JPH0675522A - Self-pronunciation confirming device - Google Patents

Abstract

PURPOSE:To efficiently execute practice in pronunciation and pronunciation correction of a person having a speech disorder by providing a counter, which sets the time leg between the read and the write of a digital signal, and a microprocessor for reproducing. CONSTITUTION:The time lag from recording to reproduction is set to a time counter 5 by a setter 5a which 1 to 10sec as the unit. When a user starts speaking to a microphone 1 thereafter, electric oscillation is converted to a digital signal by the A/D converter 2a of a microprocessor 2 for recording and is stored in an IC memory 4 capable of random accessing. Then, a microprocessor 3 for reproducing makes access to the IC memory 4 in accordance with the set time lag, and the read signal is converted to analog electric oscillation by a D/A converter 3a, and a receiver 6 is operated, and he hears his pronunciation to confirm whether it is good or not. When recording reaches the end point of the IC memory 4, it is automatically returned to the starting point to continue the recording and reproduction.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-pronunciation confirming device used for pronunciation practice for foreign language acquisition and correction of pronunciation of a person with language impairment.

[0002]

2. Description of the Related Art Humans cannot objectively listen to their own voice at the same time as vocalization. That is, what is heard as one's own voice is a composite of three elements: direct interaction between the input and output areas of the cerebrum, vibrations transmitted through bones, and vibrations of air received by the ears. It can make a big difference from just listening.

Therefore, for example, it was not possible to practice pronunciation for learning a foreign language and correct pronunciation for a person with a speech disorder only by listening to the pronunciation of another person such as a teacher. Using a tape recorder, I could objectively hear my own pronunciation, but it was inconvenient to operate, and I was unable to hear my self-speaking continuously after a while. The present invention has been made in view of such circumstances, and objectively confirms the pronunciation of one's own, and always corrects the incorrect part while consciously correcting the pronunciation to improve the pronunciation of one's own efficiently in a short period of time. The objective is to be able to objectively listen to one's own statement in the official place and to immediately correct the pronunciation so as to help the understanding of the audience.

[0004]

A microphone 1 for converting its own voice into an electric vibration, a recording microprocessor 2 for A / D converting the electric vibration into a digital signal, and an IC memory 4 for writing the digital signal. This is a self-sounding confirmation device comprising a reproducing microprocessor 3 for reading out a digital signal from the memory 4 and performing D / A conversion, and a time counter 5 for setting a time lag for writing and reading in units of 1 to 10 seconds.

[0005]

Since the user's pronunciation can be heard with a time lag of 1 to 10 seconds, it is possible to practice pronunciation for learning a foreign language and correct pronunciation of a person with language impairment.

[0006]

An embodiment of the present invention will be described below with reference to the drawings. First, the time lag from recording to reproduction is designated to the time counter 5 by the setting device 5a in seconds. Then, when vocalization is started toward the microphone 1, this electric vibration is caused by the recording microprocessor 2 to the A / D converter 2
It is converted into a digital signal by a and written (stored) in the IC memory 4 which can be randomly accessed. Then, the reproducing microprocessor 3 accesses the IC memory 4 according to the designated time lag, and outputs the read signal to the D memory.
The / A converter 3a can convert a digital signal into an analog electric vibration, operate the receiver 6, and listen to the user's utterance to confirm the quality. Of course, when the recording reaches the end point of the IC memory 4, the recording / playback is automatically continued, returning to the start point.

The time counter 5 is a setter for setting the write and read address lengths. The above time lag is 1 second for short pronunciation practice and 5-10 for long pronunciation practice.
It is sufficient to set it to about a second. The above device is IC-sized and can be used by wearing it on spectacles (1 cm ³
The following volume) is configured.

[0008]

As described above, according to the present invention, at the time of recording / reproducing, recording / rewinding / recording like a conventional tape recorder is performed.
It does not require operations such as playback, and it can continuously play back immediately after a certain time that can be specified while recording continuously, so it is possible to practice pronunciation for foreign language acquisition and pronunciation correction for people with language impairment. Is what you can do.
