klaam

Arabic speech recognition, classification and text-to-speech using many advanced models like wave2vec and fastspeech2. This repository allows training and prediction using pretrained models.

Usage

from klaam import SpeechClassification
model = SpeechClassification()
model.classify(wav_file)

from klaam import SpeechRecognition
model = SpeechRecognition()
model.transcribe(wav_file)

from klaam import TextToSpeech
model = TextToSpeech()
model.synthesize(sample_text)

There are two avilable models for recognition trageting MSA and egyptian dialect . You can set any of them using the lang attribute

 from klaam import SpeechRecognition
 model = SpeechRecognition(lang = 'msa')
 model.transcribe('file.wav')

Dataset	Description	link
MGB-3	Egyptian Arabic Speech recognition in the wild. Every sentence was annotated by four annotators. More than 15 hours have been collected from YouTube.	requires registeration here
ADI-5	More than 50 hours collected from Aljazeera TV. 4 regional dialectal: Egyptian (EGY), Levantine (LAV), Gulf (GLF), North African (NOR), and Modern Standard Arabic (MSA). This dataset is a part of the MGB-3 challenge.	requires registeration here

Models

We currently support four models, three of them are avilable on transformers.

Training

The scripts are a modification of jqueguiner/wav2vec2-sprint.

Text To Speech

We use the pytorch implementation of fastspeech2 by ming024. The procedure is as follows

Download the dataset

wget http://en.arabicspeechcorpus.com/arabic-speech-corpus.zip 
unzip arabic-speech-corpus.zip

Create multiple directories for data

mkdir -p raw_data/Arabic/Arabic preprocessed_data/Arabic/TextGrid/Arabic
cp arabic-speech-corpus/textgrid/* preprocessed_data/Arabic/TextGrid/Arabic

Prepare metadata

import os 
base_dir = '/content/arabic-speech-corpus'
lines = []
for lab_file in os.listdir(f'{base_dir}/lab'):
  lines.append(lab_file[:-4]+'|'+open(f'{base_dir}/lab/{lab_file}', 'r').read())


open(f'{base_dir}/metadata.csv', 'w').write(('\n').join(lines))

Clone my fork

git clone --depth 1 https://github.com/zaidalyafeai/FastSpeech2
cd FastSpeech2
pip install -r requirements.txt

Prepare alignments and prepreocessed data

python3 prepare_align.py config/Arabic/preprocess.yaml
python3 preprocess.py config/Arabic/preprocess.yaml

Unzip vocoders

unzip hifigan/generator_LJSpeech.pth.tar.zip -d hifigan
unzip hifigan/generator_universal.pth.tar.zip -d hifigan

Start training

python3 train.py -p config/Arabic/preprocess.yaml -m config/Arabic/model.yaml -t config/Arabic/train.yaml
