Abstract
This disclosure describes systems, methods, and devices related to automatic personal identifiable information (PII) removal. A system may detect a sound signal received from a vicinity of a machine during the operation of the machine. The system may perform speech detection to detect a segment of the sound signal that comprises a speech signal. The system may modify the sound signal at the segment of the sound signal by performing a segment replacement mechanism. The system may generate a filtered sound signal to be used for monitoring the operation of the machine.
Claims20
A system, comprising:
- at least one memory that stores computer-executable instructions;
- and at least one processor configured to access the at least one memory and execute the computer-executable instructions to:
- detect a sound signal received from a vicinity of a machine during operation of the machine;
- perform speech detection to detect a segment of the sound signal that comprises a speech signal;
- modify the sound signal at the segment of the sound signal by performing a segment replacement mechanism, including filtering out the speech signal from the segment of the sound signal using a reference signal;
- and
- generate a filtered sound signal to be used for monitoring the operation of the machine, wherein monitoring the operation of the machine includes monitoring the sound signal and the filtered sound signal for indications the machine is operating atypically.
A non-transitory computer-readable medium storing computer-executable instructions which when executed by one or more processors result in performing operations comprising:
- detecting a sound signal received from a vicinity of a machine during operation of the machine;
- performing speech detection to detect a segment of the sound signal that comprises a speech signal;
- modifying the sound signal at the segment of the sound signal by performing a segment replacement mechanism, including filtering out the speech signal from the segment of the sound signal using a reference signal;
- and
- generating a filtered sound signal to be used for monitoring the operation of the machine.
A method comprising:
- detecting, by one or more processors, a sound signal received from a vicinity of a machine during operation of the machine;
- performing speech detection to detect a segment of the sound signal that comprises a speech signal;
- modifying the sound signal at the segment of the sound signal by performing a segment replacement mechanism, including filtering out the speech signal from the segment of the sound signal using a reference signal;
- and
- generating a filtered sound signal to be used for monitoring the operation of the machine.
