Abstract

PURPOSE:To easily and positively input and inform a scheduled event and a scheduled time by providing an amplifier circuit, an A/D converter, an audio recognizing unit, a controlling unit, a signal compressing unit, a time dictionary memory, a voice synthesizing unit, a human body detecting device, a timer circuit etc. CONSTITUTION:When a person who desires to be notified of a scheduled plan is to register the time of the schedule, a time voice is passed through the side of a change-over switch 14 indicated by a solid line, processed by an audio recognizing unit 4, and the recognizing pattern is written in a memory unit 6 in accordance with an instruction from a controlling unit 5. Then, when the scheduled event is to be registered, an audio indicating the scheduled event is passed through the side of the switch shown by a broken line. The digitalized event voice is coded through, e.g., PCM or the like to be converted to a parameter in a signal compressing unit 9, so that the signal is compressed. A memory 11 stores the compressed signal. The controlling unit 5 always compares the scheduled time registered in the memory unit 6 with the time indicated by a timer circuit 7. When the time of the circuit 7 passes the schedule time, the schedule time and corresponding scheduled events are erased.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an audio notification device that provides audio notification of nine daily scheduled events and their times.

(Prior art) Conventionally, this type of alarm device memorizes scheduled events and their scheduled times by inputting characters using a keyboard and encoding them. This was to be notified by an alarm such as a buzzer.

(Problem to be solved by the invention) However, with conventional devices, inputting/outputting scheduled events and scheduled times and operating methods are complicated because characters are entered using a keyboard, etc., and users often forget to set the settings to be notified by alarms. (There was an issue of not being notified of scheduled events and scheduled times.)

The present invention solves the above problems by providing scheduled notification.

The object of the present invention is to provide a device that allows easy and reliable input and notification of scheduled events and scheduled times.

(Means for Solving the Problems) In order to solve the above problems, an audio alarm based on the present invention includes an amplifier circuit that amplifies an audio signal corresponding to a scheduled time input via a microphone, and an A/D converter that converts the digitalized audio signal into a digital signal; a speech recognition unit that recognizes the audio digitized by the A/D converter; a control unit that processes various signals; and the speech recognition unit. a storage unit that registers time information recognized by the controller according to instructions from the control unit; a signal compression unit that compresses a digital audio signal announcing a scheduled event that is similarly input via the microphone; A schedule memory in which compressed schedule information is registered, a time dictionary memory in which the time information is registered in advance, and the time information registered in this time dictionary memory and the schedule information registered in this schedule memory. It consists of a voice synthesis section that synthesizes the voices of both, a human body detection device that detects the presence of a person, and a clock circuit that stores the time when the human body is detected by this detection device via the control section. Only when the input time is before the input scheduled time, when the human body is detected, a voice command signal is input from the control unit to the speech synthesis unit to determine the time corresponding to the input scheduled time. Both the time information registered in the dictionary memory and the schedule information registered in the schedule memory corresponding to the input schedule time,
Each of these is converted into synthesized speech and output sequentially. Further, the present invention provides for transmitting both the time information and the schedule information at any time between the input schedule time and the time after the input schedule time determined by the control unit. It is also possible to provide an audio notification device that sequentially outputs synthesized voices.

(Function) In the audio alarm system according to the present invention, those who require scheduled notification input both the scheduled time and the scheduled event via a microphone, and the presence of a person is detected by the human body detection device. Only when the time is before the input scheduled time, both the input scheduled time and the corresponding scheduled event are announced by voice.

Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an audio notification device showing one embodiment of the present invention. The audio waveform input through the microphone 1 is converted into an electrical signal, amplified by the amplifier circuit 2, and converted into a digital signal by the A/D converter 3. The subsequent changeover switch 14 is used to switch between the scheduled time/scheduled event registration mode.It is set to the solid line side when registering scheduled time audio, and to the broken line side when registering scheduled event audio.

Next, referring to FIG. 1, the operation of the audio alarm based on the present invention will be explained.

When a party who requires schedule notification registers the schedule time,
The time voice passes through the solid line side of the changeover switch 14, is subjected to voice recognition processing by the voice recognition section 4, and the recognition pattern is written into the storage section 6 according to an instruction from the control section 5. Subsequently, when registering a scheduled event, the scheduled event audio passes through the dotted line side of the changeover switch 14. The signal compression unit 9 encodes the digitized scheduled event audio using PCM, ADPCM, or the like, and converts the audio into so-called PARCOR.

Each signal is compressed by converting it into a parameter representing a characteristic such as LSP, and is written into the schedule memory 11.

For example, I plan to go to the ward office at 9:00 am on February 20, 1989 to get my resident card. ”, first register “ichi”, “kyu”, “hachi”, “kyu”, “zero”, “
``Two''``Two''``Zero''``Zero''``Kyuu'', followed by ``I'm going to the ward office to get my resident card.''

” by voice input.

The control unit 5 constantly compares the scheduled time registered in the storage unit 6 with the time of the clock circuit 7, and when the time of the clock circuit 7 passes the scheduled time, the scheduled time and the corresponding time are compared. Scheduled events will be deleted. If necessary, the data may be left as past data for a while. 8 is a human body detection device, in which a light emitting part and a light receiving part of an infrared sensor are installed in a place where notification of a scheduled event and scheduled time is required, and a person blocks infrared rays between the light emitting part and the light receiving part. Examples include a device that detects the presence of a person, and a device that detects the presence of a person by detecting far infrared rays emitted from the human body. Only when there is a scheduled time registered in the storage unit 6 at the time of the scheduled time, the control unit 5 instructs the controller 5 to store the time information in the time dictionary memory 12 corresponding to the scheduled time and then the schedule corresponding to the scheduled time. Both the scheduled event and the scheduled event in the memory 11 are converted into synthesized speech by the speech synthesis section 10 and outputted by the speaker 13.

In addition, if it is necessary to notify both the scheduled time and the corresponding scheduled event after the scheduled time, when registering the scheduled time, register the scheduled time for the time after the scheduled time. For example, enter voice input in the same way as when
Schedule r February 20, 1989 09:00, 1989 02
At 3:00 p.m. on the 20th of the month, go to the ward office to get your resident card.<,'' is input by voice. The control unit 5 constantly compares the time after the scheduled time registered in the storage unit 6 with the time of the clock circuit 7, and when the time of the clock circuit 7 passes the time after the scheduled time, The scheduled time, the time after the scheduled time, and the corresponding scheduled events are deleted.

FIG. 2 shows the voice input procedure for registering scheduled times and scheduled events.

First, when starting registration (step 200), switch 1
4 as shown by the solid line in FIG. Step 201: Enter the scheduled time via microphone 1.
), the speech recognition unit 4 performs recognition processing, and it is determined in step 202 whether or not the scheduled time has been correctly recognized.

If the determination is NO and the scheduled time is not recognized correctly, the process returns to step 201 and the scheduled time is input again. On the other hand, the judgment is Y
At the time of ES, the scheduled time is registered in the storage unit 6.

Next, set the selector switch 14 as shown by the broken line in FIG. 1, and input the scheduled event corresponding to the scheduled time via the microphone 1 (step 203).
The signal is compressed by the signal compression unit 9 and written to the schedule memory 11. In step 204, it is determined whether or not the registration is completed. If the determination is NO, the process returns to step 201 and the scheduled time and scheduled event are input in the same way as in the above procedure. On the other hand, if the determination is YES, the registration is completed. (Step 2
05).

FIG. 3 is a flowchart showing the scheduled output of synthesized speech when the presence of a person is detected.

In the reproduction mode (step 300), it is always determined whether there is a person present (step 301). When the determination is YES, the human body detection time is stored in the time circuit 7 shown in FIG. 1 (step 302>,
In x step 303, it is determined whether the scheduled time is registered and the human body detection time is before the scheduled time. If the determination is NO, the process advances to step 307 and the playback mode is ended, and if the determination is YES, the synthesized voices of both the scheduled time and the scheduled event corresponding thereto are sequentially output (step 304). In step 305, it is determined whether or not there is a schedule other than the scheduled time when the output has finished, under the same conditions as in step 303.

When the determination is No, the process advances to step 307 and the playback mode is ended, and when it is YES, the process advances to step 3 (16). In step 306, the presence of a person is detected as in step 301, and when the determination is NO, the process proceeds to step 3. Proceed to step 307 to end the playback mode, and if YES, proceed to step 3
Return to 04.

In Figure 3, for multiple registered schedules, when the presence of a person is detected, the synthesized voice of the scheduled time and the corresponding scheduled event is output in the order of scheduled times temporally closest to the human body detection time. It's showing. While the system is detecting the presence of a person, it notifies you of the schedule, so you can only know the schedule you need.

Note that the embodiments of the present invention are not limited to the upper side only (within the scope of the gist of the present invention, various configurations or structures may be implemented).

(Effects of the Invention) As can be understood from the above explanation, according to the present invention, daily scheduled events and scheduled times can be registered very easily by voice, and from the time when the presence of a person is detected by the human body detection device. Since voice notification is provided only when there is a schedule registered within a certain period of time up to a predetermined time, it is possible to efficiently and reliably know about important schedules.
