Request parameters

Name	Description
word	The rhyming word
lang	ISO639-1 language code (optional). Eg. en, de, es, fr, ru
maxResults	(optional) The number of results to return. If you do not include this parameter, RhymeBrain will choose how many words to show based on how many good sounding rhymes there are for the word.

Response

Each result is an object with these members:

Name	Description
word	The rhyming word
score	The RhymeRankTM score for the word. Scores of 300 and above are perfect rhymes. Scores between 0 and 300 are near rhymes without similar sounding consonents. Words with the same score are listed with the most matching sounds first. If you later sort by score again, it is best to preserve this ordering before showing the results to the user.
flags	A list of letters giving more information about the word. a: The word is offensive. b: The word might be found in most dictionaries. c: The pronunciation is known with confidence. It was not automatically generated.
syllables	An estimate of the number of syllables in the rhyming word.
freq	A number that tells you how common the word is. The number is a logarithm of the frequency of usage in common texts. Currently, the highest possible value is 34.

You can ask RhymeBrain to return everything it knows about a word, including its pronunciation and other flags.

Response

Name	Description

pron	The result is a string containing the phonetic transcription of the word. The arpabet format used is described here. The flags indicate whether the pronunciation is automatically generated or not. An automatically generated pronunciation might not be accurate.
ipa	The phonetic transcription using the International Phonetic Alphabet. This transcription might contain unicode characters. Since the response is in JSON format, the unicode characters are encoded using the \u syntax.
flags	A list of letters giving more information about the word. a: The word is offensive. b: The word might be found in most dictionaries. c: The pronunciation is known with confidence. It was not automatically generated.

If you are making too many requests, they will be automatically limited. In that case, you will get back an error. Each individual query in a request counts towards the limit. The rate limiting is performed according to the "leaky bucket" algorithm.

The current rate limit is 350 requests per hour.

Steve Hanov lives in Waterloo, Ontario, Canada, and occasionally works on RhymeBrain when allowed by his wife, Alice, and two small daughters. Since 2009, Steve has been tweaking the rhyming algorithm to present better results and add new human languages. He has had to learn about linguistics, information retrieval, statistics, and, unfortunately, linear algebra to build this system.

RhymeBrain uses machine learning to derive the pronunciation of words. Rhymes are not stored, but computed automatically for each request by finding words that sound similar.

Steve sometimes writes about the technical things on his blog.
