Abstract

An electrically operated food processor with a mixing bowl and a mixer in the mixing bowl is provided with an acoustic transducer and with stored speech recognition software, it being possible to use speech recognition to cause the food processor to carry out a routine task. The speech recognition may be activated by turning on the food processor.

Claims

1. An electrically operated food processor (1) comprising:

(a) a mixing bowl (4);

(b) a mixer (5) in the mixing bowl (4);

(c) an acoustic transducer (19);

(d) a microcontroller comprising a speech recognition software; and

(e) an optical system which checks whether a person is located directly in front of and faces the food processor;

wherein speech recognition (E) causes the food processor (1) to carry out a routine task; and

wherein the food processor follows a speech instruction only when the speech instruction is given by the person and the person is located directly in front of and faces the food processor.

2. The food processor according to claim 1, wherein the speech recognition (E) is activated by turning on the food processor (1).

3. The food processor according to claim 1, wherein the speech recognition (E) can only be deactivated by turning off the food processor (1).

4. The food processor according claim 1, wherein the speech recognition (E) only starts or releases execution of a routine task if a signal word has been detected.

5. The food processor according to claim 1, wherein a heating of the mixing bowl and/or a running of the mixer (5) can be carried out only when the speed (C1), the temperature (C2) and the duration (C3) are provided or are accepted in response to a corresponding suggestion from the food processor (1).

6. The food processor according to claim 1, wherein the optical system is embodied to carry out a recognition in terms of a lip-reading.

7. The food processor according to claim 1, wherein, as a result of the optical recognition, the optical recognition is embodied to be compared with the speech recognition to increase the recognition rate.
