Installation :

install kenlm

install DeepSpeech

git clone https://github.com/silenterus/deepspeech-cleaner cd deepspeech-cleaner pip install -r requirements.txt

Quick Start

Downloader

download/analyze/insert all available corpora for french

python3 deepspeech-cleaner.py download --lang fr

Inserter

insert corpora - in case you download the files by yourself

python3 deepspeech-cleaner.py insert /path/to/corpora/

Creator

clean/sort/create all necessary files for training - includes lm.binary/trie if kenlm is installed

python3 deepspeech-cleaner.py create

clean/sort/create all necessary files for training - no cleaning and no lm.binary/trie creation

python3 deepspeech-cleaner.py create --noclean --notrie

start deepspeech training

bash languages/fr/training/standard/start_train.sh

Other Options

Wiki Crawler

download/extract/clean articles from Wiki Dumps

python3 deepspeech-cleaner.py crawl

Replacement Tester

Test num2words and your replacement rules

python3 deepspeech-cleaner.py test 1 2 3 is not for me python3 deepspeech-cleaner.py test /path/to/textfile.txt

Audio Transformer

convert/trimm/trimmsilence all audio files in your Database

python3 deepspeech-cleaner.py convert

Autosave

all arguments are saved for each language seperately

autosave off/on

python3 deepspeech-cleaner.py autosave

Hints

change replacer rules in

languages/fr/replacer/..

files contain rules like

'@> ' ' Sat > Saturday '

only files with a number attached will be used
<0 used before number translation
=>0 used after number translation
replace a word/symbol with '�' and the whole sentence get rejected
spaces at the start/end are important for whole words

change the string based sql querys in

languages/fr/sql_query/..

files are named like the tables in your "audio.db"
'!' at the end of a line functions as NOT
