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.

1. Usage

1.1 Speech Classification

fromklaamimportSpeechClassificationmodel=SpeechClassification()
model.classify(wav_file)

1.2 Speech Recongnition

fromklaamimportSpeechRecognitionmodel=SpeechRecognition()
model.transcribe(wav_file)

1.3 Text To Speech

fromklaamimportTextToSpeechprepare_tts_model_path="../cfgs/FastSpeech2/config/Arabic/preprocess.yaml"model_config_path="../cfgs/FastSpeech2/config/Arabic/model.yaml"train_config_path="../cfgs/FastSpeech2/config/Arabic/train.yaml"vocoder_config_path="../cfgs/FastSpeech2/model_config/hifigan/config.json"speaker_pre_trained_path="../data/model_weights/hifigan/generator_universal.pth.tar"model=TextToSpeech(prepare_tts_model_path, model_config_path, train_config_path, vocoder_config_path, speaker_pre_trained_path)
model.synthesize(sample_text)

There are two avilable models for recognition trageting Modern Standard Arabic (MSA) and Egyptian dialect (EGY) . You can set any of them using the lang attribute.

fromklaamimportSpeechRecognitionmodel=SpeechRecognition(lang='msa')
model.transcribe('file.wav')

5. Training

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

5.1. Classification

This script is used for the classification task on the 5 classes.

python run_classifier.py \
--model_name_or_path="facebook/wav2vec2-large-xlsr-53" \
--output_dir=/path/to/output \
--cache_dir=/path/to/cache/ \
--freeze_feature_extractor \

--save_steps="100" \
--eval_steps="100" \
--save_total_limit="1" \
--logging_steps="100" \

--do_train \

5.2. Recognition

This script is for training on the dataset for pretraining on the egyption dialects dataset.

python run_mgb3.py \
--model_name_or_path="facebook/wav2vec2-large-xlsr-53" \
--output_dir=/path/to/output \
--cache_dir=/path/to/cache/ \

5.3. Text To Speech

We use the pytorch implementation of fastspeech2 by ming024.

The procedure is as the following:

1. Download the dataset and unzip it.

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

2. 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

3. Prepare metadata

importosbase_dir='/content/arabic-speech-corpus'lines= []
forlab_fileinos.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))

4. Clone my repository (FastSpeech2) and installl the dependencies required.

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

5. Prepare alignments and prepreocessed data.

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

6. Unzip vocoders.

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

7. Start the training.

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