Patent number: 11887587Abstract: An apparatus for processing an audio input recording to obtain a processed audio recording according to an embodiment is provided. The apparatus comprises an input interface (110) for receiving a plurality of audio input portions of the audio input recording. Moreover, the apparatus comprises a processor (120) for processing a plurality of audio input portions of the audio input recording to obtain a processed audio recording. The processor (120) is configured to determine, whether or not an audio input portion of the plurality of audio input portions comprises speech. If the processor (120) has detected that the audio input portion comprises speech, the processor (120) 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.Type: GrantFiled: April 14, 2021Date of Patent: January 30, 2024Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Jan Rennies-Hochmuth, Danilo Hollosi, Christian Rollwage, Jens-Ekkehart Appell

Patent number: 11122157Abstract: A telecommunication device includes an audio signal transmission unit configured to receive an audio signal and to transmit the same to a further telecommunication device. The telecommunication device further includes a signaling unit configured to output a signaling when there is a concern that the audio signal is acoustically understandable for third parties or represents a disturbance for third parties. A further telecommunication device includes an audio signal receive unit configured to receive an audio signal from a further telecommunication device and to output the same acoustically, and a signaling unit configured to output a signaling when there is a concern that the output audio signal is acoustically understandable for third parties or represents a disturbance. The telecommunication devices may be interconnected in a system. Also described are corresponding methods for operation and a computer program.Type: GrantFiled: August 29, 2018Date of Patent: September 14, 2021Assignee: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Jens Ekkehart Appell, Jan Rennies-Hochmuth
