Sound Search

Search words by how they sound, using this build's retained CMUdict pronunciations: find slant rhymes grouped by tightness, find words that fit a stress pattern you tap out, or find true alliteration by first sound rather than first letter.

Letters A–Z only. Groups: perfect rhymes, multi-vowel slant rhymes, and assonance.
Tap out a stress pattern
No beats yet — add DUM and da below.
DUM is a stressed syllable, da is unstressed, dum is secondary stress.

Alliteration is matched on the first sound, not the first letter — phone alliterates with fantastic.
Or pick a first sound directly
Consonants
Vowels

About Sound Search

All three modes search pronunciations from the pinned CMUdict artifact in this data build (v1/2026.07-lexical.6). A word without a retained pronunciation never matches any sound constraint — its absence says nothing about how (or whether) it is pronounced. CMUdict primarily represents North American English, so stress, rhyme and first-sound facts can differ by dialect.

How the rhyme groups work

  • Perfect rhymes share the seed's full rhyme key — every sound from the last stressed vowel to the end of the word.
  • Multi-vowel slant rhymes are not perfect, but their last two or more vowel sounds match the seed's, compared within this build's fixed vowel families.
  • Assonance shares only the stressed-vowel nucleus family — a vowel echo without a matching ending.

Limitations

  • Rhyme grouping classifies each candidate by its primary retained pronunciation variant; the perfect-rhyme pool itself compares every retained variant.
  • Slant and assonance grouping follow a fixed, build-specific rule (vowel families plus voicing-collapsed endings). They are a deterministic approximation, not a general poetic-nearness judgement.
  • Stress patterns use digits per vowel sound: 1 primary, 0 unstressed, 2 secondary. A word matches when any retained variant's stress string equals the pattern exactly.
  • Result tiers are build-specific ranking bands from this data build, not universal usage claims, and very large candidate sets are scanned within a fixed budget (a truncation notice appears when that happens).
