  • Patent number: 9553977
    Abstract: A system for automated adaptation and improvement of speaker authentication in a voice biometric system environment, comprising a speech sample collector, a target selector, a voice analyzer, a voice data modifier, and a call flow creator. The speech sample collector retrieves speech samples from a database of enrolled participants in a speaker authentication system. The target selector selects target users that will be used to test the speaker authentication system. The voice analyzer extracts a speech component data set from each of the speech samples. The call flow creator creates a plurality of call flows for testing the speaker authentication system, each call flow being either an impostor call flow or a legitimate call flow. The call flows created by the call flow creator are used to test the speaker authentication system.

  • Patent number: 9546924
    Abstract: Methods and devices for efficient encoding/decoding of a time segment of an audio signal. The methods comprise deriving an indicator, z, of the position in a frequency scale of a residual vector associated with the time segment of the audio signal, and deriving a measure, ?, related to the amount of structure of the residual vector. The methods further comprise determining whether a predefined criterion involving the measure ?, the indicator z and a predefined threshold ?, is fulfilled, which corresponds to estimating whether a change of sign of at least some of the non-zero coefficients of the residual vector would be audible after reconstruction of the audio signal time segment. The respective amplitude of the coefficients of the residual vector is encoded, and the signs of the coefficients of the residual vector are encoded only when it is determined that the criterion is fulfilled, and thus that a change of sign would be audible.

  • Patent number: 9502024
    Abstract: An automatic speech recognition (ASR) system includes a speech-responsive application and a recognition engine. The ASR system generates user prompts to elicit certain spoken inputs, and the speech-responsive application performs operations when the spoken inputs are recognized. The recognition engine compares sounds within an input audio signal with phones within an acoustic model, to identify candidate matching phones. A recognition confidence score is calculated for each candidate matching phone, and the confidence scores are used to help identify one or more likely sequences of matching phones that appear to match a word within the grammar of the speech-responsive application. The per-phone confidence scores are evaluated against predefined confidence score criteria (for example, identifying scores below a ‘low confidence’ threshold) and the results of the evaluation are used to influence subsequent selection of user prompts.

  • Patent number: 9471560
    Abstract: Various techniques for autocorrecting virtual keyboard input for various languages (e.g., Japanese, Chinese) are disclosed. In one aspect, a system or process receives a sequence of keyboard events representing keystrokes on a virtual keyboard. A hierarchical data structure is traversed according to the sequence of keyboard events to determine candidate words for the sequence of keyboard events. A word lattice is constructed using a language model, including deriving weights or paths in the word lattice based on candidate word statistics and data from a keyboard error model. The word lattice is searched to determine one or more candidate sentences comprising candidate words based on the path weights. Paths through the word lattice can be pruned (e.g., discarded) to reduce the size and search time of the word lattice.
