Dataset Summary

The LinTO DataSet Audio for Arabic Tunisian Augmented v0.1 is a dataset that builds on LinTO DataSet Audio for Arabic Tunisian v0.1, using a subset of the original audio data. Augmentation techniques, including noise reduction and SoftVC VITS Singing Voice Conversion (SVC), have been applied to enhance the dataset for improved performance in Arabic Tunisian Automatic Speech Recognition (ASR) tasks.

Dataset Composition:

The LinTO DataSet Audio for Arabic Tunisian Augmented v0.1 comprises a diverse range of augmented audio samples using different techniques. Below is a breakdown of the dataset’s composition:

Data Proccessing:

Noise Reduction: Applying techniques to minimize background noise and enhance audio clarity for better model performance. For this, we used Deezer Spleeter, a library with pretrained models, to separate vocals from music.
Voice Conversion: Modifying speaker characteristics (e.g., pitch) through voice conversion techniques to simulate diverse speaker profiles and enrich the dataset. For this, we chose SoftVC VITS Singing Voice Conversion (SVC) to alter the original voices using 7 different pretrained models.

Content Types

FootBall: Includes recordings of football news and reviews.
Documentaries: Audio from documentaries about history and nature.
Podcasts: Conversations and discussions from various podcast episodes.
Authors: Audio recordings of authors reading or discussing different stories: horror, children's literature, life lessons, and others.
Lessons: Learning resources for the Tunisian dialect.
Others: Mixed recordings with various subjects.

Languages and Dialects

Tunisian Arabic: The primary focus of the dataset, including Tunisian Arabic and some Modern Standard Arabic (MSA).
French: Some instances of French code-switching.
English: Some instances of English code-switching.

Characteristics

Audio Duration: The dataset contains more than 317 hours of audio recordings.
Segments Duration: This dataset contains segments, each with a duration of less than 30 seconds.
Labeled Data: Includes annotations and transcriptions for a significant portion of the audio content.

Data Distribution

Training Set: Includes a diverse range of augmented audio with 5 to 7 different voices, as well as noise reduction applied to two datasets.

Example use (python)

Load the dataset in python:

from datasets import load_dataset

# dataset will be loaded as a DatasetDict of train and test
dataset = load_dataset("linagora/linto-dataset-audio-ar-tn-augmented-0.1")

Check the containt of dataset:

example = dataset['train'][0] 
audio_array = example['audio']["array"]
segments = example['segments']
transcription = example['transcript']

print(f"Audio array: {audio_array}")
print(f"Segments: {segments}")
print(f"Transcription: {transcription}")

Example

Audio array: [0. 0. 0. ... 0. 0. 0.]
Transcription: أسبقية قبل أنا ما وصلت خممت فيه كيما باش نحكيو من بعد إلا ما أنا كإنطريبرنور كباعث مشروع صارولي برشا مشاكل فالجستين و صارولي مشاكل مع لعباد لي كانت موفرتلي اللوجسيل ولا اللوجسيل أوف لنيه ولا لوجسيل بيراتي
segments: [{'end': 14.113, 'start': 0.0, 'transcript': 'أسبقية قبل أنا ما وصلت خممت فيه كيما باش نحكيو من بعد إلا ما أنا كإنطريبرنور كباعث مشروع صارولي برشا مشاكل فالجستين و صارولي مشاكل مع لعباد لي كانت موفرتلي اللوجسيل ولا اللوجسيل أوف لنيه ولا لوجسيل بيراتي'}]
