Abstract: A method includes receiving, by an electronic device, sensor data during a spirometry test of a user, the sensor data comprising audio data of the user, image data of a face of the user, and distance data of a distance from the face of the user. The method also includes obtaining, by the electronic device, at least one measured parameter associated with the spirometry test that is determined using at least one of the audio data, the image data, or the distance data, wherein the at least one measured parameter is correlated with an amount of air volume exchange or an amount of exhalation force by the user during the spirometry test. The method further includes providing, by the electronic device, real time feedback during the spirometry test, the real time feedback based on the at least one measured parameter, the real time feedback indicating whether or not the user is performing the spirometry test correctly.

Abstract: Device-invariant, frequency-domain signal processing with machine learning includes retrieving with a host device a device-specific alien dataset corresponding to an alien device. The device-specific alien dataset is retrieved from a remote data storage device communicatively coupled with the host device. A plurality of frequency-domain features are extracted from the device-specific alien dataset and a machine learning model is trained using the plurality of frequency-domain features. The host device extracts frequency-domain features from signals generated by sensors operatively coupled with the host device. Real-time frequency bin adaptation of the frequency-domain features extracted by the host device is performed. Based on the frequency-domain features extracted by the host device, as adapted, an inference is performed using the machine learning model.

Abstract: Pulmonary assessment based on speech can include identifying one or more audio features and speech patterns of a user's speech. A cognitive burden associated with the user's speech can be determined. A pulmonary condition of the user can be determined based on predetermined correlations between the one or more audio features and speech patterns of the user's speech, the cognitive burden, and a respiratory airway condition

Abstract: A method for pulmonary condition monitoring includes selecting a phrase from an utterance of a user of an electronic device, wherein the phrase matches an entry of multiple phrases. At least one speech feature that is associated with one or more pulmonary conditions within the phrase is identified. A pulmonary condition is determined based on analysis of the at least one speech feature.

Abstract: A method includes identifying, by an electronic device, one or more segments within a first audio recording that includes one or more non-speech segments and one or more speech segments. The method also includes generating, by the electronic device, one or more synthetic speech segments that include natural speech audio characteristics and that preserve one or more non-private features of the one or more speech segments. The method also includes generating, by the electronic device, an obfuscated audio recording by replacing the one or more speech segments with the one or more synthetic speech segments while maintaining the one or more non-speech segments, wherein the one or more synthetic speech segments prevent recognition of some content of the obfuscated audio recording.

Abstract: In one embodiment, a method includes accessing a video of a user's face. The method further includes accessing, for each image frame in the video, (1) one or more facial landmarks determined by a facial landmark detection (FLD) model and (2) a corresponding determined position in the image for each facial landmark. The method further includes determining, based on the one or more facial landmarks and corresponding positions, a motion of the user's face in the captured video; extracting, from the determined motion of the user's face, a corrected motion signal of the user's face; adjusting, based on the extracted corrected motion signal of the user's face, the positions of one or more facial landmarks in the image frames; and determining, based at least in part on the adjusted positions of the facial landmarks in the sequential images of the video, one or more vital signs of the user.

Abstract: In one embodiment, a method includes accessing a sequence of images of a portion of a person's skin illuminated by ambient light and determining, from at least one of the images, a plurality of microregions in the portion of the person's skin. The method further includes determining, based on a similarity between particular microregions of the plurality of microregions, one or more regions of interest of the person's skin; determining, for each of the regions of interest, a remote photoplethysmogram (rPPG) signal based on the sequence of images; and determining, based on one or more of the rPPG signals, an estimate of an oxygen saturation in the person's blood.

Abstract: Early detection of infectious respiratory diseases includes monitoring, during a predetermined time interval, electronic communications generated by network-connected portable devices, each portable device used by one of a plurality of users. The electronic communications are processed by extracting from each electronic communication biomarkers obtained by processing signals captured by the portable devices, the signals generated in response to sensor-detected respiratory activity of the portable device users. Clusters of users are generated based on the biomarkers and are conditioned based on pre-condition data extracted from the electronic communications, the pre-condition data corresponding to users determined to have pre-existing health conditions. Based on context data extracted from the electronic communications, user co-locations and pre-symptomatic biomarker variation co-occurrences are determined for users who exhibit pre-symptomatic biomarker variations associated with an infectious respiratory disease. An outbreak of the infectious respiratory disease is predicted along with the likelihood of infection for individuals based on the user co-locations and pre-symptomatic biomarker variation co-occurrences.
