Claim 16:
17. The apparatus according to claim 15,
wherein the processor is configured to store the audio input portion in the memory, and
wherein the processor is configured to process the audio input portion according to a first processing rule or according to a second processing rule or according to a third processing rule or according to a fourth processing rule or according to a fifth processing rule or according to a sixth processing rule or according to a seventh processing rule; and
wherein the processor is configured to replace the audio input portion in the memory by the modified audio portion or to remove the audio input portion from the memory without replacement depending on the processing;
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, the processor is configured to generate the processed audio recording by employing speaker identification and/or automatic speech recognition and/or voice filtering, such that, if the speech originates from previously identified speakers or from 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 a voice filter, such that only speech from the previously identified speakers or from the speakers that have trained the apparatus is understandable; or the processor is configured to generate the processed audio recording by employing speaker identification and/or automatic speech recognition and/or voice filtering, such that, if the speech originates from previously identified speakers or from speakers that have trained the apparatus, the processed audio recording does not comprise the audio input portion, or the modified audio portion is generated using a voice filter, such that the speech from the previously identified speakers or from the speakers that have trained the apparatus is not understandable; and otherwise the speech remains understandable in the modified audio portion;
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.
