Abstract

PURPOSE:To attain the input of code with the forming of conversation without losing the timing, by performing questionnaire with voice synthesis from a device being an objective of control. CONSTITUTION:When any voice signal is inputted to a telephone line 1 to an input signal detecting circuit 5, an output 6 turns to H level. A data selector 9 selects arbitrary synthesis information from an ROM10 with an address signal 11, and outputs is as a data 12. A voice synthesis circuit 8 operates the data 12, D/A-converts it into a voice and outputs it as a signal 13. This voice processing is started when a start signal 14 turns to H level, and the circuit 8 outputs an H level signal to a stop signal 15 when the voice processing for one syllable is finished. An amplifier 7 amplifies the signal 13 and transmits it on a line 1 via a coupling transformer 4.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device capable of remote control by voice, and relates to activation of remote control.

In an answering machine that allows the reproduction of recorded messages by remote control, the remote control must be able to be activated only by the user himself/herself.

Conventionally, methods of starting with an oscillator that oscillates at a specific frequency, or methods of starting with a special combination of oscillation signals, such as a control signal based on FSX modulation, have often been used. However, either method requires carrying an oscillator. In recent years, there has been a trend toward using a method of activating remote control using a human voice, which eliminates the need to carry the oscillator described above.

Voice pattern recognition is a possible method for activating the device using real voice, but it currently has a cost disadvantage. On the other hand, any group of numbers below c is called a code. ) is a key word, and there is a method of starting remote control by expressing and inputting it with your real voice, and this has the advantage of being able to be realized at a low cost. Conventionally, devices have been commercialized that use a method of setting a binary code and expressing it by the presence or absence of audio.

A major drawback is that it is easy to miss the timing to emit the sound.

These problems are not limited to telephone answering machines, but are common to all low-cost devices that are activated by voice.

An object of the present invention is to easily specify a % bar code using real voice. The purpose is to provide a voice remote control method.

Therefore, the present invention makes it possible to input a code in an interactive manner without missing a timing by asking a question using voice synthesis from the device to be controlled.

Hereinafter, nine embodiments of the present invention will be explained with reference to FIG.

Reference numeral 1 designates a busy line, 2 a call signal detection circuit, and 5 a relay. 4 rfi coupling transformer, 1 to 1 phone line
Provides and receives signals between roads. 5 is an input signal detection circuit;
When some audio signal is input from the telephone line 1, its output 6 becomes 1H" level. 7 is an amplifier, 8 is a speech synthesis circuit (for example, Hitachi HD588130), 9 is a data selector, and 10 stores PARCOR coefficients, etc. ROM
(Read-only memory) In response to the address signal 11, the data selector 9 selects arbitrary composite information from the aROM 10 and outputs it as data 12. The speech synthesis circuit 8 calculates the data 12, performs D/A conversion, converts it into speech, and outputs it as a signal 16. This audio conversion process starts when the start signal 14 reaches the aHw level, and
When the vocalization of the syllable is completed, the speech synthesis circuit 8 outputs a 'H' level signal as the stop signal 15.Amplifier 7
amplifies the signal 13 and sends it to the 1111 via the coupling transformer 4. 15.17 is a one-digit number storage circuit.

18 is a counter. 19 is a device to be controlled. 20 is a sequencer composed of a microcomputer.

FIG. 2 shows a flowchart of the processing of the sequencer 20.

The operation will be explained according to this. First, sequencer 20
waits until the call is made. (Sl) When a calling signal is input from line 1, it is detected by detection circuit 2. This output signal 21 causes the sequencer 20 to turn on the relay 3, thereby connecting the circuit a1 and the coupling transformer 4 (S2). Next, the sequencer 20 outputs the address signal 11 so that the data selector 9 selects and outputs the composite information data of "Hito-Kateme" in the ROM 10. S3) Then, the start signal 14 is set to the IHII level.

(S4) As a result, the synthesized information data of "Hitoketame" is converted into speech by the speech synthesis circuit 8. This is amplifier 7.
The signal is transmitted to the telephone line 1 via the coupling transformer 4. Next, the sequencer 20 waits until the utterance is finished. (ss)
When the utterance of "r Hitoketame" is finished, stop signal 15
becomes the 1H'' level, and the sequencer 20 clears the counter 18 to 1'0''. (16) Next, the address signal 11 is outputted so that the data in the ROM 10 corresponding to the value of the counter 18 is selected. (S7) For example, if the value of counter 18 is ``0#'', it will say ``Zero?
If the data of the phrase "Ite?" is '1'', it is sufficient to output the address signal 11 such that the data of the phrase "Ite?" is selectively output. Next, the sequencer 20 receives the start signal 14
is set to 1H" (S8), thereby the word is vocalized and transmitted. Next, wait until the utterance is finished. (89) When the utterance is finished, the stop signal 15 becomes ``H'' level.

Thereby, the sequencer 20 starts a timer that determines the time to monitor the presence or absence of voice input.

(810) Next, it is monitored once from ll11 to see if there is a voice input, and this is repeated until the timer time expires. (S11) If there is no audio input for a certain period of time, the sequencer 20 increments the counter 18 by one, and if the value is 10 or less.

The processing from S7 is continued again. (S12) On the other hand, if the value is 10, it means that none of "0" to "9" has been specified, and it is determined that the control of the AM device 19 is unnecessary, and the relay 5 is turned off. 9 times 111 and the connection between the circuits are opened and the state returns to the standby state for the ring tone. (On the other hand, when audio is input in process 811, it is detected by the detection circuit 5, and its output signal 6 becomes "H# level." As a result, the sequencer 20 sets the value indicated by the counter 18 as the first digit. It is determined that the code has been input, and the process moves on to comparing it with a preset code.Now, the code is assumed to be a two-digit number, and the first digit is stored in the memory circuit 16 and the first digit is stored in the memory circuit 17. It is assumed that the second digit is arbitrarily set in advance.The Zoken sensor 20 compares the value of the counter 18 and the value of the memory circuit 16.In other words, it determines whether the first digit of the code matches. (S
f4) If you don't scatter.

Turn off the relay 5 and return to the waiting state for a call signal.

(815) - If successful, proceed to the matching process for the second digit of :7. As described above, the sequencer 20
Send out the audio of 7 Taketamej.

(815) The utterance from 'O'' to '9' and the voice input are monitored. (815) If voice input is received on the way, the value of the counter 18 and the value of the memory circuit 17 are compared. In other words, it is determined whether the second digit of the ``7'' character matches. (
817) - I have to scatter.

Turn off relay 5, return to the waiting state for the call signal,
- In case of failure, remote control is activated and 9 equipment 190 control salt treatment is performed. (818) In the above process flow, the caller 9 says, “Hitoketame.
O? , 1? ...9? . "Futaketame, 0? 1?...
・9? . ", and after asking for the number of each tube of the code you want to input, "Ha-6J, ryE
If you make sounds such as s and J, you will be in trouble. In the example in Figure 1, the code is 12, so “Hitoketame, ot1t
, J You can start remote control by inputting the code by saying ``Yes.'' ``Futaketame, O?1?2?.''``Yes.''

Therefore, according to the present invention, the code is input in an interactive manner in which the code is answered in response to a question posed by one device, which has the effect of eliminating the drawback of the prior art in that the timing of input is likely to be missed.
