isiZulu Speech Recognition Augmented Dataset - 0.9x Speed

Dataset Description

This dataset contains augmented speech recordings and transcriptions for isiZulu, one of South Africa's official languages. The dataset has been optimized for use with OpenAI's Whisper ASR models.

Dataset Statistics

Number of samples: 660
Language: isiZulu (Zul)
Audio format: WAV, 16kHz, mono, 16-bit
Maximum duration: 30 seconds (truncated for Whisper compatibility)
Transcription format: Cleaned text (lowercase, no punctuation)

Audio Processing

All audio files have been processed with the following optimizations:

Resampled to 16kHz (Whisper's native sample rate)
Converted to mono
Truncated to maximum 30 seconds
16-bit PCM encoding

Transcription Cleaning

Transcriptions have been cleaned:

Converted to lowercase
Removed all punctuation
Removed POS markers (e.g., [n], [v])
Normalized whitespace

Dataset Structure

Each sample contains:

audio: Audio file path and array
transcription: Cleaned transcription text
file_id: Unique identifier for the recording
subfolder: Original subfolder location

Usage

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("zionia/isizulu-lwazi-asr-0.9")

# Access samples
print(dataset['train'][0])
