  The audio playback units 211 to VoIP units 217, which are functional units, perform processing of audio data, audio signals, and the like in accordance with the respective functions, and have an interface control function with the CPU 110 unified for each functional unit. The CPU i / f control unit 220 and a voice input / output control unit 230 serving as an interface control function between a voice input / output unit unified for each functional unit. That is, the interface with the voice processing system is separated into an interface with the CPU 110 and an interface with the voice input / output unit 130, thereby realizing load distribution of the information amount by function integration.

The voice input / output control unit 230 performs interface control with the voice input / output unit 130 through which voice signals and the like are transmitted and received.

  Next, each functional unit of the integrated speech processing software will be described.

  The voice / PB (Push Button) detection unit 214 is a functional unit that monitors and detects whether there is a specific voice pattern or PB signal in the component of the voice signal input from the voice input / output control unit 230. .

  The audio conference unit 215 performs audio information processing when realizing the audio conference service. The audio conference unit 215 synthesizes a plurality of audio signals input from the audio input / output control unit 230 by an N-1 addition method. This is a functional unit that performs and outputs the synthesized audio signal to the audio input / output control unit 230.

  The VoIP unit 217 converts voice data received from the network via the LAN port 150 into a voice signal and outputs the voice signal to the voice input / output control unit 230. The voice signal input from the voice input / output control unit 230 is converted to the LAN. It is a functional unit that converts audio data to be transmitted to the network via the port 150.

  Note that the functional units are not limited to the audio reproducing unit 211 to the VoIP unit 217 as in this embodiment, and various functional units can be added. Also, which functional unit of the integrated speech processing software is used is set in advance from a maintenance terminal or the like not shown by the maintenance person for each user to use depending on the number of functional units used and whether each functional unit is necessary or unnecessary. In accordance with the set information, the voice service software 121 determines that the integrated voice processing software 122 is instructed to activate the functional unit to be used. As described above, the memory allocation is dynamically performed so that the memory can be efficiently used by the combination of the functional units to be used.

  As a result of the addition of the functional unit, even if the implementation configuration exceeds the processing capability of the DSP 140, by selecting the functional unit according to the instruction of the integrated voice processing software 122, it is reduced below the processing capability of the DSP 140. Processing can be executed.

  The operation of the speech processing system according to the present invention will be described below with reference to FIG. FIG. 3 is a diagram showing the operation of the speech processing system.

  When a communication device such as an IP exchange is turned on, the voice processing system is activated (S301). First, the program of the voice service software 121 stored in the flash memory 120 is copied to the RAM 112 built in the CPU 110 (S302). Then, the CPU 110 copies the program of the integrated voice processing software 122 stored in the flash memory 120 to the RAM 142 built in the DSP 140 (S303). The integrated sound processing software 122 is executed by the DSP 140 (S304).

  For example, when the DSP 140 performs voice information processing for voice calls by the VoIP unit 217 of the integrated voice processing software 122, the voice service software 121 causes the CPU 110 to the DSP 140 according to information set in advance by a maintenance person or the like. Then, the activation instruction of the VoIP unit 217 in the integrated voice processing software 122 is issued via the CPUi / f control unit 220 of the integrated voice processing software 122 (S305). When the VoIP unit 217 is executed, the voice information is processed by the VoIP unit 217 according to a function module execution instruction from the CPU 110 that executes the voice service software 121, and a voice call service is provided (S306).

  When voice data is received from the network via the LAN port 150 during a voice call, the CPU 110 receives the voice data. Then, the audio data is transmitted from the CPU 110 to the DSP 140. The DSP 140 receives the audio data via the CPU i / f control unit 220, and the VoIP unit 217 is executed to convert the audio data into an audio signal. The converted audio signal is transmitted to the audio input / output unit 130 via the audio input / output control unit 230.

  When a voice signal is received through a voice input / output unit 130 from a communication terminal such as a telephone terminal (not shown) during a voice call, the voice signal is transmitted to the DSP 140. The DSP 140 receives the audio signal via the audio input / output control unit 230 and the VoIP unit 217 is executed to convert the audio signal into audio data. The converted audio data is transmitted to the CPU 110 via the CPU i / f control unit 220. The CPU 110 transmits the audio data to the network via the LAN port 150.

  In addition, when the integrated audio processing software 122 as shown in FIG. 2 is used to execute processing in which a plurality of functional units cooperate, for example, when the audio playback unit 211 and the audio recording unit 212 cooperate to execute processing. It is possible to provide a service with reduced processing time.

  In this embodiment, the activation instruction of the functional unit is given in accordance with information set in advance by the maintenance person, but it is determined whether or not the voice service software 121 is compatible with the service to be used. An activation instruction can also be given.

  Moreover, even if the integrated voice processing software 122 is the same by mounting a plurality of DSPs 140, the function can be realized by specializing the purpose of use by changing the activation instruction of the functional unit for each DSP 140. At this time, a convenient functional unit such as the audio reproduction unit 211 and the audio recording unit 212 may be executed on the same DSP 140.

  Furthermore, in this embodiment, the audio processing system has been described as an example. However, in the case of a data processing system using the DSP 140, the same applies to video information, music information, etc. by reviewing the configuration of the functional unit. The function can be realized.
