Before … WebPraat’s default pitch settings (75-600 Hz [5]) could lead to chance high-frequency periodicity being interpreted as voicing. This was remedied by lowering the pitch ceiling to 300 Hz. However, the tokens were not manually segmented for voicing duration and so the VR measure’s accuracy as a gradient measure could not be tested.
