“…One method that has received significant attention is the neural network technique. The signal is windowed and then multiple time-varying features are calculated before being fed into the neural network [24, 25, 26, 27]. After sufficient training this network should be able to differentiate between periods of time where swallowing activity is present or absent based on the values of the inputs [24, 25, 26, 27].…”

“…The signal is windowed and then multiple time-varying features are calculated before being fed into the neural network [24, 25, 26, 27]. After sufficient training this network should be able to differentiate between periods of time where swallowing activity is present or absent based on the values of the inputs [24, 25, 26, 27]. However, it is very computationally intensive and researchers are still debating what features are valid inputs to use for the purposes of segmentation [24, 25, 26, 27].…”

“…While some place it as low as 0.1 Hz in order to maintain a “pure” signal [21], [49], [51], [65], [66], [83], [86], [90], others place it as high as 30 Hz or more in order to eliminate motion artifacts and other low frequency noise [39], [42], [44], [60]–[62], [69]. Since similar bandlimits have yet to be identified for swallowing sounds, studies which use a microphone simply limit the recorded signal to either the human audible range [21], [32], [33], [37], [40], [46], [48], [67], [76]–[78], [86], [89], [95], [97]–[100], [102], [103], [110], [112]–[116] or the range of common stethoscopes used in bedside assessments [13], [22], [28], [39], [56], [69], [73], [88], [91], [92]. Typically, this bare minimum amount of signal processing has traditionally been done for one of two reasons.…”

“…The basis of this research involves sound classification techniques. Several techniques have been proposed to solve the problem of sound classification [17–25]. Most of these sound classification methods consist of two processing steps: feature extraction and classification.…”
