Abstract

A hand-held lighting device includes a light source (18) and a switching device (26) for switching the light source on and off, and the switching device (26) includes a speech processor (34) for analyzing and/or synthesis of the spoken speech.

Claims

1. Hand-held lighting device comprising:

a light source and

a switching device for switching the light source on and off, wherein the switching device comprises a speech processor for at least one of analysis and synthesis of spoken speech

wherein the speech processor is configured to generate an output spoken text under certain conditions which are related to a state of the light source.

2. The lighting device according to claim 1, wherein the speech processor is configured for detecting a pre-defined code word and switching the light source on in response to recognition of the code word.

3. The lighting device according to claim 1, wherein the speech processor is configured for switching the light source off when a pre-defined code word is recognized.

4. The lighting device according to claim 1 further comprising a state sensor adapted to detect an open/close condition of a container in which the lighting device is carried.

5. The lighting device according to claim 4, wherein the switching device is configured for switching the light source off when the state sensor detects a closed condition of the container.

6. The lighting device according to claim 4, wherein the switching device is configured to activate the speech processor only when the state sensor detects an open state of the container.

7. Hand-held lighting device comprising:

a light source and

a switching device for switching the light source on and off, wherein the switching device comprises a speech processor for at least one of analysis and synthesis of spoken speech,

wherein the speech processor is configured to record spoken text and to store the spoken text for the purpose of at least one of a later recognition and generation of this text.

8. The lighting device according to claim 7, wherein the speech processor is configured for detecting a pre-defined code word and switching the light source on in response to recognition of the code word.

9. The lighting device according to claim 7, wherein the speech processor is configured for switching the light source off when a pre-defined code word is recognized.

10. The lighting device according to claim 7, further comprising a state sensor adapted to detect an open/close condition of a container in which the lighting device is carried.

11. The lighting device according to claim 10, wherein the switching device is configured for switching the light source off when the state sensor detects a closed condition of the container.

12. The lighting device according to claim 10, wherein the switching device is configured to activate the speech processor only when the state sensor detects an open state of the container.
