Automated Assessment of Cognitive and Speech Motor Impairment
Summary
USPTO published patent application US20260108202A1, filed 2025-12-08 under application number 19412712, for an automated method of assessing cognitive impairment and/or speech motor impairment. The method analyses voice recordings from word-reading tests by identifying segments corresponding to individual words or syllables, computing Mel-frequency cepstral coefficients, clustering vectors into n clusters, predicting word sequences, and performing sequence alignment to count correctly read words and measure speech rate. Inventors: Florian Lipsmeier, Martin Christian Strahm, Detlef Wolf, Yan-Ping Zhang Schaerer.

Abstract
The application relates to assessing cognitive impairment and/or speech motor impairment. The method comprises analysing a voice recording from a word-reading test by identifying a plurality of segments of the voice recording that correspond to single words or syllables and determining the number of correctly read words in the voice recording and/or the speech rate. Determining the correct number of words in the recording may comprise computing one or more Mel-frequency cepstral coefficients for the segments, clustering the resulting vectors of values into n clusters, wherein each cluster has n possible labels, predicting a sequence of words in the voice recording using the labels associated with the clustered vectors of values, performing a sequence alignment between the predicted sequence of words and the sequence of words used in the word reading test, selecting the labels that result in the best alignment and counting the number of matches in the alignment.
