Description

Specification

TECHNICAL FIELD The present invention relates to a voice information notification system and a voice information notification method.

The present invention relates to a voice information notification system for analyzing voice and a voice information notification method.

Background art

Conventionally, a voice information notification system has been devised to assist the behavior of a hearing-impaired person or a deaf elderly person. This conventional voice information notification system comprises a voice input unit having a data transmission function and a notification unit having a data reception function (both not shown). The surrounding sound is transmitted as it is as the sound data, and the notification unit receives the sound, turns on the lamp or generates vibration, and notifies the user that the sound has been generated.

However, in the conventional voice information notification system, when a voice is picked up, a lamp is turned on or a vibration is generated to notify the user, but the user knows that the voice is generated. However, it is impossible to know what kind of voice it is. For this reason, especially for hearing-impaired people and hearing-impaired elderly people, it is not possible to accurately grasp the situation when something happens around them, and to take the next action successfully There is a problem that can not be.

Disclosure of the invention

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Embodiment 1)

FIG. 1 is a block diagram showing a schematic configuration of a voice information notification system according to Embodiment 1 of the present invention.

The audio information notification system according to the present embodiment shown in FIG. 1 includes an audio transmitting device 1 that picks up a voice at a desired place and transmits it as an audio signal, and receives an audio signal transmitted from the audio transmitting device 1. And a voice analysis device 2 for analyzing O

The voice transmitting device 1 includes a microphone (hereinafter abbreviated as a microphone) 3 for inputting voice, a transmitting unit 4 for converting voice picked up by the microphone 3 into a radio signal and transmitting the radio signal, and a hollow radio signal. And a radiating antenna 5. The voice transmitting device 1 can be installed not only at the home of the user who uses the device, but also anywhere outside the home. And by installing it in various places even at home, you can pick up the sound at each place. '

On the other hand, as shown in the block diagram of FIG. 2, the voice analyzer 2 includes an antenna 6, a receiving unit 7 for demodulating a voice signal from a radio signal captured by the antenna 6, and a demodulation by the receiving unit 7. A voice analysis unit 8 that analyzes the waveform of the audio signal that was generated, a micro computer (hereafter abbreviated as “microcomputer”) 9 that uses various parts of the device, and a memory that stores various message data (for example, EEPR 0 M: Electrically Erasable PROM) 10, a time stamp unit 11 for recording time, a lamp 12 used to notify the surroundings that there was a voice response, and an analysis result by the voice analysis unit 8. The display unit 13 includes a display unit 13, a battery 14, a battery voltage detection unit 15, and a bus 16 for interconnecting various parts of the device.

The voice analysis unit 8 stores data for specifying various sound sources, and specifies a sound source by analyzing a waveform of a voice signal. For example, noise, car, motorcycle, train and airplane engine sounds, emergency vehicle siren sounds, level crossing siren sounds, signal signal sounds, rain sounds, thunder sounds, wind sounds, dog sounds, etc. There are nights of barking, birdsong, etc. In addition, if there is no data that corresponds to the data prepared in advance, information indicating that the sound cannot be identified is output.

The microcomputer 9 reads out the message data corresponding to the various analysis results of the voice analysis unit 8 from the memory 10 and displays the read message data and the time at which the voice was acquired on the display unit 13. The following is an example of the display.

• Time 0 0: 3 0 The following audio was recorded.

→ Click sound • Time 15: 20 The following audio was recorded.

"^ Car engine sound

Here, of the various messages stored in the memory 10, the emergency messages include emergency vehicles and level crossing sirens, and the visiting messages include the knocking sound and buzzer sound of people. , And the voice of a person. Environmental messages include weather and naturally occurring sounds, such as rain, thunder, and wind, and animal messages include sounds from animals and pets, such as dog barking. There are birdsong, etc.

The microcomputer 9 monitors the voltage of the battery 14 from the output of the battery voltage detection unit 15 in addition to the above functions. Do.

Next, the operation of the audio information notification system having the above configuration will be described.

When the sound is picked up, the sound transmitting device 1 converts the picked-up sound into a radio signal and transmits it. The wireless signal transmitted from the audio transmitting device 1 is received by the audio analyzing device 2, where the audio signal is demodulated, and then the waveform is analyzed. Then, the analyzed voice waveform is compared with the waveform data of various sound sources stored in advance, and the closest one is selected. After the closest one of the previously stored waveforms of various sound sources is selected, the time, place, and analysis result of the input voice are displayed on the display unit 13.

For example, if a knocking sound is picked up at 00:21, it is displayed as shown in FIG. “Time”, “Location”, “Waveform”, “Speech analysis result”, and “Speech volume” are displayed in this order. In the display example shown in this figure, at least two audio transmission devices 1 are installed, and one of the audio transmission devices 1 picks up the audio. 2 "

On the other hand, when there is no waveform close to the analyzed voice waveform, a message indicating that the voice cannot be determined (for example, “There is a voice that cannot be determined”) is displayed on the display unit 13. If an unknown voice is found, it is sent to the voice analyzer 2 as voice data It is also possible to record and register the type of audio.

Note that, when receiving the wireless signal from the voice transmitting device 1, the voice analyzing device 2 blinks the lamp 12 for a certain period of time to inform the user that the voice has been picked up. As described above, according to the audio information notification system according to the present embodiment, the audio transmission device 1 that picks up the surrounding audio and transmits the audio data, and the audio data transmitted from the audio transmission device 1 And a voice analysis device 2 for receiving and analyzing the result, and notifying the user of the result. The voice analysis device 2 displays the time, location, voice waveform, and analysis result of the voice input. Can see the changes in the environment at a glance. In other words, by displaying the waveform and loudness, it is possible to know how the sound is generated and the loudness of the sound.

Therefore, by using the audio information notification system according to the present embodiment, it is possible for even a person with hearing impairment or an elderly person who is far from the ear to know the change of the surrounding sound without worry, and an emergency may occur. However, the next action can be taken immediately.

In the above embodiment, the voice analyzer 2 is used alone, but may be incorporated in a mobile terminal such as a mobile phone or a PHS (Personal Handy-Phone System). In this way, even if a dangerous situation is encountered, emergency contact can be made by using the telephone function of the mobile terminal, and convenience can be expected to be improved.
