Zusammenfassung:The present invention relates to a method for speech watermarking for speaker 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; characterised by the steps of: selecting frames having least speaker-specific information from the speech signal to carry watermark data; detecting voice activity to categorize the selected frames into voice and non-voice frames to detect presence or absence of speaker's voice in the speech signal; and embedding watermark data regarding to speech characteristics of voice and non-voice frames into the selected frames of the speech signal.
