🐶 Murre 🐕

Downloads

CC BY NC ND

The amazing Murre (genitive Murren 🐕) will normalize non-standard Finnish (puhekieli) to standard Finnish (kirjakieli). This repository is maintained by Mika Hämäläinen.

Installation

This library is designed for Python 3 and it may not work on Python 2.

pip3 install murre
python3 -m murre.download

Normalize

To normalize Finnish, all you need to do is to run:

from murre import normalize_sentence

normalize_sentence("mä syön paljo karkkii")
>> minä syön paljon karkkia

You can normalize multiple sentences at the same time by running

from murre import normalize_sentences

sents = ["kissa syö karkkii", "jok laulaa tuol puole", "en tiiä oikee et kuka se o", "kyl on hölömöö"]
normalize_sentences(sents)
>> ['kissa syö karkkia', 'joka laulaa tuolla puolen', 'en tiedä oikein että kuka se on', 'kyllä on hölmöä']

Historical Finnish

To normalize (and lemmatize) historical Finnish, run:

from murre import normalize_sentence

normalize_sentence("paluellen herra caiken", language="fin_hist")
>> palvella herra kaikki

Swedish

You can use the Swedish model by passing language=swe

from murre import normalize_sentence

normalize_sentence("int vet ja", language="swe")
>> inte vet jag

Generate

Murre can also generate different dialects. All you need to do, is to run:

from murre import dialectalize_sentence
dialectalize_sentence("kodin takana on koira", "Inkerinsuomalaismurteet")
>> 'kojin takan on koira'

Or for multiple sentences:

from murre import dialectalize_sentences
sents = ["kissa syö karkkia", "kädellä on perhonen", "kettu juoksee sutta karkuun"]
dialectalize_sentences(sents,'Kainuu')
>> ['kissa syöpi karkkia', 'käellä om perhonej', 'kettu juoksee sutta karkuu']

The list of available dialects can be obtained by:

from murre import supported_dialects
supported_dialects()
>> ['Pohjois-Satakunta', 'Keski-Karjala', 'Kainuu', 'Etelä-Pohjanmaa', 'Etelä-Satakunta', 'Pohjois-Savo', 'Pohjois-Karjala', 'Keski-Pohjanmaa', 'Kaakkois-Häme', 'PohjoinenKeski-Suomi', 'Pohjois-Pohjanmaa', 'PohjoinenVarsinais-Suomi', 'Etelä-Karjala', 'Länsi-Uusimaa', 'Inkerinsuomalaismurteet', 'LäntinenKeski-Suomi', 'Länsi-Satakunta', 'Etelä-Savo', 'Länsipohja', 'Pohjois-Häme', 'EteläinenKeski-Suomi', 'Etelä-Häme', 'Peräpohjola']
