Abstract

PURPOSE:To decrease possibly malfunction by using the 1st and 2nd voices so as to apply processing at an incoming call. CONSTITUTION:When the telephone set 1 receives an incoming call and the level of a voice input signal from a microphone of a speakerphone 2 exceeds a prescribed level for a prescribed time, an output of a detection circuit 3 stops ringing of a call tone by a prescribed voice recognition section T. Then the 2nd voice input signal predetermined for the section T is recognized by a recognition circuit 4. In response to the recognition, a telephone line is connected via a talking circuit 6 to attain the talking mode.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an answering system for a telephone equipped with a speakerphone function having two W1 functions, a speaker and a microphone, and a function of detecting voice.

BACKGROUND ART Traditionally, telephones with a so-called speakerphone function have a switch for the speakerphone, and by pressing this switch when receiving a message, a talking state is achieved. Therefore, even though it has a speakerphone function, you cannot make a call unless you get within arm's reach, and even though it has a speakerphone function, this function cannot be used until (-minutes). I couldn't perform.

Problem to be Solved by the Invention 7 [χ The object of the present invention is to solve the above-mentioned technical problem 5, and to provide a telephone response capable of enabling a telephone call state without any manual operation when receiving a call. The purpose is to provide a method.

Means for Solving the Problems The present invention provides a response method for a telephone that receives a call signal via a telephone line and displays a call indication, and provides a method for responding to a call signal from the microphone during the period in which the call indication is being performed. means for level discriminating the first audio signal; and in response to the output from the level discriminating means, when the audio signal from the microphone exceeds a predetermined level;
A voice recognition circuit that identifies a second voice signal input from the microphone after that, and a hand r2 for setting a telephone conversation state corresponding to the second voice from the microphone in response to the output from the voice recognition circuit. This is a telephone response method characterized by:

According to the present invention, during the period in which the call display is being performed, the level discrimination means detects the first signal from the microphone.
The audio signals are level-discriminated.

By this level discrimination means, when the first audio signal exceeds a predetermined level, the fPJ2 audio signal that is subsequently input from the microphone is identified by the audio recognition circuit. When the second voice is identified by this voice recognition circuit, the telephone line is closed and a collocation state occurs. Therefore, without having to manually turn off the speakerphone P! It becomes possible to make full use of one's abilities and talk to incoming calls.

Embodiment @i Figure is a block diagram of one embodiment of a telephone according to the present invention. This telephone 1 includes a speakerphone 2, a level detection circuit 3 that detects the sound pressure level of an audio signal from the speakerphone 2, a voice recognition circuit 4, a ringing tone generation circuit 5,
It includes a telephone communication circuit 6 and a control circuit 7 for controlling such a circuit. The speakerphone 2 is an acousto-electrical transducer that has the function of a speaker that converts electrical signals into sound and the function of a microphone that converts audio into electrical signals, and is called a speakerphone in this embodiment. I'll decide.

This audio input signal from the speakerphone 2 is given to a level detection circuit 3 and an audio 'fJpn circuit 4.

When a ringing signal is applied to the ringing tone generating circuit 5 via the switching network 8, the ringing tone generating circuit 5 emits a ringing tone. Accordingly, the control circuit 7 activates the speakerphone 2.

Furthermore, when the control circuit 7 receives a detection signal from the level detection circuit 3, it activates the speech recognition circuit 4. When the control circuit 7 receives an identification signal from the voice recognition circuit 4 indicating that it has been identified, it activates the communication circuit 6, thereby closing the line and entering a communication state.

Figure 2 shows the processing operation of telephone bill 1 during X1 call.
0-chart, and FIG. 3 is a timing chart showing the timing of the voice detection state at the time of incoming call. At step n1, the telephone 1 enters the incoming call state, and the ringing tone generation circuit 5 generates a ringing tone. This ringing tone has a ringing period M1 and a stop period M2, as shown in FIG. 3(1), and these periods M1 and M2 are repeated alternately. The ringing period M1 is, for example, 1 second, and the stop Jjl1 interval M2 is, for example, 2 seconds.

Next, in step n2, it is determined whether or not the ringing tone is ringing. If it is ringing, step n3
One step later, the microphone of speakerphone 2 is activated. That is, the sound detection interval WI for detecting the sound pressure level of the audio signal from the microphone is determined, and the microphone of the speakerphone 2 is activated for sound detection in this sound detection interval W.7 This sound detection interval W is calculated as shown in FIG. (2)
As shown, this corresponds to the ringing tone stop period M2 for detecting the sound pressure level.

In step n4, the level detection circuit 3 determines whether the sound pressure of the audio input signal from the microphone provided in the speakerphone 2 has a bell at a predetermined discrimination level of 0 or higher and continues for a period of 1 or more. be done. Figure 3 (3
), for example, when the audio input signal indicated by reference numeral 1 is at the discrimination level 0 or higher from time 1 and this state continues for a period γ, the process moves to step n5 at elapsed time t2! @3 The ringing tone stops for a predetermined voice recognition interval T shown in Figure (4). This allows for accurate speech recognition without being affected by noise.

Note that the audio input signal may have its Yf IE level equal to or higher than the discrimination level 0 during the ringing period Ml, for example as shown in reference numeral 2 in FIG. . The ringing tone stops from time L' after a period γ.

Next, the process moves to step n6, and in this voice recognition section T, the voice input signal of predetermined fjS2 is identified by the voice recognition circuit 4. This second voice is, for example, "Hello".

In step 117, it is determined whether or not it is a predetermined second audio input signal. When the voice recognition circuit 4 identifies the voice input signal from the microphone of the speakerphone 2 as a predetermined second voice signal,
Proceeding to step n9, the telephone line is closed by the telephone call circuit 6, and the speaker function of the speakerphone 2 is activated, and in step n9, the telephone line is set to a telephone call mode.

In step n7, if it is not the second audio input signal, the process moves to step nlo, where it is determined whether a predetermined period T has elapsed. If the time has not elapsed, the process returns to step n6.

When the elapsed time has elapsed, the process moves to step 1111 and the ringing tone is generated again. Then return to step entrance 2.

In step n4, if the first audio input signal is longer than θ and does not continue for longer than γ, the process returns to step 2.

In this way, when an incoming call is received, processing is performed using two voices, the first voice and the second blind voice, so that malfunctions can be reduced as much as possible. Also enable speakerphone +l! You can move around freely and talk to multiple phones without having to worry about paying your phone bill.

Effects As described above, according to the present invention, it is possible to make a telephone call at the time of XI call without having to perform a manual operation to turn off the telephone.
