Summary of the acoustic properties of auditory stimuli.
| Stimulus | Mandarin syllables | Harmonic sounds | ||||
|---|---|---|---|---|---|---|
| Pitch Contour (Hz) | Duration (ms) | VOT (ms) | Pitch Contour (Hz) | Duration Vowel (ms) | VOT (consonant) | |
| Standard | 164.8–164.8 | 260 | CH (105 ms) | 164.8–164.8 | 260 | 0 |
| Pitch large | 164.8–185.0 | – | – | 164.8–185.0 | – | – |
| Pitch small | 164.8–168.7 | – | – | 164.8–169.6 | – | – |
| Duration large | – | 140 | – | – | 140 | – |
| Duration small | – | 220 | – | – | 220 | – |
| VOT large | – | – | ZH (50 ms) | – | – | 60 |
| VOT small | – | – | CH (60 ms) | – | – | 30 |
*VOT for harmonic sounds is defined as the time set to zero from the beginning of the stimuli. For Syllables it represents the length of the first part of the consonant used. The dash (−) represents the same value as the standard.
