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.

Claims

1. A telephone installation comprising:

a portable voice module for the voice-controlled operation and control of devices, comprising;

an analog/digital and digital/analog converter circuit (AD/DA), responsive to analog user voice and active vocabulary command input signals from an analog interface (Analog I/O), for providing digital user voice and active vocabulary command input signals, and further responsive to digital voice output signals, for providing analog voice output signals to the analog interface (Analog I/O);

a digital signal processor (DSP), responsive to digital input signals from a digital I/O interface (Digital I/O), responsive to computer interface input signals from a computer interface (PORT), and responsive to the digital user voice and active vocabulary command input signals, for providing digital data, computer interface data, or active vocabulary command and synthesized voice memory input signals, and further responsive to digital data, computer interface data, or synthesized voice memory output signals, for providing digital output signals to the digital I/O interface (Digital I/O), computer interface output signals to the computer interface (PORT), or digital voice output signals to the analog/digital and digital/analog converter circuit (AD/DA); and

a memory circuit (S), responsive to the digital data, computer interface data, or active vocabulary command and synthesized voice memory input signals, for providing the digital data, computer interface data, or synthesized voice memory output signals to the digital signal processor (DSP); and

a telephone device having a plug-in interface for receiving the portable voice module.

2. A telephone installation according to claim 1, in which spoken language is stored in the portable voice module.

3. A telephone installation according to claim 1, in which software programs are stored in the memory circuit (S) suitable for playing back speech, or to perform a hands-free telephone function.

4. A telephone installation according to claim 1, in which software programs are stored in the memory circuit (S) suitable for encoding voice for user guidance.

5. A telephone installation according to claim 1, in which the telephone device is a public telephone.

6. A telephone installation according to claim 1, in which the telephone device is a private telephone.

7. A telephone installation according to claim 1, in which the telephone device is a mobile telephone.

8. A telephone installation according to claim 1, in which the telephone device is a data processing device with a telephone operating function.

9. A portable voice module for the voice-controlled operation and control of devices, comprising:

an analog/digital and digital/analog converter circuit (AD/DA), responsive to analog user voice and active vocabulary command input signals from an analog interface (Analog I/O), for providing digital user voice and active vocabulary command input signals, and further responsive to digital voice output signals, for providing analog voice output signals to the analog interface (Analog I/O);

a digital signal processor (DSP), responsive to digital input signals from a digital I/O interface (Digital I/O), responsive to computer interface input signals from a computer interface (PORT), and responsive to the digital user voice and active vocabulary command input signals, for providing digital data, computer interface data, or active vocabulary command and synthesized voice memory input signals, and further responsive to digital data, computer interface data, or synthesized voice memory output signals, for providing digital output signals to the digital I/O interface (Digital I/O), computer interface output signals to the computer interface (PORT), or digital voice output signals to the analog/digital and digital/analog converter circuit (AD/DA); and

a memory circuit (S), responsive to the digital data, computer interface data, or active vocabulary command and synthesized voice memory input signals, for providing the digital data, computer interface data, or synthesized voice memory output signals to the digital signal processor (DSP).

10. A portable voice module according to claim 9, wherein the analog user voice and active vocabulary command input signals include active vocabulary commands such as a record command for recording language spoken in the memory circuit (S), a playback command for playing back the language recorded from the memory circuit (S), a start command for providing a start command signal to any device connected to the digital interface (DIGITAL I/O), an end command for providing an end command signal to the device connected to the digital interface (DIGITAL I/O), and a record measurement command for recording measurement value from the device connected to the digital interface (DIGITAL I/O).

11. A portable voice module according to claim 9, wherein the digital input signals from the digital I/O interface (Digital I/O) include voice or graphics digital input signals, and the digital output signals to the digital I/O interface (Digital I/O) include voice, graphics or external device command digital output signals.

12. A portable voice module according to claim 9, wherein the computer interface input signals from the computer interface (PORT) include measurement data or external device command input signals, and the computer interface output signals to the computer interface (PORT) include measurement data or external device command output signals.

13. A portable voice module according to claim 9, wherein the memory (S) stores a software program for voice encoding, voice recognition and voice commands and their corresponding functions.

14. A portable voice module according to claim 10, wherein the active vocabulary commands can be expanded to any size, and words can be added or deleted from a list of the active vocabulary commands.

15. A portable voice module according to claim 10, wherein the memory (S) stores a software program for voice encoding to instruct users, for voice recording, for notebook functions and to playback recorded language for call answering functions, for intercom uses.

16. A portable voice module according to claim 15, wherein the software program is speaker-dependent or speaker-independent.

17. Portable voice module according to claim 9, in which the portable voice module is designed in the form of a credit card.

18. A portable voice module according to claim 9, wherein the portable voice module can record and play back voice or picture data.

19. A portable voice module according to claim 9, wherein the portable voice module can record and play back data, particularly measurement data, through the computer interface PORT.

20. A the portable voice module according to claim 9, wherein the portable voice module provides the voice-controlled operation or control of a data processing device or a telecommunications terminal.
