registration, and these are also included in the scope of the invention. It goes without saying that it is included. For example, in the above embodiment, the frequency characteristic pattern is adjusted for Japanese, but it can be adjusted for other than Japanese, for example, Korean. In this case, since the Hangul language has a relatively small amount of voiced sound, the frequency characteristic pattern is adjusted so that the voiced sound is emphasized when learning a language of another country. Further, in the above embodiment, the equalizer 3 has two frequency characteristic patterns for learning called frequency characteristic patterns I and II, but it may have only one frequency characteristic pattern for learning. It may have one or more frequency characteristic patterns for learning. Further, although the equalizer is used as the frequency characteristic changing device in the above-mentioned embodiment, it is sufficient if a desired frequency characteristic pattern can be obtained, for example, a desired frequency characteristic pattern may be obtained by combining filters. .
