CV Korean Test 25.0 - Noise-Augmented (SCAI)

Description

This dataset is a noise-augmented version of the test split (test.csv) from the Mozilla Common Voice Scripted Speech 25.0 – Korean dataset, designed to support research in automatic speech recognition (ASR), particularly in noisy environments. The original clean speech dataset is already hosted on Mozilla Data Collective. Building upon this existing resource, we generate additional versions of the evaluation audio by applying various types of environmental noise while preserving the original transcriptions. The purpose of this dataset is to enable systematic evaluation of ASR systems under realistic acoustic conditions. The noise augmentation process simulates real-world scenarios such as background noise, allowing researchers to assess model robustness.

Dataset Structure

This dataset is a noise-augmented derivative of the Mozilla Common Voice Scripted Speech 25.0 – Korean dataset and utilizes only its test split for evaluation purposes. Therefore, the original dataset documentation should be referred to for the full data structure and metadata specifications.

The dataset is provided in JSONL format, where each line corresponds to a single audio sample and its associated metadata.

JSONL Fields

index
A unique identifier for each data instance.
raw
The relative file path to the corresponding audio file.
question_ko
The ground-truth transcription of the audio in Korean.
etc
Additional metadata fields that may be included in each entry.
