23. The system of claim 22, where the softkey is configured to control one or more electronic device and change at least one parameter.

24. The system of claim 10, where the speech dialog system is configured to power off upon detection of a relevant speech command.

25. The system of claim 24, where the speech dialog system is configured to power off upon absence of detection of a speech command during a predetermined period.

26. The system of claim 10, where the control key is configured to operate in a first manner and a second manner, where the speech dialog system is activated upon operation of the first manner.

27. The system of claim 26, where the first manner requires the control key to be operated longer than a threshold time period.

28. The system of claim 26, where the first manner requires the control key to be operated shorter than the threshold time period.

29. The system of claim 10, where the control key comprises a hardkey.

30. The system of claim 10, where the control key comprises a softkey.

31. A vehicle system comprising a system for controlling at least one electronic device having at least one control key, comprising:

a speech dialog system for controlling the electronic device, where the speech dialog system is activated upon an operation of the control key of the electronic device is operated; and

a vocabulary set for each electronic device configured to be operable by the speech dialog system and activated by the control key, where the electronic device is operated by the speech dialog system based on the activated vocabulary set.

32. A computer program product for use with a digital computer, the computer program product directly loadable into an internal memory of the digital computer and including one or more sequences of instructions for performing activating a speech dialog system for controlling at least one electronic device upon operation of a control key of the electronic device.

33. The computer program product of claim 32, further comprising one or more sequences of instructions for activating a predetermined vocabulary set corresponding to the operated control key.

34. The computer program product of claim 32, further comprising one or more sequences of instructions for terminating the speech dialog system upon detection of a corresponding speech command.

35. The computer program product of claim 32, further comprising one or more sequences of instructions for terminating the speech dialog system upon absence of detection of a speech command during a predetermined period.

36. A computer program product for use with a computer system, the computer program product comprising:
