Abstract: The present invention relates toamethod forspeech watermarking inspeaker verification,comprising the steps of: embedding watermark data into speech signal at a transmitter; and extracting watermark data from the speech signal at a receiver;characterisedby the steps of: selecting frameshavingleast speaker-specific information fromthe speech signal to carry watermark data; detecting voice activity to detect presence or absence of speaker's voice in the speech signal;and embedding watermark data into the selected frames of the speech signal according to thepresence or absence of the speaker's voice.
