Apparatus and method for processing an audio input recording to obtain a processed audio recording to address privacy issues

An apparatus for processing an audio input recording to obtain a processed audio recording, wherein the apparatus comprises:

• an input interface for receiving a plurality of audio input portions of the audio input recording, and
• a processor for processing a plurality of audio input portions of the audio input recording to obtain a processed audio recording,
• wherein the processor is configured to determine, whether or not an audio input portion of the plurality of audio input portions comprises speech,
• wherein, if the processor has detected that the audio input portion comprises speech, the processor is configured to generate the processed audio recording by modifying the audio input portion to obtain a modified audio portion, and by generating the processed audio recording such that the processed audio recording comprises the modified audio portion instead of the audio input portion,
• wherein, if the processor has detected that the audio input portion comprises speech and if the audio input portion shall be processed according to a particular processing rule, the processor is configured to generate the processed audio recording by employing automatic speech recognition and/or speaker identification, 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.
