Abstract
Methods and processors for detecting a synthetic audio signal is disclosed. The method comprising: acquiring a candidate audio signal; generating a spectrogram representation of the candidate audio signal, the spectrogram representation comprising values for respective frequency-time pairs; generating a frequency-based combined patch using the spectrogram, a given combined value in the frequency-based combined patch being a combination of values from the spectrogram sharing a same frequency coordinate and different time coordinates; classifying the candidate audio signal as the synthetic audio signal using the frequency-based combined patch.

A method for detecting a synthetic audio signal, the method executable by a processor, the method comprising:
- acquiring a candidate audio signal;
- generating a spectrogram representation of the candidate audio signal, the spectrogram representation comprising values for respective frequency-time pairs;
- generating a frequency-based combined patch using the spectrogram,
- a given combined value in the frequency-based combined patch being a combination of values from the spectrogram sharing a same frequency coordinate and different time coordinates;
- classifying the candidate audio signal as the synthetic audio signal using the frequency-based combined patch.
A processor for detecting a synthetic audio signal, the processor configured to:
- acquire a candidate audio signal;
- generate a spectrogram representation of the candidate audio signal, the spectrogram representation comprising values for respective frequency-time pairs;
- generate a frequency-based combined patch using the spectrogram,
- a given combined value in the frequency-based combined patch being a combination of values from the spectrogram sharing a same frequency coordinate and different time coordinates;
- classify the candidate audio signal as the synthetic audio signal using the frequency-based combined patch.
A non-transitory computer-readable medium comprising executable instructions which, when executed by at least one processor, cause the at least one processor to carry out steps of a method for detecting a synthetic audio signal, the method comprising:
- acquiring a candidate audio signal;
- generating a spectrogram representation of the candidate audio signal, the spectrogram representation comprising values for respective frequency-time pairs;
- generating a frequency-based combined patch using the spectrogram,
- a given combined value in the frequency-based combined patch being a combination of values from the spectrogram sharing a same frequency coordinate and different time coordinates;
