Abstract: Disclosed herein are speech therapeutic devices and methods. In one aspect, the speech therapeutic device includes audio input circuitry, signal processing circuitry, and stimulus circuitry. In certain embodiments, the audio input circuitry is configured to provide an input signal that is indicative of speech provided by a user and the signal processing circuitry is configured to utilize a reconfigurable rule that includes a condition, receive the input signal, process the input signal using the reconfigurable rule, and provide an alert signal responsive to attainment of the condition. The stimulus circuitry is configured to receive the alert signal and provide a stimulus to the user. The signal processing circuitry is additionally configured to (i) receive the reconfigurable rule from a communication network, and/or (ii) generate a record indicative of the alert signal, store the record in a memory, and send the record to a communication network.

Abstract: Systems, methods, and apparatuses to restore degraded speech via a modified diffusion model are described. An exemplary system is specially configured to train a diffusion-based vocoder containing an upsampler, based on pairing original speech x and degraded speech mel-spectrum mT samples; train a deep convoluted neural network (CNN) upsampler based on a mean absolute error loss to match the estimated original speech {circumflex over (x)}′ outputted by the diffusion-based vocoder by extracting the upsampler, generating a reference conditioner, and generating a weighted altered conditioner cTn′. The system further optimizes speech quality to invert non-linear transformation and estimate lost data by feeding the degraded mel-spectrum mT through the CNN upsampler and feeding the degraded mel-spectrum mT through the diffusion-based vocoder. The system then generates estimated original speech {circumflex over (x)}′ based on the corresponding degraded speech mel-spectrum mT. Other related embodiments are described.

Abstract: Systems and methods use patient speech samples as inputs, use subjective multi-point ratings by speech-language pathologists of multiple perceptual dimensions of patient speech samples as further inputs, and extract laboratory-implemented features from the patient speech samples. A predictive software model learns the relationship between speech acoustics and the subjective ratings of such speech obtained from speech-language pathologists, and is configured to apply this information to evaluate new speech samples. Outputs may include objective evaluation of the plurality of perceptual dimensions for new speech samples and/or evaluation of disease onset, disease progression, or disease treatment efficacy for a condition involving dysarthria as a symptom, utilizing the new speech samples.

Abstract: Speech analysis devices and methods for identifying migraine attacks are provided. Migraine sufferers can experience changes in speech patterns both during a migraine attack and in a pre-attack phase (e.g., a time period before the migraine attack can be recognized by the migraine sufferer). Embodiments identify or predict migraine attacks during the pre-attack phase and/or the attack phase (such as early stages of a migraine attack) by comparing speech features from one or more speech samples provided by a user against baseline data. The speech features are indicative and/or predictive of migraine onset, and can be personalized to a user and/or based on normative data.

Abstract: Disclosed herein are systems and methods for evaluating or analyzing cognitive function or impairment using speech analysis. In some implementations the evaluation of cognitive function comprises a predicted future cognitive function or change in cognitive function. In some implementations the cognitive function is evaluated using a panel or speech features such as a metric of semantic relevance, MATTR, and other relevant features. In another aspect, a machine learning predictive model for evaluating cognitive function based on speech, comprising: receiving input signal comprising speech audio for a plurality of subjects, to detect one or more metrics of speech identifying classifications corresponding to cognitive function and training a model using machine learning based on a training data set comprising the one or more metrics of speech and the classifications identified in the speech audio, thereby generating a machine learning predictive model configured to generate an evaluation of cognitive function based on speech.
