Sound explorer

Browse all 9 consonants (× 3 vowel heights) freely — click any sound to hear it and see its diagram together. Use the row/column buttons to compare one axis at a time (e.g. Interrupted vs. Continuous vs. Gradual at a fixed locus, or Sharp vs. Acute vs. Mid vs. Grave at a fixed manner). See the learning guide for the full explanation. Also see the experimental locus-fix comparison — a proposed tweak to fix consonants that barely move in pitch next to certain vowels.
