A voice input means for simultaneously inputting voices from a plurality of directions, a vibration generating means activated by rising of a voice input signal, a frequency discriminating means for discriminating a frequency component of the voice input signal, and visual information of discriminated results. The display means is provided for converting and displaying.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a voice detection device for the deaf and hard of hearing.

[0002]

[Prior art]

 Conventionally, this type of voice detection device is a device that informs the incoming call of a home or presence of a visitor by a lamp display, a device that displays audio information in a graph on an audio device, or converts voice into text information. There was something to display on the CRT.

[0003]

[Problems to be solved by the device]

 As described above, since the conventional voice detection device is a stationary type for a specific purpose in the home, it has a drawback that it cannot be carried and used for ensuring physical safety when the deaf person goes out. In addition, even at home, the detection method is confirmation only by visual inspection with a lamp, etc., so there is no recognition in the visual angle range of the deaf person and in a state where the eyes are closed, such as a nap / sleep state. It was difficult to recognize.

[0004]

[Means for Solving the Problems]

 The deafening vibration pager type voice detection device of the present invention detects a voice input means for simultaneously inputting and detecting voices from a plurality of directions, a vibration generating means activated by rising of the voice input signal, and a frequency component of the voice input signal. A portable vibration pager equipped with a frequency discriminating means for discriminating and a display means for converting the discriminated results into visual information and displaying the information. It can be recognized by the sensory vibration (tactile), display (visual), and vibration pattern of the voice detection device.

That is, the voice recognition method for the deaf person is switched from the conventional visual recognition method such as a lamp display to a method using a vibration / sensation means using a vibration motor, etc. It becomes possible to recognize the type of voice by the oscillation pattern of vibration and at the same time to obtain other auxiliary information by the visual information display method.

【Example】

 A block diagram of the detection device of the present invention is shown in FIG. The block diagram of FIG. 1 is divided into an information processing system and a power system. The information processing system includes a voice detection unit 1, an amplifier 2, a frequency discrimination circuit unit 3 (filters A, B, C), a logic unit 4, and a display 5. The power unit is composed of the vibration generating unit 6 that vibrates the outer case body largely. First, the signal input to the voice detection unit 1 in the information processing system is amplified by the amplifier 2 and discriminated into three kinds of band numbers by the filters A, B and C of the frequency discriminating circuit 3.

The three types of discriminated signals pass through the logic circuit 7 of the logic unit 4 to repeat the start and stop of vibration (A), (B), and (C). The sound pressure level for each band that has been discriminated is simultaneously displayed on the display 5, which is the visual information display unit, and the message / character information / voice level corresponding to the three patterns can be displayed. It is possible.

FIG. 2 shows an example of the structure of the vibration pager type voice detection device of the present invention. In FIG. 2, 1 is a voice detection unit (external microphone), 3 is a frequency discrimination circuit unit, 4 is a logic unit, 5 is a liquid crystal display for displaying visual information, 6 is a vibration generation unit using a vibration motor, Reference numeral 9 denotes an outer case body, and 10 denotes a battery power source for operating the above 3, 4, 5, and 6, respectively. The case main body 9 of this vibration pager type voice detection device is held at a position in contact with the body of the deaf person, and one voice detection unit 1 (external microphone) is separated from the case main body 9 of the vibration generation unit, and an extension cord is used. Optimal for voice detection We set it on the head (ear position) of the other person's body and performed voice detection.

First, a frequency discriminating circuit for discriminating a ringing tone of a telephone, which is a source of frequently used voice at home, into a ringing tone of a visitor, B, and other voices into C is incorporated. As a result of using the portable vibration pager with three types of vibration patterns (Fig. 3) as a mobile phone in normal daily life with the switching mode set to indoors, the difference between the ring tone of the phone, the ringer and the other voices was clearly identified. Compared with the conventional visual detection method that uses a lamp or the like that can be distinguished and detected, and requires constant attention, voice detection is more effective than the conventional method because a reliable initial recognition of sensory vibration can be obtained even in the unconscious state. It was also evaluated that it was easier to distinguish the voice type.

Next, regarding the use at the time of going out, a noise cut processing function is added to the circuit in consideration of the difference in the surrounding environment, for example, detection in traffic noise, etc., and a voice above a certain sound pressure level is detected. The outdoor switching mode that incorporates the frequency discrimination circuit is set. Furthermore, the external microphone input is divided into two directions, front and back, and a function to display the voice input direction on the display is added. Due to these functions (switching mode = outdoor), the signal sound to be detected in urban areas is limited to loud sounds such as emergency sirens of ambulances and horns of automobiles, but it is necessary for deaf people to detect in emergency situations. We were able to recognize the current degree of danger and the direction of voice generation, and we were able to obtain an evaluation that it was sufficiently effective as a portable aid for emergency detection of the deaf person.

[0011]

[Effect of device]

 As described above, by using the voice detection device according to the present invention as a portable device for the deaf person, it becomes possible to detect the presence or absence of voice, the direction of voice generation, and the detection of the characteristics of voice by the sensory vibration and the visual information. Therefore, it becomes possible to detect and recognize voice information that could not be easily detected when going out, such as voices from emergency sirens and loudspeakers, and horns of automobiles. Is effective for ensuring the safety of Further, the present invention is not limited to deaf and hearing impaired persons, and is also effective as a general assistant for group activities by adding a simultaneous calling function using a specific frequency oscillator as a vibration pager.
