摘要
The application relates to devices and methods for assessing cognitive impairment and/or speech motor impairment in a subject. The method comprises analysing a voice recording from a word- reading test obtained from the subject 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 associated with the recording. Determining the correct number of words in the recording may comprise computing one or more Mel-frequency cepstral coefficients (MFCCs) 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. The devices and methods find use in the diagnosis and monitoring of diseases or disorders such as neurological disorders.
