  • Patent number: 10638252
    Abstract: An audio assembly includes a microphone assembly, a controller, and a speaker assembly. The microphone assembly detects audio signals. The detected audio signals originate from audio sources located within a local area. Each audio source is associated with a respective beamforming filter. The controller determines beamformed data using the beamforming filters associated with each audio source and a relative contribution of each of the audio sources using the beamformed data. The controller generates updated beamforming filters for each of the audio sources based in part on the relative acoustic contribution of the audio source, a current location of the audio source, and a transfer function associated with audio signals produced by the audio source. The controller generates updated beamformed data using the updated beamforming filters and performs an action (e.g., via the speaker assembly) based in part on the updated beamformed data.

  • Patent number: 10614165
    Abstract: An architecture and processes enable computer learning and developing an understanding of arbitrary natural language text through collaboration with humans in the context of joint problem solving. The architecture ingests the text and then syntactically and semantically processes the text to infer an initial understanding of the text. The initial understanding is captured in a story model of semantic and frame structures. The story model is then tested through computer generated questions that are posed to humans through interactive dialog sessions. The knowledge gleaned from the humans is used to update the story model as well as the computing system's current world model of understanding. The process is repeated for multiple stories over time, enabling the computing system to grow in knowledge and thereby understand stories of increasingly higher reading comprehension levels.

  • Patent number: 10586532
    Abstract: The disclosed system addresses a technical problem tied to computer technology and arising in the realm of computer memory capacity, namely the technical problem of providing a flexible response dialogue system that can be utilised for a variety of different types of dialogue without requiring the system to be specifically trained for each situation. This therefore avoids the need for large amounts of labelled training data for each type of dialogue (each potential conversation flow or subject area for the conversation). The disclosed system solves this technical problem by using semantic similarity to match a user's input to one of a set of predefined inputs (predefined user responses). Various mechanisms are implemented to provide disambiguation in the event of multiple potential matches for the input. By using semantic similarity, the user's response in unconstrained. This therefore provides a user interface that is more user-friendly.

    Abstract: An FFT processor applies the fast Fourier transform to each frame of an input signal and generates frequency domain data. A first spectrum calculator calculates the amplitude spectrum of the input signal for the individual frequency components based on the frequency domain data. A dispersion index calculator calculates a dispersion index indicating the level of dispersion of the amplitude spectrum of the input signal in the latest frames. A noise index calculator calculates a noise index indicating the level of noise contained in the input signal. A second spectrum calculator calculates the amplitude spectrum of the noise for the individual frequency components. A gain calculator calculates a spectral gain for suppressing the noise for the individual frequency components. An IFFT processor applies the inverse fast Fourier transform to the frequency domain data after multiplication by the spectral gain at a multiplier, and generates a signal to be output.

  • Patent number: 10418037
    Abstract: A sampled speech data sequence contains words spoken by a speaker. A sequence of feature vectors is generated characterizing spectral distribution of sampled speech data. A textual transcript of the words spoken by the speaker is obtained. Data structures of a universal background model of a Gaussian mixture model (UBM-GMM) and of an Enrolled speaker Gaussian mixture model (ENR-GMM) are adapted responsive to the textual transcript, to generate an adapted UBM-GMM and an adapted ENR-GMM, respectively. An enrolled speaker probability is generated based on the sequence of feature vectors and the adapted ENR-GMM, and a universal speaker probability is generated based on the sequence of feature vectors and the adapted UBM-GMM. A speaker verification indication of whether the speaker is an enrolled speaker is generated by comparing the enrolled speaker probability to the universal speaker probability.
