Circuit arrangement for a telephone apparatus

Abstract

Abstract 1. Circuit arrangement for a telephone apparatus having a speech recognition and evaluation unit (AW) connected with a microphone (M), which converts spoken words characterizing numerical values and commands for example in binary numerical values or command words and forwards the numerical values to a transmitter for dial pulses (S), where-upon a dial number is transmitted automatically in the terminal line (a/b) of the telephone apparatus triggered by a command word, whereby the speech recognition and evaluation unit (AW) has a memory (SSP) with the characteristical sound pattern of the numerical values and the command words, and the recognition of the spoken numerical values and commands is performed by the comparison of the sound pattern of those with the stored sound pattern, characterized in, that in the speech recognition and evaluation unit (AW) the individual sound pattern of one or several numerical values significant to one or several persons are stored additionally to the characteristical sound pattern, that these sound pattern are also used for comparison and that the transmission of a dial number is only performed, if the individual sound pattern of one or several digits of the dial number correspond with the concerning sound pattern of the spoken numerical value.
