Leyu Amharic - Wello Dialect Speech Corpus

Dataset Description

This dataset is a curated parallel speech corpus consisting of audio recordings paired with corresponding text transcripts, focused on the Wello dialect of the Amharic language. It is designed to support speech technology research across multiple tasks, including Automatic Speech Recognition (ASR) and Text-to-Speech (TTS). The corpus captures dialect-specific phonetic variations, accent patterns, and prosodic characteristics unique to the Wello region.

All recordings were collected in real-world environments using mobile devices, introducing natural acoustic variability that improves model generalization. Each audio–text pair underwent manual review to ensure transcript accuracy and audio clarity.
