Claim 11:
12. The apparatus according to claim 1,
wherein the apparatus comprises a user interface, wherein the user interface is configured to provide means for a user to select a processing rule out of a group of processing rules comprising at least two of a first processing rule and a second processing rule and a third processing rule and a fourth processing rule and a fifth processing rule and a sixth processing rule and a seventh processing rule;
wherein the processor is configured to process the audio input portion according to the processing rule selected by the user;
wherein according to the first processing rule, the processor is configured to generate the processed audio recording, such that the processed audio recording does not comprise the audio input portion;
wherein according to the second processing rule, the processor is configured to modify the audio input portion to obtain the modified audio portion such that the speech in the modified audio portion is non-understandable;
wherein according to the third processing rule, the processor is configured to modify the audio input portion to obtain the modified audio portion such that the speech is filtered out from the audio input portion;
wherein according to the fourth processing rule, the processor is configured to modify the audio input portion to obtain the modified audio portion such that the speech in the modified audio portion remains understandable, but such that it is no longer possible to identify a speaker of the speech by analyzing the modified audio portion;
wherein, according to the fifth processing rule being the particular processing rule, the processor is configured to generate the processed audio recording by employing said automatic speech recognition and/or said speaker identification, such that, if the speech originates from said previously identified speakers or from said speakers that have trained the apparatus, the speech remains understandable in the modified audio portion; and otherwise, the processed audio recording does not comprise the audio input portion, or the modified audio portion is generated using said voice filter, such that only speech from the previously identified speakers or from the speakers that have trained the apparatus is understandable;
wherein according to the sixth processing rule, the processor is configured to generate the processed audio recording by employing automatic speech recognition such that the processed audio recording comprises the audio input portion only if the speech in the audio input portion comprises predefined first key words; and/or the processor is configured to generate the processed audio recording by employing automatic speech recognition such that the processed audio recording comprises the audio input portion only if the speech in the audio input portion does not comprise predefined second key words; and/or the processor is configured to generate the processed audio recording by employing automatic speech recognition such that the processed audio recording comprises the audio input portion only if the speech in the audio input portion does not comprise names; and
wherein according to the seventh processing rule, the processor is configured to determine a value indicating a degree of understandability of the speech in the audio input portion, and the processor is configured to generate the processed audio recording such that the processed audio recording comprises the audio input portion depending on said value that indicates the degree of understandability.
