Abstract

A method is provided for generating a control command from a verbal statement that contains unrestricted phrasing and user-specific terms. The method includes the acts of: a) recording a voice command that has a multiplicity of words as an audio data stream by a recording device; b) sending of the audio data stream via a network to a first voice recognition device; c) reception of at least one data packet from the first voice recognition device, wherein the data packet contains information concerning which words in the audio data stream have not been recognized; d) at least partial recomition of the words that have not been recognized by the first voice recognition device by a second voice recognition device using at least one database; e compilation of the results from the first and second voice recognition devices to form a control command; and f) output of the control command.

Claims

1. A method for generating a control command, the method comprising the acts of:

a) recording a voice command as an audio data stream by a recording device, the voice command comprising a multiplicity of words;

b) sending the audio data stream via a network to a first voice recognition device;

c) receiving, via the network, at least one data packet from the first voice recognition device, wherein the data packet contains information concerning words in the audio data stream that were not recognized;

d) at least partially recognizing, via a second voice recognition device using at least one database, the words in the audio data stream that were not recognized by the first voice recognition device;

e) compiling results of the first voice recognition device and the second voice recognition device into a control command; and

f) outputting the control command,

2. The method according to claim 1, further comprising the act of:

g) identifying the unrecognized words in the audio data stream by the first voice recognition device and preparing the data packet by the first voice recognition device.

3. The method according to claim 2, wherein the act g) comprises:

identifying the unrecognized words in the audio data stream by time and/or position information within the audio data stream.

4. The method according to claim 2, further comprising the act of:

h) processing the at least one data packet by a processing unit and sending the words marked as unrecognized to the second voice recognition device.

5. The method according to claim 1, wherein the act 0 comprises:

transmitting the control command, via a vehicle bus, to at least one receiver in order to control functions.

6. The method according to claim 1, wherein the act b) comprises:

sending the audio data stream via a public network.

7. The method according to claim 6, wherein the public network is a mobile communications network.

8. The method according to claim 4, wherein devices provided to carry out acts a) to f) and h) are interconnected by wire and/or short-range wireless communication,

9. The method according to claim 8, wherein the short-range wireless communication is Bluetooth.

10. A system for generating a control command, the system comprising:

a recording device for recording a voice command that comprises a multiplicity of words;

a storage medium having at least one database;

a device that receives at least one data packet from a first voice recognition device, wherein the data packet contains an identification of unrecognized words in the voice command and

a second voice recognition device that analyzes and recognizes the identified unrecognized words using the at least one database.

11. The system according to claim 10, further comprising:

a processing unit of the second voice recognition device, wherein a wired and/or a short-range wireless connection is provided between the processing unit, the recording device and the storage medium.

12. The system according to claim 11, further comprising:

a server having the first voice recognition device, wherein a wireless connection is provided via a public network between the processing unit and the server.

13. The system according to claim 12, further comprising a vehicle, wherein the processing unit, the storage medium and/or the recording device are component of the vehicle.

14. The system according to claim 13, wherein the processing unit is configured to transmit a control command via a vehicle bus to a receiver in order to control functions of the vehicle.

15. A computer product comprising a non-transitory computer readable medium having stored thereon program code that, when executed by a processor, causes:

a) recording a voice command as an audio data stream by a recording device, the voice command comprising a multiplicity of words;

b) sending the audio data stream via a network to a first voice recognition device;

c) receiving, via the network, at least one data packet from the first voice recognition device, wherein the data packet contains information concerning words in the audio data stream that were not recognized;

d) at least partially recognizing, via a second voice recognition device using at least one database, the words in the audio data stream that were not recognized by the first voice recognition device;

e) compiling results of the first voice recognition device and the second voice recognition device into a control command; and

f) outputting the control command.
