SUMMARY OF THE INVENTION A low-cost practical sound comparison learning device is created.
Means for Solving the Problems When a normal audio medium and an IC memory are combined and audio data is recorded once from the medium in the IC memory, "rewind, fast forward, reproduction, change of reproduction speed" is performed only by the IC memory. Function can be realized repeatedly. Reproduce your own voice with your own ears by playing the sample voice and your own voice in the IC memory as the textbook, and realize the comparison function with the voice of the sample as the textbook.
BEST MODE FOR CARRYING OUT THE INVENTION
When the sample sound (A) is reproduced by the sound source reproduction control (1), it is automatically recorded in the IC memory. That is, analog sound can be converted to digital and recorded in IC memory by sampling, I / O processing and compression processing.
-To reproduce digital audio data recorded in the memory, a reproduction signal is sent to the sound data access control, data is sequentially called from the data storage area SD (A) of the IC memory, and data restoration and I / O processing are performed. Via, can be played on the amplifier.
-Repetitive reproduction can be realized by IC memory without using mechanical media.
Similarly to the above procedure, the human voice (B) can be recorded and reproduced in the IC memory by the microphone (3).
When the data calling speed is changed by the speed control signal during the reproduction of the voice (A) or the voice (B), the reproduction speed can be freely changed. Even short voices that are difficult to hear can be heard at a reduced speed. In addition, the reproduction of audio data in the IC memory can be temporarily stopped (6) or a forward / backward search (9) can be performed at high speed.
According to the test results:
When reducing the speed, about 66% -83% of normal. Can hear and analyze voices in detail.
When increasing the speed, about 120% -150% of normal. Hearing training can be conducted.
-If a learning program is set up in advance, the learning function can be automatically realized. The flowchart of this program is presented in FIG.
・ It is difficult for humans to understand the accuracy of their pronunciation. If you do not record your voice on the media and compare it to the sample voice used as the textbook, you will not be able to understand your own shortcomings. The present invention solves the problem of human speech learning.
The sample voice (A) serving as a textbook is automatically recorded in the IC memory during reproduction. If there is a blank space in the sample sound (A) for a certain period of time, it is recognized as a break and the sound data SD (A) recorded in the IC memory is automatically reproduced several times. If a human voice is also blown into SD (B), SD (A) and SD (B) will be compared with SD (A) and SD (B) will be repeated several times. After that, the sound data is reset, and the reproduction of the sample sound (A) is continued.
[Example] Language education, voice education such as singing and pronunciation, training for people with hearing and pronunciation impairments.
The present invention is useful for language education, voice education such as singing and pronunciation, and training for those with impaired hearing and pronunciation.

Claims (4)

  1. ICメモリ中に一度音声データを記録した場合、ICメモリだけで「巻き戻し、早送り、再生、再生速度変更」の機能を繰返し実現できる。このため、これらの動作をモータなど機械的な要素から最大限に切り離しできる。テープなど音源メディアの走行消耗を最大限に抑え、高速な音声検索と機敏な再生を実現。When audio data is recorded once in the IC memory, the functions of “rewind, fast forward, play, change playback speed” can be realized repeatedly with the IC memory alone. For this reason, these operations can be maximally separated from mechanical elements such as a motor. It minimizes the running wear of sound source media such as tapes, and achieves high-speed voice search and agile playback.
  2. 自分の音声を自分の耳で再確認し、教本となるサンプルの音声と比較機能を実現。図1で示すように、テープ・CD・MD・MP3など学習サンプル音源からの音声AをICメモリに記録すること(▲1▼)により、メモリから繰返し再生ができる(▲4▼)。人の模倣音声BをICメモリに記録すること(▲3▼)より、ICメモリから人の声も繰返し再生できる(▲5▼)。音声Aに続きBと連続再生を繰り返すことにより、A・Bの比較ができる。この事は人に音声の模倣学習手段を提供できる。また、ICメモリに記録するため、人の学習音声を音源メディアへの録音動作は生じず、音源サンプルに書込むなどの影響はない。Reconfirm your own voice with your own ears, and realize the comparison function with the voice of the sample used as a textbook. As shown in FIG. 1, by recording a sound A from a learning sample sound source such as a tape, CD, MD, or MP3 in an IC memory (1), it can be repeatedly reproduced from the memory (4). By recording the imitation voice B of the person in the IC memory (3), the voice of the person can be repeatedly reproduced from the IC memory (5). By repeating the continuous reproduction with B following the sound A, A and B can be compared. This can provide humans with a means of learning imitation of speech. In addition, since the sound is recorded in the IC memory, the operation of recording the learning voice of the person on the sound source medium does not occur, and there is no influence of writing the sound to the sound source sample.
  3. ICメモリ中の音声データの呼出し速度を変えれば、音声の再生速度を変えることになる。音声学習トレーニングに効果的な再生速度の変更範囲を設定できる。
    ・速度を遅くする場合、約平常の66%−−83%。音声を細かく聞き取れ、分析できる。
    ・速度を速くする場合、約平常の120%−−150%。ヒアリングの強化訓練ができる。
    ICメモリに記録された音声データを上記の速度範囲で再生する場合、人の音声は歪みを最小限に抑えながら、きれいに聞き取れる。
    Changing the calling speed of the voice data in the IC memory changes the voice playback speed. It is possible to set a change range of the reproduction speed effective for the voice learning training.
    When the speed is reduced, it is about 66% -83% of normal. Can hear and analyze voices in detail.
    -When increasing the speed, about 120%--150% of normal. Hearing training can be conducted.
    When audio data recorded in an IC memory is reproduced in the above-mentioned speed range, human voice can be heard clearly while minimizing distortion.
  4. 音声学習プログラム:(図3を参照)
    教本となるサンプル音声(A)は再生時、ICメモリに自動的記録される。サンプル音声(A)に一定時間の空白があれば、区切りと認識し、ICメモリ中に記録されたサウンドデータSD(A)が自動的に数回再生。もしSD(B)に人の声も吹き込んだ場合、SD(A)に続きとSD(B)と連続再生を数回繰り返す、SD(A)とSD(B)の比較になる。その後、サウンドデータをリセットし、サンプル音声(A)の再生を継続。
    Voice learning program: (See Fig. 3)
    The sample voice (A) serving as a textbook is automatically recorded in the IC memory during reproduction. If there is a blank space in the sample sound (A) for a certain period of time, it is recognized as a break and the sound data SD (A) recorded in the IC memory is automatically reproduced several times. If a human voice is also blown into SD (B), SD (A) and SD (B) will be compared with SD (A) and SD (B) will be repeated several times. After that, the sound data is reset, and the reproduction of the sample sound (A) is continued.
