Line connection switching apparatus for connecting communication line in accordance with matching result of speech pattern

Abstract

Abstract A line connection switching apparatus (10) performs connection switching of a communication line (12) used both for speech communication performed by a telephone set (14) and data communication performed by a facsimile apparatus (16) and is inserted between the telephone set (14) and the facsimile apparatus (16), and the com­munication line (12). When predetermined speech command information is input from a caller side through the com­munication line (12), a speech signal is detected by a switching unit (18). When a voice/silence discriminator (20) discriminates that the speech signal represents voice′ a voice interval monitor (22) monitors a duration of the speech signal. If the duration of the speech signal falls within a predetermined range, the speech signal is stored in a speech signal storage unit (24). A pattern matching unit (26) verifies whether a standard speech pattern of a speech signal registered in standard pattern dictionary unit (28) matches with a speech pat­tern of the input speech signal stored in the speech signal storage unit (24). In accordance with a verifi­cation result, if the speech pattern of the input speech signal coincides with the standard pattern, the switching unit (18) switches connection of the com­munication line (12) to the facsimile apparatus (16).
