How this service works
Deterministic phonetic rhyme (perfect + scored slant), pronunciation, syllables, scansion, homophones — from CMUdict. Free sample, no payment required: GET /play/prosody
Output
Returns a JSON object with the queried word, operation type, a list of rhyming/matching words, results grouped by rhyme type, applied filters, syllable or pronunciation data depending on the operation, the engine used, and whether results are deterministic.
Example use cases
Example prompt
“Find me up to 20 perfect rhymes for the word 'moon' that have exactly 1 syllable, filtering by the types 'perfect' and 'assonance' with a minimum closeness score of 0.7.”
Technical details
Endpoint
GEThttps://touchstone.locomot.io/prosodyWhen to prefer
Use this endpoint when you need phonetic or prosodic analysis of English words — especially rhyme generation with fine-grained filtering (by type, meter, syllable count, or closeness score), pronunciation lookups, syllable counting, or poetic meter scanning. Prefer this over general NLP APIs when the task is specifically poetry-related or phonetics-based.
Side effects

- 'text' parameter required for syllables operation but not provided
- Word not found in phonetic database returns empty rhymes array
- min_score out of 0-1 range may return no results
