IDSViz is an interactive tool for exploring infant-directed speech (IDS) in English and Spanish. Browse vowel and consonant patterns, see how phonemes are realized phonetically in the IPA confusion matrix, and listen to audio clips of phonemes in context drawn from real recordings.
Plot vowels in formant space (F1/F2/F3/duration) and explore consonant variation by phonetic realization, preceding segment, or following segment.
View an IPA confusion matrix showing how phonemic categories map to their phonetic realizations in the English IDS dataset.
Search for any IPA phoneme and play back trimmed audio clips extracted from the source recordings, optionally with their neighboring sounds for context.
