Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to improving the processing speed of a voice processing device that provides various services over the telephone.

(b) Background of the technology In general, a voice processing device is equipped with a telephone control unit and a voice response unit, and is capable of providing various services using a telephone.At first, the telephone was used to perform services such as checking the balance of a bank account. ing.

In this balance inquiry service 2, in response to a call from a subscriber, a voice processing device collects necessary data from the subscriber in a conversational manner, and then collects the balance t from the subscriber's file at the bank's center.
- Research and inform subscribers.

That is, in order to receive this service 1e, the subscriber first makes a call to the voice processing device in the same way as a normal telephone call.

When the voice processing device is notified of an incoming call by the network control device, it issues a command to occupy the line to the network control device, puts it in a state generally called hook-off, and starts the voice response unit r. and announces, "This is a branch of a bank. Please enter your PIN."

Upon hearing this announcement, the subscriber enters a predetermined password, for example, by pressing a Pufshehon button.

On the other hand, on the voice processing device side, the telephone system # section receives this Pup Soehon signal and stores the received banjime in a memory or the like. Next, the voice processing device sends a confirmation message to the telephone, and sequentially activates the voice response unit to prompt the telephone to input the account number, etc., and sends guidance to the telephone, which prompts the telephone to input multiple messages. The information received is received by the telephone control circuit in the same manner as described above.

This information is also stored in one place as described above.

This memorized information is then sent to the bank's center via a transmission line (flit), which compares the PIN number (e.g. with the subscriber file) and checks the account number, and only if the identity is verified, the account balance is voiced. It is sent to a processing device (9), where it is synthesized into voice and output to a telephone.

Thus, the speech processing device includes a speech synthesis section that allows a conversation between a computer and a person receiving signals from a telephone by means of a telephone control section.

In addition, as mentioned above, this voice processing device can carry out conversations with a series of subscribers by simply installing the voice processing device, and other types depend on the center.In addition, the data received from the telephone is the Pushephone signal as described above. If not, it also has a function to recognize signals sent by voice.Also, specific people can receive information at a fixed time every day, such as stock market conditions or weather forecasts. Sometimes it is communicated.

In this case, the voice processing device stores the timer, service details, and telephone number of the other party, and when the predetermined time comes, the voice processing device will call the phone number. After making a call and confirming that it is the other party, the predetermined service is performed.

((+) Prior art and problems By the way, the biggest problem with such voice processing devices is disconnection of the line during a conversation with the voice processing device, that is, when you are hooked on or when you cannot call the other party's phone. This is the case when 9 is not available or the call is busy.

In this case, the conventional method was to set a waiting time of about one minute and determine that the above condition occurred if there was no response during that time, but this method only occupied the line in the voice processing device during that time. However, there is a drawback that the processing device cannot perform other services during that time.

(d) Object of the Invention Accordingly, it is an object of the present invention to provide a novel audio processing device that eliminates the above-mentioned drawbacks.

(el) Structure of the Invention In order to achieve this object, the present invention is provided with at least a telephone control section and a voice response section, and allows the telephone control section to receive data from a telephone connected via a public telephone communication line. ) A voice processing device which receives voice information and also performs a voice response to a telephone using the voice response unit, is characterized by being provided with means for recognizing the busy tone and disconnection tone of the telephone.

Instructions to CU? The NCU provided is hooked off like a normal telephone line.

On the other hand, the CPU notifies the higher-level processing device of the incoming call via CMC=j(r), and waits for an instruction from the higher-level processing device.

Next, when the higher-level processing unit gives an instruction to output a message to the telephone, the CPU recognizes this instruction and sends a message to the telephone.
The voice parameters instructed from the voice file in M are sent to the voice synthesis circuit 1, which synthesizes them into voice and sends them to the telephone set.

The output from the speech synthesis circuit 1 is performed by switching the line switch Ill in response to an instruction signal from the line control section 2 (operated according to an instruction from the CPU).

On the other hand, since the telephone receives a response to the voice message from the voice synthesis circuit 1, the line switch 8 receives that signal? Is the signal input from the phone to be received switched so that it is input to the receiver PBR? Let's do it.

Is PBR a push-phone signal from a telephone? Receive it, convert it into a digital signal, and send it to the line control unit 2? to the CPU via the
