Text.Sonnex

This package computes Sonnex codes for french words or phrases. It is an alternative to the Soundex algorithm for french language.

Characters of the Sonnex code

The Sonnex code contains the following characters:

• 1 ← un, ein, in, ain
• 2 ← en, an
• 3 ← on
• a ← a, à, â
• b ← b, bb
• C ← ch
• d ← d, dd
• e ← e, eu
• E ← ê, é, è, ai, ei
• f ← f, ff, ph
• g ← gu
• i ← î, i, ille
• j ← j, ge
• k ← k, c, qu, ck
• l ← l, ll
• m ← m, mm
• n ← n, nn
• o ← o, ô
• p ← p, pp
• r ← r, rr
• s ← s, ss
• t ← t, tt
• u ← u, ù, û
• v ← v, w
• z ← z, s
• U ← ou

The apostroph is ignored, every other character not understood by the Sonnex algorthim is copied without changes.

Documentation

sonnex :: String -> String

Compute a Sonnex code for a french word.

The string must contain only one word. Each character should be considered as being vocal, not silent

length (sonnex w) <= length w

sonnexPhrase :: String -> String

Compute a Sonnex code for a french phrase.

It applies the sonnex function to each word in the phrase. Since it uses the words/unwords couple, superfluous space character are removed.
