Line connection switching apparatus for connecting communication line in accordance with matching result of speech pattern
First Claim
1. A switching apparatus for switching a line which is connected to a telephone, to a facsimile device, in response to a speech command coming from the line, said apparatus comprising:
- means for discriminating between a speech signal and noise coming from the line, based on a predetermined threshold value;
first storing means for storing the speech signal discriminated by the discriminating means;
means for detecting the speech signal as a candidate of the speech command when a duration of the signal discriminated by the discriminating means falls within a predetermined range;
second storing means for storing a standard characteristic pattern of the speech command;
means for comparing a characteristic pattern of the speech signal detected as a candidate of the speech command with the standard characteristic pattern of the speech command; and
means for switching the line which is connected to the telephone, to the facsimile device when the characteristic pattern of the speech signal detected as a candidate of the speech command matches a standard characteristic pattern of the speech command in the means for comparing.

Abstract
A line connection switching apparatus performs connection switching of a communication line used both for speech communication performed by a telephone set and data communication performed by a facsimile apparatus and is inserted between the telephone set and the facsimile apparatus, and the communication line. When predetermined speech command information is input from a caller side through the communication line, a speech signal is detected by a switching unit. When a voice/silence discriminator discriminates that the speech signal represents voice, a voice interval monitor 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. A pattern matching unit verifies whether a standard speech pattern of a speech signal registered in standard pattern dictionary unit matches with a speech pattern of the input speech signal stored in the speech signal storage unit. In accordance with a verification result, if the speech pattern of the input speech signal coincides with the standard pattern, the switching unit switches connection of the communication line to the facsimile apparatus.
