Abstract
Disclosed are systems and methods including software processes executed by a server for obtaining, by a computer, an audio signal including synthetic speech, extracting, by the computer, metadata from a watermark of the audio signal by applying a set of keys associated with a plurality of text-to-speech (TTS) services to the audio signal, the metadata indicating an origin of the synthetic speech in the audio signal, and generating, by the computer, based on the extracted metadata, a notification indicating that the audio signal includes the synthetic speech.
Claims20
A computer-implemented method comprising:
- obtaining, by a computer, an audio signal including synthetic speech;
- extracting, by the computer, metadata from a watermark of the audio signal by applying a set of keys associated with a plurality of text-to-speech (TTS) services to the audio signal, the metadata indicating an origin of the synthetic speech in the audio signal;
- and
- generating, by the computer, based on the metadata as extracted from the watermark, a notification indicating that the audio signal includes the synthetic speech.
A system comprising:
- a computing device comprising at least one processor, configured to:
- obtain an audio signal including synthetic speech;
- extract metadata from a watermark of the audio signal by applying a set of keys associated with a plurality of text-to-speech (TTS) services to the audio signal, the metadata indicating an origin of the synthetic speech in the audio signal;
- and
- generate, based on the metadata as extracted from the watermark, a notification indicating that the audio signal includes the synthetic speech.
