Abstract

PURPOSE:To transmit voice information with the content of desired service and types of languages from a common storage reproducer, by storing a plurality of audio information different from types of service content and languages as digital signals. CONSTITUTION:When an extension is connected to a voice information trunk IFT via a channel switch for, e.g., a morning call, a central controller transmits designated information signals LI relating to the types of service content and languages to a stored reproducer REVC. The REVC analyzes the LI at a designation information analysis circuit LA, gets the start address of voice information memory MEM where a digital signal of corresponding voice information is stored to a register RAR and starts a control circuit CNT-R. The CNT-R transmits digitalized voice information DVI to the IFT sequentially in a high speed and to the extension via the channel switch.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a wake-up call service for extension telephones in a storage program controlled private branch exchange, particularly in a hotel electronic exchange.

This relates to another audio information transmission method.

For example, in order to provide voice wake-up call services, various guidance/notification services, etc. to guests at a hotel, etc., it is essential for the service to transmit voice information in the relevant language (Japanese). This is 1 usually,
It is necessary to speak at least six languages (Japanese, English, French, German, Spanish, Chinese, etc.).

FIG. 1 is a relay system diagram of an example of a conventional multi-side audio information transmission system, and is for a wake-up call service of a hotel telephone exchange.

First, when a guest checks in to a guest room with an extension telephone EXT, the terminal PO8 installed at the front desk etc.
The language type of the guest is host computer H.
The information is sent to the central control unit CC via the CPU and the interface control unit fIFc, and the language type information regarding the extension telephone EXT is stored (registered) in the main memory MM.

Next, when the extension telephone EXT sends the specific i number dial for registering the wake-up call service and the dial for the desired wake-up time as service request information to the calling register (not shown) via the call path switch SW, the known After receiving and analyzing these dial information, the central control device CC stores the extension number of the extension telephone EXT and the wake-up time in the main storage device MM,
The registration of service request information a for the wake-up call service is completed.

Thereafter, the central control device CC monitors the clock device MTM at a predetermined period (for example, a 1-minute period) to check and verify whether the registered wake-up time has arrived, and confirms that the time on the clock device MTM and the registered wake-up time are correct. If there is a match, the extension telephone EXT is called using a known method.

When the extension telephone EXT goes off-hook (when the guest answers), an empty wake-up call trunk M
CT (≠1 to 〇) is selected and captured, and the extension telephone EXT is connected to it via the call path switch SW, and the language type is selected according to the language type information stored in the main memory device MM. Applicable recording and playback device TRC (≠

Therefore, the recording/playback device TRC must be provided independently for each language type, and the connector relay of the connecting device CON is required depending on the number of language types. It will also be huge.

In addition, other information/notification services, such as registration completion notification voice information for registration of wake-up call service (for example, information such as "Registration for wake-up service has been completed. Please take a good rest.") If you try to send out a wake-up call service, you will need many other types of recording and playback devices and connection devices for the wake-up call service reception trunk.

In this way, the conventional method requires a recording/playback device for each type of audio information, and also requires a recording/playback device for each type of audio information.
Since it requires a large amount of connection equipment between the reception trunk and the reception trunk, it is not economical and the equipment is also large.

SUMMARY OF THE INVENTION An object of the present invention is to overcome the drawbacks of the prior art described above and provide an economical multi-side audio information transmission system that allows audio information to be transmitted in desired service content and language types from a common storage/playback device. It's about doing.

A feature of the present invention is that a plurality of digital signals of audio information with different service content types or language types are stored in a plurality of audio information trunks that can temporarily store, reproduce, and transmit digital signals of arbitrary audio information. A storage and reproducing device capable of reproducing and transmitting the voice information to any rank of the above-mentioned voice information is provided in common, and the system is controlled by a central control unit in response to service request information from an extension telephone.
The desired service content type or language type is specified to the storage and playback device, and based on this, the digital signal of the audio information is transferred and stored at high speed from the storage and playback device to the audio information trunk. The present invention is a multi-channel voice information transmission system in which voice information is transmitted from a voice information trunk to the extension telephone in a predetermined signal format and speed.

Embodiments of the present invention will be described below based on the drawings.

Registration of language type information regarding extension telephone EXT.

For registration of the wake-up call service and connection to the voice information trunk IP'T (corresponding to the wake-up call trunk MCT in Figure 1), please refer to
Since it is the same as that explained with reference to the figure, the explanation thereof will be omitted.

In addition, the language type registration is not limited to the above-mentioned method, but can be done by the guest himself/herself using the extension telephone, by a person concerned (maintenance personnel, front desk staff, etc.) using the extension telephone, or by using a typewriter, etc. This can be done using an input device.

When the extension telephone EXT is connected to the voice information trunk IPT via the call path switch sw in order to make a wake-up call, the central controller CC, before or after that,
A trunk designation signal T'I is sent to the audio information traffic controller/IFT, and also.

Service content type for storage and playback device REVC.

A designation information signal LI regarding the language type is sent.

In the storage and playback device REVC, this specified information signal LI is received and analyzed by the specified information analysis circuit LA, and the audio information memory MEM stores the digital signal of the audio information according to the service content type and language type based on the result. The start address of is set in the read address register BAR, and the control circuit CNT-R is activated.

The control circuit CNT-R changes the control line C0NT from a low level to a high level, instructs the audio information trunk IFT to transfer audio information, opens the audio information gate G, and starts audio according to the above start address. Information memory M
The digitized audio information DVI is sequentially sent from the EM to the audio information trunk IFT at high speed.

On the other hand, in the audio information trunk IFT which has received the trunk designation signal TI, the clip-flop FF is set, and its output Q causes the gate circuit GT to
Since G2 is open, the control circuit CNT-T receives the audio information transfer signal on the control+IjiCONT, specifies the address in the write address register WAR, and transfers the digitized audio information DVI to the buffer memory B.
Write to M sequentially.

Note that both the control circuits CNT-4 and CNT-T are controlled by, for example, a clock signal C supplied from the central control unit CC.
High speed and synchronous operation is performed by LK.

When the storage/reproduction device FLEVC finishes sending out the digitized audio information DVI of a predetermined number of words, the control line C
0NT is set to a low level to instruct the audio information trunk IFT that the transfer of audio information has ended, and recovery is performed in preparation for the transfer of the next audio information.

As a result, the processing time is extremely short and it can be commonly used for many voice information trunk IFTs.

In addition, in the audio information trunk IFT, its control circuit CN
When T-T receives the transfer end signal or identifies that it has received a predetermined number of words, it resets the flip-flop FF, closes the gate circuit GT, and resets the digital data written in the buffer memory IJBM. The converted audio information DVI is read out at a normal playback speed, and the audio information signal in analog format is sent to the extension telephone EXT via the communication path switch SW through the digital-to-analog conversion circuit D/A. Note that this digital-to-analog conversion circuit D/A is unnecessary when the communication path switch SW is of a time-division type.
It is only necessary to cause M to transmit digitized audio information at a predetermined speed.

As a result, the guest in the guest room with the extension telephone EXT can receive the desired wake-up call service in the desired language.

Above, we have explained the voice information transmission method according to the language used by the guest regarding the wake-up call service.
Regarding other various guidance and notification services, the service code dial etc. is used as service request information, and the content of the service is stored and reproduced in advance by the language type on the R
By storing it in the EVC, it can be implemented in the same manner as described above. Note that it is clear that a single language type or multiple language types may be used depending on the service type.In short, it is possible to transmit various types of audio information according to the service content type and language type. can.

As described above in detail, according to the present invention, it is possible to commonly provide a storage and playback device, and to transmit desired types of audio information from a corresponding number of audio information trunks. Moreover, since the main parts can be constructed from electronic circuits using inexpensive ICs without using devices with mechanical parts such as tape recorders, related equipment can be significantly downsized and made more economical, and it is also reliable. The effect is remarkable.
