Naija-ASR-Corpus v1.0 (NAC-v1.0)

A Foundational Automatic Speech Recognition Corpus for Nigerian Pidgin (Naija, PCM)

📌 Dataset Summary

Naija-ASR-Corpus (NAC-v1.0) is a speech dataset derived from the Universal Dependencies Naija Spoken Corpus (UD_Naija-NSC).

The NAC Team processed the original long-form recordings by:

Segmenting the audio into sentence-level clips.
Transcribing/Aligning the text to create paired audio-text data suitable for ASR training.

This dataset is designed to support the development of Automatic Speech Recognition (ASR) systems for Nigerian Pidgin (Naija, ISO 639-3: PCM).

🎯 Use Cases

Automatic speech recognition (ASR)
Speech-to-text research
Linguistic analysis of segmented Naija speech

🌍 Language

Language: Nigerian Pidgin (Naija)
ISO 639-3 Code: PCM

🧩 Dataset Composition

Component	Description
Total Utterances	5,883 processed speech clips
Audio Format	`.wav` files, mono, 16kHz
