Description

DETAILED DESCRIPTION OF THE INVENTION The present invention particularly relates to an audio device that controls the operation of electrical equipment based on a speaker's audio signal.

[Technical background of the invention and its problems]

2. Description of the Related Art In recent years, audio devices that use audio signals to turn on electrical equipment, etc., have been widely used in various fields. For example, there is a device in which the above-mentioned audio device is connected to an answering machine. In such a device 11', when the external line d'tn δ is reached through the old line, normal answering machine operation is performed without any interruption, and then the audio device ifK
The voice is manually transmitted from the city's 4th line.

The audio device M recognizes the input voice and controls electrical equipment etc. based on the recognition result.

If such a device is used, for example d: the user can
) Call the phone on the way home and check the cooling device in the residence in advance.
It has the advantage of keeping the power on and keeping the inside of the house cool.゛If the user is still away from home for a long period of time, make sure that all electrical equipment in the residence is turned off from outside the home (11n), and if the user is away from home, check that the electrical equipment in the residence is turned off (11n), and if it is turned on, You can turn it off.

By the way, the conventional audio device C as mentioned above is generally used as a speech recognition unit! Uses speech recognition equipment for specific speakers. In other words, f:r.昌/" (The train records the user's voice in advance) and recognizes the voice. If L is based on the result, Jl 1j like "
U-Ki (i-control devices, etc.). This is due to the voice recognition '4 < 4 ffi, which has a high rate of rejection when the voice of someone other than the user is input. However, with conventional audio devices, when recording 7Kt of sound from multiple users (even on the same single unit), when someone else's voice is input, it is impossible to prevent other people from using it. There is a disadvantage that there is a high probability of false recognition.In this case, for example, if a switch such as ``L air pump'' is turned on by mistake, there is a risk of fire, etc. It turns out.

[Purpose of the invention]

This invention was made in view of the above circumstances, and is designed to reliably prevent the voice recognition device from erroneously operating due to the voice of someone other than the user, so that it can always be used even in the case of highly dangerous electrical equipment. To provide a voice device which can reliably control ``I+1+'' using a person's voice.

[Summary of the invention]

That is, in this invention, for example, keywords consisting of a predetermined combination depending on the risk level of ri electrical equipment are expressed as 1.

This voice recognition device Y-4 pre-memorizes a keyword consisting of a combination of r9 digits (for example, voice IIζ; such as right-on, strike-on, etc.), and inputs the following into the keyword: ;i!;, performs the recognition process for the above speech S.Furthermore, the blind j'i'' jiJ knowledge 11i is the 'ilj source switch (C: 1 path 5) based on the 1 recognition result.

The voice response device 6 generates, for example, a message confirming the reception of the voice S based on the recognition results of the voice and the recognition fist 4, and changes the output of the message via the switch circuit 3. and send it to telephone line 1.

The operation in such a 4'fI'i' configuration will be explained. The changeover switch circuit 3 operates as a switch so that the regular telephone line 1 and the answering machine 2 are connected. If the call is connected from an outside line via '[L episode 1'], the answering machine'rt5 episode 2 will operate as a normal answering machine, that is, it will be the voice S from the caller (the caller).

In this case, the other voice Nagisa disconnects the telephone line. If the changeover switch circuit 3 does not operate as described in Section 2, 1. I am away from home - vinegar? It is connected to the IQ speaker 2. ”L#: Each device 6 notifies the speaker to urge him/her to utter the keyword. However, this operation is not always necessary.

Here, speaker t, utter a predetermined keyword according to the electrical equipment to be controlled! -I do.

The uttered voice S is input to the voice H2 identification system 4 via the telephone line 1 and the changeover switch circuit 3. The voice recognition device 4 recognizes the input voice jS based on the keywords written and selected in advance as described above. Such keywords may be set in combination depending on the degree of danger of the electrical equipment, for example. Ru.

Specifically, even if someone else becomes the speaker and controls it, there is not much danger, for example [, 1, electricity like a light + 9. In the case of a container, a simple combination of keywords such as "light off" or "light men" is added. In the case of dangerous electrical equipment (for example, an electric stove), if someone else carelessly controls it, it may be ``fire'', ``dangerous'', etc.
A unique combination of keywords such as "stove on" is provided.

In addition, 'tli TA aircraft, which is somewhat less dangerous); 1 ÷ (
For example, in the case of an electric kotatsu (electric kotatsu), "fire", "kotatsu on"
