Abstract: A computer-based method for screening unknown subjects for COVID-19, including steps of recording at least one voice clip from a screened subject, pre-processing the screened subject voice clip, computing a spectrogram of the pre-processed screened subject voice clip, extracting a feature vector from said screened subject spectrogram, applying a machine learning classifier of a COVID-19 vocal biomarker on the extracted screened subject feature vector thereby receiving a COVID-19 vocal biomarker value, and outputting that the screened subject is COVID-19 positive or COVID-19 negative, based on the COVID-19 vocal biomarker value. The step of extracting the feature vector employs a pre-trained deep convolutional neural network.

Abstract: A system and method for monitoring disease, such as lung disease via a communication device of a user is disclosed. The system and method may include a communication device, such as a smartphone, a laptop, a smartwatch and the like, and may including a memory and a processor configured to: obtain information related to a user's medical condition; determine, while the user is using the communication device, respiratory characteristics of the user based on a recording of a respiration of the user; and determine a progress of a disease of the user based on the user's medical condition and based on comparing the characteristics to a reference set of characteristics. The reference set of characteristics may be created, by the processor, by obtaining signals related to the user's breathing while the user uses the communication device.

Abstract: A system and method for monitoring and determining a medical condition of a user, via a communication device of the user is disclosed. The system and a method according to some embodiments, may comprise a memory and a processor, the processor may be configured to receive an audio signal related to a user's speech, and determine a progress of a disease of the user based on comparing the audio signal to a reference audio signal. According to some embodiments, the memory and processor may be included in a mobile communication device operated by the user, the reference audio signal may be generated based on recording normal speech of the user e.g. during telephone calls.
