+# **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:
+1.  **Segmenting** the audio into sentence-level clips.
+2.  **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**

+
+**modifications by NAC Team:**
+The original continuous recordings were split into shorter clips (`pidgin_0001.wav` to `pidgin_5883.wav`) and matched with specific transcripts to facilitate machine learning tasks.
