Stable Vowel Corpus (SVC): a benchmark for spectral stability analyses

This dataset comprises 4,860 synthesized CVC-like sequences generated using Praat's articulatory synthesizer (Boersma, 1998; Boersma & Weenink, 2021). The duration and location of the spectrally stable portion of the vowel within these CVC-like sequences were randomly varied. Each corresponding .wav file is labeled with the following format: Stimulus ID_TsV_TeV_C1_V_C2_speaker.wav e.g. 1000_0.2197529077064245_0.2906336685046843p_a_d_female.wav Here's the breakdown of the naming convention: Stimulus ID: A unique identifier for each stimulus. TsV: The timecode of the start of the stable portion of the vowel. TeV: The timecode of the end of the stable portion of the vowel. C1: The first consonant category. V: The vowel category. C2: The second consonant category. Speaker: The type of artificial speaker used for the synthesis.
