Deep learning for AR text Vocalization - التشكيل الالي للنصوص العربية
The Shakkala project presents a recurrent neural network for Arabic text vocalization that automatically forms Arabic characters (تشكيل الحروف) to enhance text-to-speech systems. The model can also be used in other applications such as improving search results. In the beta version, the model was trained on over a million sentences, including a majority of historical Arabic data from books and some modern data from the internet. The accuracy of the model reached up to 95%, and in some data sets it achieved even higher levels of accuracy depending on complexity and data distribution. This innovative approach has the potential to significantly improve the quality of writing and text-to-speech systems for the Arabic language.
No GitHub repository installation is needed for pip case:
pip install shakkala
Execute the source code from Github:
cd requirements
pip install -r requirements.txt
cd ..
Note: Shakkala has been tested with Tensorflow 2.9.3.
Check full example in (demo.py) file.
from shakkala import Shakkala
sh = Shakkala()
OR for advanced usage:
sh = Shakkala(version={version_num})
input_text = "فإن لم يكونا كذلك أتى بما يقتضيه الحال وهذا أولى"
input_int = sh.prepare_input(input_text)
model, graph = sh.get_model()
logits = model.predict(input_int)[0]
predicted_harakat = sh.logits_to_text(logits)
final_output = sh.get_final_text(input_text, predicted_harakat)
Available models:
It worth to try both version_num=2 and version_num=3.
The fastest way to start with Shakkala by running the demo from Github:
python demo.py
Shakkala built in object oriented way to load the model once into memory for faster prediction, to make sure you dont load it multiple times in your service or application follow the steps:
sh = Shakkala(folder_location, version={version_num})
model, graph = sh.get_model()
input_int = sh.prepare_input(input_text)
logits = model.predict(input_int)[0]
predicted_harakat = sh.logits_to_text(logits)
final_output = sh.get_final_text(input_text, predicted_harakat)
In this beta version 2 accuracy reached up to 95% and in some data it reach more based on complexity and data disribution.
This beta version trained on more than million sentences with majority of historical Arabic data from books and some of available formed modern data in the internet.

The model can be enhanced to reach more than 95% accuracy with following:
