Mandarin speech‐based early detection of SCD: a feature‐fusion residual network method

open access: yesAlzheimer's &Dementia, Volume 22, Issue 5, May 2026.
Abstract INTRODUCTION Alzheimer's disease (AD) poses a global health challenge. Early intervention during the stage of subjective cognitive decline (SCD) – a potential window for delaying disease progression – is crucial. This study aims to assess an exploratory speech‐based model for rapid SCD screening.

Spoken English Assisted Training Model Based on Multifeature Parameters and Dynamic Time Warping Algorithm

open access: yesEngineering Reports, Volume 8, Issue 5, May 2026.
Flow chart of the base sound trace extraction of speech. ABSTRACT With the acceleration of internationalization, the deficiency of traditional English classroom in English spoken teaching is becoming more obvious, especially the lack of effectiveness and immediate feedback. Therefore, a spoken English assisted training model is proposed.

Automated classification of vowel category and speaker type in the high-frequency spectrum

open access: yesAudiology Research, 2016
The high-frequency region of vowel signals (above the third formant or F3) has received little research attention. Recent evidence, however, has documented the perceptual utility of high-frequency information in the speech signal above the traditional ...

A dual-stream CNN-based ConvMixer for durian ripeness classification using magnitude and phase features from knocking sounds

open access: yesResults in Engineering
Knocking-sound analysis provides a non-destructive method for assessing durian ripeness; however, most convolutional neural network methods mainly emphasize magnitude information while disregarding phase information that reflects the overall signal ...
