Overview

Concrete tool for preparing the KsponSpeech dataset for automatic speech recognition provided by the SpeechBrain library.

Description

This script creates CSV data manifest files for the KsponSpeech (Korean Spontaneous Speech) dataset. It processes raw audio files and transcriptions, generates per-split CSV files with audio paths, durations, and transcripts, and supports merging multiple splits into a single CSV. The script handles Korean text normalization and is designed for the transformer-based ASR recipe.

Usage

Use this when preparing the KsponSpeech dataset for Korean ASR training with SpeechBrain recipes.
