Detecting synthetic sounds in call audio

A method for detecting synthetic audio in call audio, comprising:

• capturing, by a system, audio from a call between a calling device and a called device;
• filtering, by the system and based on one or more audio characteristics of the captured audio, the captured audio to generate a background audio layer;
• generating, by the system, an audio footprint that is a representation of sound in the background audio layer;
• determining, by the system, that the audio footprint includes a triggering sound footprint based on one or more audio characteristics of the audio footprint;
• detecting, by the system, synthetic sound based on the audio footprint and after determining that the audio footprint includes the triggering sound footprint,
• wherein the synthetic sound is indicative of a sound recording, and
• wherein the synthetic sound is detected based on at least one of:
• a first portion of the audio footprint sufficiently matching a second portion of the audio footprint, or
• comparing a portion of the audio footprint to a plurality of stored audio footprints based on a plurality of priority indicators corresponding to the plurality of stored audio footprints and the portion of the audio footprint sufficiently matching a stored audio footprint, wherein the stored audio footprint is not generated from the captured audio;
• and
• transmitting, by the system, a notification to one or more devices associated with the call based on detecting the synthetic sound.

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a system, cause the system to:
• capture audio from a call between a calling device and a called device;
• filter, based on one or more audio characteristics of the captured audio, the captured audio to generate a background audio layer;
• generate an audio footprint that is a representation of sound in the background audio layer;
• determine that the captured audio includes synthetic sound based on the audio footprint, wherein the synthetic sound is indicative of a sound recording, and
• wherein the synthetic sound is detected based on at least one of:
• a first portion of the audio footprint sufficiently matching a second portion of the audio footprint, or
• comparing a portion of the audio footprint to a plurality of stored audio footprints based on a plurality of priority indicators corresponding to the plurality of stored audio footprints and the portion of the audio footprint sufficiently matching a stored audio footprint, wherein the stored audio footprint is not generated from the captured audio;
• and
• transmit a notification to one or more devices associated with the call based on determining that the captured audio includes the synthetic sound.
