- **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.

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**:
```python
from datasets import load_dataset

dataset = load_dataset("linagora/linto-dataset-audio-ar-tn-0.1")
```

Check the containt of dataset:
```python
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**
```bash
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
