NE ASR Augmented Dataset -- Mizo (lus)

Augmented automatic speech recognition dataset for Mizo (lus), a Tibeto-Burman language spoken in Mizoram, India.

Source

Augmented from sulabhkatiyar/ne-asr-lus (original transcribed speech data from the ARTPARK-IISc Vaani project).

Language Information

Property	Value
Language	Mizo
ISO 639-3	`lus`
Family	Tibeto-Burman
Region	Mizoram, India
Tonal	Yes
Tier	D (20.75h original data)

Dataset Statistics

Original training samples: 9,850
Augmented training samples: 29,550 (3x augmentation)
Train shards: 50
Estimated original duration: ~20.8 hours
Estimated augmented duration: ~62.2 hours

Split	Samples
train	29,550
validation	1,190
test	1,218

Transformations Applied

Each original training sample produces 3 samples (1 original + 2 speed + 0 pitch):

Speed perturbation: 0.9x, 1.1x (2 variants per sample)
Pitch shift: Disabled (tonal language -- pitch shift would alter lexical meaning)
Noise augmentation: Not applied

SpecAugment Parameters (for training, NOT in this dataset)

These parameters are consumed by the training script and are not baked into the audio files:

mask_time_prob: 0.1
mask_time_length: 10
mask_feature_prob: 0.05
mask_feature_length: 10
layerdrop: 0.05

Full augmentation config: configs/augmentation_config.yaml

Dataset Format

Audio: 16kHz mono WAV (stored as Parquet with audio bytes)
Text: Transcriptions
Features: audio, text, language, augmentation
Augmentation labels: original, speed_0.9, speed_1.1

How to Use

from datasets import load_dataset

# Load the full dataset
ds = load_dataset("sulabhkatiyar/ne-asr-lus-aug")

# Load only the training split
train = load_dataset("sulabhkatiyar/ne-asr-lus-aug", split="train")

# Filter to only original (non-augmented) samples
original_only = train.filter(lambda x: x["augmentation"] == "original")

# Filter to a specific augmentation type
speed_09 = train.filter(lambda x: x["augmentation"] == "speed_0.9")
