-## Dataset Description
-The Waxal project provides datasets for both Automated Speech Recognition (ASR)
-and Text-to-Speech (TTS) for African languages. The goal of this dataset's
-creation and release is to facilitate research that improves the accuracy and
-fluency of speech and language technology for these underserved languages, and
-to serve as a repository for digital preservation.
-The Waxal datasets are collections acquired through partnerships with Makerere
-University, The University of Ghana, Digital Umuganda, and Media Trust.
-Acquisition was funded by Google and the Gates Foundation under an agreement to
-make the dataset openly accessible.
-### ASR Dataset
-The Waxal ASR dataset is a collection of data in 14 African languages. It
-consists of approximately 1,250 hours of transcribed natural speech from a wide
-variety of voices. The 14 languages in this dataset represent over 100 million
-speakers across 40 Sub-Saharan African countries.

-### TTS Dataset
-The Waxal TTS dataset is a collection of text-to-speech data in 10 African
-languages. It consists of approximately 240 hours of scripted natural speech
-from a wide variety of voices.

-### How to Use
-The `datasets` library allows you to load and pre-process your dataset in pure
-Python, at scale.
-First, ensure you have the necessary dependencies installed to handle audio
-data:
-```bash
-pip install datasets[audio]
-```
-**Loading ASR Data**
-To load ASR data, point to the `data/ASR` directory.
-```python
-from datasets import load_dataset, Audio
-# Load Shona (sna) ASR dataset
-asr_data = load_dataset("google/WaxalNLP", "sna", data_dir="data/ASR")
-# Access splits
-train = asr_data['train']
-val = asr_data['validation']
-test = asr_data['test']
-# Example: Accessing audio bytes and other fields
-example = train[0]
-print(f"Transcription: {example['transcription']}")
-print(f"Sampling Rate: {example['audio']['sampling_rate']}")
-# 'array' contains the decoded audio bytes as a numpy array
-print(f"Audio Array Shape: {example['audio']['array'].shape}")
-```
-**Loading TTS Data**
-To load TTS data, point to the `data/TTS` directory.
-```python
-from datasets import load_dataset
-# Load Swahili (swa) TTS dataset
-tts_data = load_dataset("google/WaxalNLP", "swa", data_dir="data/TTS")
-# Access splits
-train = tts_data['train']
-```
-## Dataset Structure
-### ASR Data Fields
-```python
-{
-  'id': 'sna_0',
-  'speaker_id': '...',
-  'audio': {
-    'array': [...],
-    'sample_rate': 16_000
-  },
-  'transcription': '...',
-  'language': 'sna',
-  'gender': 'Female',
-}
-```
-*   **id**: Unique identifier.
-*   **speaker_id**: Unique identifier for the speaker.
-*   **audio**: Audio data.
-*   **transcription**: Transcription of the audio.
-*   **language**: ISO 639-2 language code.
-*   **gender**: Speaker gender ('Male', 'Female', or empty).
-### TTS Data Fields
-```python
-{
-  'id': 'swa_0',
-  'speaker_id': '...',
-  'audio': {
-    'array': [...],
-    'sample_rate': 16_000
-  },
-  'transcription': '...',
-  'locale': 'swa',
-  'gender': 'Female',
-}
-```
-*   **id**: Unique identifier.
-*   **speaker_id**: Unique identifier for the speaker.
-*   **audio**: Audio data.
-*   **transcription**: Transcription.
-*   **locale**: ISO 639-2 language code.
-*   **gender**: Speaker gender.
-### Data Splits
-For the **ASR Dataset**, the data with transcriptions is split as follows: *
-**train**: 80% of labeled data. * **validation**: 10% of labeled data. *
-**test**: 10% of labeled data.
-The **unlabeled** split contains all samples that do not have a corresponding
-transcription.
-The **TTS Dataset** follows a similar structure, with data split into `train`,
-`validation`, and `test` sets.
-## Dataset Curation
-The data was gathered by multiple partners:
-Provider            | Dataset                                                  | License
