Title:
DIGITAL-WATERMARK EMBEDDING DEVICE, DIGITAL-WATERMARK EMBEDDING METHOD, AND DIGITAL-WATERMARK EMBEDDING PROGRAM
Document Type and Number:
WIPO Patent Application WO/2014/199450
Kind Code:
A1
Abstract:
This digital-watermark embedding device is provided with the following: a synthesized-speech generation unit that, in accordance with inputted text, outputs synthesized speech and time information for the phonemes in said synthesized speech; an inference unit that uses inference to determine whether or not the inputted text contains latent-risk expressions, and if so, outputs latent-risk segments that were determined to contain such latent-risk expressions; an embedding control unit that, by associating the latent-risk segments with the abovementioned time information, determines and outputs embedding times at which to embed a digital watermark into the synthesized speech; and an embedding unit that embeds a digital watermark into the synthesized speech in a specific frequency band at the times specified by the aforementioned embedding times.
