The line interface 401 is transmitted to the telephone intermediary device 4.
Through the audio signal receiving means 407. The control means 402 controls the voice signal receiving means 4 if the call circuit is not set up between the telephone interrogator and the branch telephone.
The voice input to 07 is determined to be the name of the called party used as the ringing tone, and the switch 408 is operated to the side that executes the voice recognition means 409 that recognizes the input name "Izawa". Here, the name recognition is performed by the voice recognition means 4
09, using the feature pattern of the name for which the feature extraction is performed,
This is performed by collating each kana character standard pattern in the kana character standard pattern memory 410 and obtaining a series of standard patterns having a high collation value as a character string. The character string of the recognized name “Izawa” is stored in the called party name storage memory 411. The character string of the name "Izawa" stored in the called party name storage memory 411 is further converted into synthetic voice by the voice synthesizing means 412, and this conversion is repeated until off-hook from the branch telephone is detected.

To the converted synthetic voice "Izawa", the voice "I call you" is read from the message voice storage memory 505, and the voice "Izawa calls" is added. It is repeatedly transmitted from the telephone intermediary device 4 to the branch telephones 51, 52, 53 through the branch telephone interface 412.

Since the branch telephones 51, 52 and 53 perform exactly the same processing, the branch telephone 51 will be taken as an example to explain the processing.
