Automatic call categorization and screening

A computer-implemented method to automatically answer a call, the method comprising:

• receiving, at a client device, a call from a caller device;
• determining, by the client device, based on an identifier associated with the call, whether the call matches auto answer criteria;
• in response to determining that the call matches the auto answer criteria, answering the call, by the client device, without user input and without alerting a user of the client device;
• and
• after answering the call,
• generating, by the client device, using a trained machine-learning model, a call embedding for the call based on received audio of the call, wherein the call embedding is a numerical representation of the call;
• comparing, by the client device, the call embedding with spam embeddings to determine whether the call is a spam call;
• and
• in response to determining that the call is a spam call, terminating the call.

A computing device comprising:

• a processor;
• and
• a memory coupled to the processor, with instructions stored thereon that, when executed by the processor, cause the processor to perform operations comprising:
• receiving a call from a caller device;
• determining, based on an identifier associated with the call, whether the call matches auto answer criteria;
• in response to determining that the call matches the auto answer criteria, answering the call without user input and without alerting a user of the computing device;
• and
• after answering the call,
• generating using a trained machine-learning model, a call embedding for the call based on received audio of the call, wherein the call embedding is a numerical representation of the call;
• comparing the call embedding with spam embeddings to determine whether the call is a spam call;
• and
• in response to determining that the call is a spam call, terminating the call.
