Muting machine speech using audio watermarking

研究成果: Conference contribution

抄録

Spoken dialog systems have become popular and are used in a home environment, such as smart speakers. A problem will occur when two or more smart speakers are in the same environment, in which a dialog system misdetects the other dialog systems voice as a users voice. In this paper, a method to mute synthesized speech is proposed to prevent a speech recognizer from recognizing speech uttered by a machine. The audio watermark technique is used to indicate that a machine utters the speech, and the speech recognizer attenuates the observed speech if it contains the watermark. The watermark is embedded in high frequency so that humans cannot perceive the watermark and the watermark is robustly extracted. From the experimental result, we found that the proposed method robustly determine the existence of the watermark when the SNR is no less than 0 dB.
