Abstract

PURPOSE:To inform who is a caller during a conference to other participants in a synthesis voice by providing a talker identification circuit identifying to which of N sets of input terminals an input comes, a voice display circuit and an adder circuit synthesizing the voice signal and a signal at an output terminal to the talking equipment so as to identify who is the caller during a conference. CONSTITUTION:When N-sets of input voice signals A-E are received by a conference speech circuit 1, the (N-1) sets of the signals among the received voice signals except a concerned input signal are added and a sum is outputted to each terminal as output voice signals a-e. Furthermore, the conference speech circuit 1 generates a sum of all the input voice signals other than the output voice signal a-e and provides an output of the sum to a talker identification circuit 2, which receives the sum of all the received voice signals and the sum of the (N-1) sets of the signals and identify a terminal without a signal to allow a caller to identify any of the input voice signals A-E, and the result is outputted to a voice display circuit 3, which receives the identification result to synthesize a voice signal used to inform who is a caller and it is added to an output of the conference speech circuit 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used in a conference call device. The present invention relates to a conference call device capable of identifying a speaker during a conference call and notifying who the speaker is by synthesized voice.

[0002]

2. Description of the Related Art A conventional conference call device cannot identify the voice of a speaker during a conference call, and other conference participants hear and judge the voice of each speaker to make a determination. Further, Japanese Patent Application Laid-Open No. 58-21961 discloses a technique of visually displaying information on a speaker.

[0003]

Since the conventional conference call device cannot identify and notify the speaker, it is necessary for each conference participant to identify who the speaker is. There was a problem that the meeting could not proceed smoothly when the participants joined the meeting.

The present invention solves such a problem, and provides a device capable of identifying who is a speaker during a conference call and notifying other participants by synthetic voice. To aim.

[0005]

According to the present invention, there are provided an input terminal to which a plurality of N input audio signals are applied, and a plurality of N output terminals provided corresponding to the input terminals and outputting an output audio signal. A conference call circuit (1) including a circuit for outputting a signal applied to the input terminal to all output terminals other than the output terminal corresponding to the input terminal, A speaker identification circuit (2) for identifying which terminal receives an input, a voice display circuit (3) for generating a voice signal for displaying a speaker according to the identification result, and the voice signal for outputting the voice signal. And an adder circuit (4) for combining with the signal of the terminal.

The voice display circuit (3) is a circuit for generating a synthetic voice, and means (1) for setting the content of the synthetic voice.
0, 11), the discrimination circuit (2) compares the added value of all input audio signals obtained by adding all the signals of N input terminals with the output audio signal sent to each output terminal, It is desirable to include a means for identifying the output terminal where the added value does not appear.

[0007]

The function of inputting the voices from a plurality of subscribers, outputting the voices of a plurality of subscribers, and adding all the input values from the conference call circuit for making a call between the plurality of subscribers to the speaker identification circuit Enter and identify who each speaker is. The voice synthesizing circuit synthesizes voices based on the identification result, and notifies each subscriber of who the speaker is by the synthesized voice. This eliminates the need for each subscriber to determine who is the speaker, and the conference can proceed smoothly.

[0008]

Embodiments of the present invention will now be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of the embodiment of the present invention.

In the embodiment of the present invention, an input terminal to which a plurality N of input audio signals are applied, and a plurality of N output terminals which are provided corresponding to the input terminals and which output an output audio signal are transmitted,
In a conference call device including a conference call circuit 1 including a circuit for outputting a signal applied to the input terminal to all output terminals other than an output terminal corresponding to the input terminal, which one of N input terminals A speaker identification circuit 2 for identifying whether there is an input at the terminal, a voice display circuit 3 for generating a voice signal for displaying the speaker according to the identification result, and an adder circuit 4 for synthesizing the voice signal into a signal at an output terminal. With.

The voice display circuit 3 is a circuit for generating a synthetic voice, has a computer device 10 and an operating terminal 11 as means for setting the content of the synthetic voice, and has a speaker identifying circuit 2
Includes means for comparing an added value of all input audio signals obtained by adding all signals of N input terminals with an output audio signal sent to each output terminal, and identifying an output terminal in which the added value does not appear. .

The present embodiment shows a conference call device that enables a conference call by five parties, and performs a conference call by the N-1 addition method. That is, when N input voice signals A to E are input to the conference call circuit 1, N-1 signals of the input voices excluding its own input are added, and the added values are output voice signals a to e. Is output to each terminal as. In addition to the output voice signals a to e, the conference call circuit 1 generates an added value of all input voice signals to generate a speaker identification circuit 2.
Then, the speaker identification circuit 2 receives the added value of all the input voice signals and the N-1 added value as inputs and identifies a terminal having no signal to identify which one of the input voices A to E the speaker is. Then, the identification result is output to the voice display circuit 3.

The voice display circuit 3 synthesizes a voice, for example, "Speaker is Mr. Yamada", which informs who the speaker is, by inputting the identification result, and the synthesized voice is used for the conference call circuit. Add to the output of 1.

This synthesized voice can be set before the start of the conference. An example thereof can be input and set by operating the computer device 10 connected to the voice synthesizing circuit 3 and its operating end 11.

Computer device 10 and its operating end 1
When 1 is inaccessible by the conference organizer or its instruction, it can be configured to connect to the computer device 10 using a telephone line and perform an input operation.

The output synthesized voice signal of the voice display circuit 3 can be shot (reduced or silenced) by an operation after starting a conference call, by a timer, or by a set number of times of speech.

In this way, the voice obtained by adding the output voice of the conference call circuit 1 and the synthetic voice of the voice display circuit 3 is output as the output voices a to e, so that who the individual speakers are is You can recognize without having to judge each time.

[0017]

As described above, according to the present invention, the voice of a speaker can be identified during a conference call, and other conference participants can be notified by a synthetic voice. There is an effect that a conference can be smoothly conducted.

The present invention requires means for transmitting information for identifying a speaker to each conference terminal, as compared with the above-mentioned conventional technology for visually indicating who is the speaker. On the other hand, in the present invention, since it is not necessary to transmit the information for identifying the speaker only by synthesizing the voice at the output terminal of the conference call circuit, the apparatus can be provided as such an inexpensive apparatus.
