Abstract

The operation and control of devices is made possible by a portable unit. Operation and control of devices, particularly telephone installations is a means of speech via a portable voice module. A portable voice module contains a digital signal processor (DSP), a memory (S), an analog-digital/digital-analog converter (AD/DA), an analog interface (ANALOG I/O), a computer interface (PORT) and a digital interface (DIGITAL I/O). A telephone installation consists of the portable voice module and a telephone device, which is composed of basic units and interfaces.
