Abstract: An estimate of a fractional chirp rate of a signal may be computed by using multiple frequency representations of the signal. A first frequency representation may be computed using a first fractional chirp rate and a first score may be computed using the first frequency representation that indicates a match between the first fractional chirp rate and a fractional chirp rate of the signal. A second frequency representation may be computed using a second fractional chirp rate and a second score may be computed using the second frequency representation that indicates a match between the second fractional chirp rate and the fractional chirp rate of the signal. The fractional chirp rate of the signal may be estimated using the first score and the second score, for example, by selecting a fractional chirp rate corresponding to a highest score.

Abstract: The technology described in this document can be embodied in a computer-implemented method that includes obtaining a speech signal, and estimating a first set and a second set of segment boundaries using the speech signal.

The second segmentation process is different from the first segmentation process. The method also includes obtaining a model corresponding to a distribution of segment boundaries, computing a first score indicative of a degree of similarity between the model and the first set of segment boundaries, and computing a second score indicating a degree of similarity between the model and the second set of segment boundaries. The method further includes selecting a set of segment boundaries using the first score and the second score, and processing the speech signal using the selected set of segment boundaries.

Abstract: Input data may be classified using one or both of mutual information between segments and expected class scores. Input data to be classified may be segmented into an input sequence of segments. The input sequence of segments may be compared with a reference sequences of segments for a first class to generate a first class score indicating a similarity between the input data and the first class. The first class score may be computed by computing a probability mass function between input segments and reference segments and then computing a mutual information value from the probability mass function. The input data may then be classified using the first class score and/or class score for other classes. In some implementations, expected class scores may be used in making the classification decision.

Abstract: A sound absorbing game paddle containing a blade having a support structure and a filling. The support structure preferably defines adjoining cells of various shapes, including for example hexagonal and non-hexagonal cells. The filling preferably comprises one or more of a foam, a gel, a silicone or other polymer, and can fill some or all of the cells at any desired volume(s). Contemplated methods include a manufacturer building a version of a game paddle without a filling, and subsequently building another version of the same or similar paddle with a filling. Further contemplated methods include developing an improved game paddle with altered sound emissions by determining that an existing game paddle has undesirable peak amplitudes and frequencies of sounds emitted, and then designing an improved game paddle with a sound absorbing filling.

Abstract: An estimate of a pitch of a signal may be computed by using correlations of frequency portions of a frequency representation of the signal. An initial pitch estimate may be obtained and frequency portions of the frequency representation may be identified using multiples of the initial pitch estimate. Correlations of the frequency portions may be computed, and a score for the initial pitch estimate may be determined using the correlations. A second pitch estimate may be determined using the first score, and the process may be repeated.

Abstract: Features that may be computed from a harmonic signal include a fractional chirp rate, a pitch, and amplitudes of the harmonics. A fractional chirp rate may be estimated, for example, by computing scores corresponding to different fractional chirp rates and selecting a highest score. A first pitch may be computed from a frequency representation that is computed using the estimated fractional chirp rate, for example, by using peak-to-peak distances in the frequency distribution. A second pitch may be computed using the first pitch, and a frequency representation of the signal, for example, by using correlations of portions of the frequency representation. Amplitudes of harmonics of the signal may be determined using the estimated fractional chirp rate and second pitch. Any of the estimated fractional chirp rate, second pitch, and harmonic amplitudes may be used for further processing, such as speech recognition, speaker verification, speaker identification, or signal reconstruction.
