Moby Project

The Moby Project is a collection of public-domain lexical resources. It was created by Grady Ward. The resources were dedicated to the public domain, and are now mirrored at Project Gutenberg. As of 2007, it contains the largest free phonetic database, with 177,267 words and corresponding pronunciations.

Hyphenator

The Moby Hyphenator II contains the hyphenations of 187,175 words and phrases (including 9,752 entries where no hyphenations are given, such as through and avoir). The character encoding appears to be MacRoman, and hyphenation is indicated by a bullet (character value 165 decimal, or A5 hexadecimal). Some entries, however, have a combination of actual hyphens and character 165, such as "bar•ber-sur•geon".

There is little to no documentation of the hyphenation choices made; the following examples might give some flavour of the style of hyphenation used: at•mos•phere; at•tend•ant; ca•pac•i•ty; un•col•or•a•ble.

Language

Moby Language II contains wordlists of five languages: French, German, Italian, Japanese, and Spanish:

Language	Words	Size (in bytes)
French	138,257	1,524,757
German	159,809	2,055,986
Italian	60,453	561,981
Japanese	115,523	934,783
Spanish	86,059	850,523
Total	560,101	5,928,030

However, some of the lists are contaminated, for example the Japanese list contains English words such as abnormal and non-words such as abcdefgh and m,./. There are also unusual peculiarities in the sorting of these lists, as the French list contains a straight alphabetical listing, while the German list contains the alphabetical listing of traditionally capitalized words and then the alphabetical listing of traditionally lower-cased words. The list of Italian words, however, contains no capitalized words whatsoever.

The foreign languages list does not use accented characters, so "e^tre" is how a user would look up the French word être ("To Be").

Part-of-Speech

Moby Part-of-Speech contains 233,356 words fully described by part(s) of speech, listed in priority order. The format of the file is word\parts-of-speech, with the following parts of speech being identified:

Plural	p
Noun phrase	h
Verb (usually participle)	V
Transitive verb	t
Intransitive verb	i
Adjective	A

Interjection	!
Pronoun	r
Definite article	D
Indefinite article	I
Nominative	o

Pronunciator

The Moby Pronunciator II contains 177,267 words with corresponding pronunciations. The Project Gutenberg distribution also contains a copy of the cmudict v0.3. The file follows the format word[/part-of-speech] pronunciation. The part-of-speech field is used to disambiguate 770 of the words which have differing pronunciations depending on their part-of-speech. For example for the words spelled close, the verb has the pronunciation /ˈkloʊz/, whereas the adjective is /ˈkloʊs/. The parts-of-speech have been assigned the following codes:

Part-of-speech	Code
Noun	n
Verb	v
Adjective	aj
Adverb	av
Interjection	interj

Following this is the pronunciation. Several special symbols are present:

Symbol	Meaning
/	Used to separate phonemes
_	Used to separate words
'	Primary stress on the following syllable
,	Secondary stress on the following syllable

The rest of the symbols are used to represent IPA characters, according to the following table:
