  • Publication number: 20230066915
    Abstract: In some implementations, a system may receive an audio stream associated with a call between a user and an agent. The system may analyze the audio stream to identify a trigger associated with the type of information. The system may monitor, based on identifying the trigger in a first section of the audio stream, a second section of the audio stream for audio content that identifies user information associated with the user. The system may identify a subsection of the second section that includes the audio content, wherein the subsection is identified based on a characteristic of the audio content and the type of information. The system may alter an audio characteristic of the subsection to prevent the agent from receiving the user information via the audio stream.

  • Publication number: 20230066847
    Abstract: In some implementations, a system may receive an audio stream associated with a call between a user and an agent. The system may process, by the device and using a speech alteration model, speech from a first channel of the audio stream to alter the speech from having a first speech characteristic to having a second speech characteristic, wherein the speech alteration model is trained based on reference audio data associated with the first speech characteristic and the second speech characteristic and based on reference speech data associated with the first speech characteristic and the second speech characteristic. The system may extract the speech from the first channel that has the first speech characteristic. The system may provide, within a second channel of the audio stream, altered speech that corresponds to the speech and that has the first speech characteristic.

  • Publication number: 20220334503
    Abstract: A method for determining lithographic matching performance includes obtaining first monitoring data from recurrent monitoring for stability control for an available EUV scanner. For a DUV scanner, second monitoring data is similarly obtained from recurrent monitoring for stability control. The EUV first monitoring data are in a first layout. The DUV second monitoring data are in a second layout. A cross-platform overlay matching performance between the first lithographic apparatus and the second lithographic apparatus is determined based on the first monitoring data and the second monitoring data. This is done by reconstructing the first and/or second monitoring data into a common layout to allow comparison of the first and second monitoring data.

  • Patent number: 11281110
    Abstract: A method of determining a sampling control scheme and/or a processing control scheme for substrates processed by a device. The method uses a fingerprint model and an evolution model to generate the control scheme. The fingerprint model is based on fingerprint data for a processing parameter of at least one substrate processed by a device, and the evolution model represents variation of the fingerprint data over time. The fingerprint model and the evolution model are analyzed and a sampling and/or processing control scheme is generated using the analysis. The sampling control scheme provides an indication for where and when to take measurements on substrates processed by the device. The processing control scheme provides an indication for how to control the processing of the substrate. Also, there is provided a method of determining which of multiple devices contributed to a fingerprint of a processing parameter.
