Data Proccessing:

• Audio Alignment: Matching audio segments with corresponding text to ensure accurate transcription and contextual alignment.
• Transcription Correction: Reviewing and correcting transcriptions to address errors and discrepancies in the initial text.
• Standardization: Converting words and phrases into their standardized forms to maintain consistency across the dataset.
• Padding: Adding padding to shorter audio segments to address issues with Kaldi and ensure uniformity in input lengths.
• Silence Removal: Eliminating segments of audio that contain only silence to improve dataset efficiency and relevance.
• Annotation: Labeling audio segments that require transcriptions and other metadata. Ensuring that non-annotated audio is reviewed and annotated if necessary.

Content Types

• Music: Includes recordings of different music genres.
• FootBall: Includes recordings of football news and reviews.
• Documentaries: Audio from documentaries about history and nature.
• Podcasts: Conversations and discussions from various podcast episodes.

• Testing Set: onsists of a varied set of audio recordings, also covering different contexts, dedicated to assessing the model’s performance and generalization.

This composition ensures a comprehensive representation of various audio types and linguistic features, making the dataset valuable for a range of ASR research and development tasks.

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")

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.]
