    Abstract: A method for text to speech conversion and for adjusting a corpus. The method includes a text analysis step for parsing the text to obtain descriptive prosody annotations of the text based on a TTS model generated from a first corpus, a prosody parameter prediction step for predicting the prosody parameter of the text according to the result of the text analysis step, a speech synthesis step for synthesizing speech of the text based on the prosody parameter of the text, adjusting according to a target speech speed for the synthesized speech when necessary.

    Abstract: Systems and methods configured for recoding an odd integer and elliptic curve point multiplication are disclosed, having general utility and also specific application to elliptic curve point multiplication and cryptosystems. In one implementation, the recoding is performed by converting an odd integer k into a binary representation. The binary representation could be, for example, coefficients for powers of two representing the odd integer. The binary representation is then configured as comb bit-columns, wherein every bit-column is a signed odd integer. Another implementation applies this recoding method and discloses a variation of comb methods that computes elliptic curve point multiplication more efficiently and with less saved points than known comb methods. The disclosed point multiplication methods are then modified to be Simple Power Analysis (SPA)-resistant.

    Abstract: A digital watermarking method performs tonal detection on a signal (e.g., audio) to identify tonal and non-tonal components. These components are analyzed to compute appropriate weighting of a digital watermark for the tonal and non-tonal components. This tonal detection method is also used in recovering the watermark. A decoding method performs tonal detection on a watermarked signal, computes weights for tonal and non-tonal components, and recovers the embedded watermark using the weights. The same or different watermark embedding schemes may be used to embed digital watermarks in the tonal and non-tonal components. Tonal analysis is used in conjunction with frequency and temporal shaping to adapt the digital watermark to the signal in which it is embedded.
