Additional Data

Audio S1-S96
Audio S1 â€" S48: Synthesized set of speech stimuli that independently varies intonation contour, phonetic content, and speaker. Each individual .wav file is named snX_stY_spZ.wav, where X is 1- 4, Y is 1-4, and Z is 1-3. X indicates the sentence condition (sentence number or sn). Y indicates the intonation contour (sentence type or st). Z indicates the speaker (speaker or sp). Audio S49 â€" S80: Set of non-speech stimuli that preserves intonational pitch contour but removes spectral content related to phonetic features. These stimuli also have varying amplitude contours corresponding to the sentence condition from the original set of speech stimuli. Each wav file is named purr_Z_stY_snX, where Z is either “femaleâ€� or “maleâ€�, Y indicates the intonation contour (1: Neutral, 2: Question, 3: Emphasis 1, 4: Emphasis 3), and X indicates which sentence condition the amplitude contour came from (1-4). These stimuli were played to 5/10 total participants. Audio S81 â€" S88: Set of non-speech stimuli that preserves intonational pitch contour, but removes spectral content related to phonetic features. These stimuli have flat amplitude contours. Each wav file is named purr_stretch_0_Z_stY, where Z is either “femaleâ€� or “maleâ€� and Y indicates the intonation contour (1: Neutral, 2: Question, 3: Emphasis 1, 4: Emphasis 3). These stimuli were played to 3/10 total participants. Audio S89 â€" S96: Missing fundamental stimuli that preserves intonational pitch contour. These stimuli are the combination of the fourth, fifth, and sixth harmonics of the fundamental frequency contour with pink noise added 0.25 before pitch contour onset to mask energy at the fundamental frequency that may be introduced at the level of the cochlea. Each wav file is named purr_missing_f0_noise_first_stretch_0_Z_stY, where Z is either “femaleâ€� or “maleâ€� and Y indicates the intonation contour (1: Neutral, 2: Question, 3: Emphasis 1, 4: Emphasis 3). These stimuli were played to 3/10 total participants.
