+
+### Overview and Purpose
+
+**AfriSpeech-Dialog** is a pan-African conversational speech dataset with 6 hours of recorded dialogue, designed to support speech recognition (ASR), speaker diarization, and language modeling applications. Collected from diverse accents across Nigeria, Kenya, and South Africa, the dataset offers valuable insights into the varied linguistic and phonetic characteristics found in African-accented English. This release includes 50 conversations across both medical and general topics.

+### Use Cases
+This dataset is tailored for use in:
+- Automatic Speech Recognition (ASR) fine-tuning
+- Speaker Diarization training and testing
+
+
+### Dataset Composition
+
+- **Languages and Accents**: The dataset includes 11 accents: Hausa, Isoko, Idoma, Urhobo, Ijaw, Yoruba, Swahili, Sesotho, Igbo, Igala, and Ebira.

+- **Participants**: The dataset includes both male and female speakers.
+- **Structure of Conversations**: Conversations are two-speaker free-form dialogues.
+
+### Data Collection and Processing
+
+- **Collection Method**: Conversations were collected remotely across various acoustic environments as stored as `.wav` files.
+- **Annotation**: Each conversation is annotated with speaker labels and timestamps, including start and end times for each speaker’s turn.
+
+### Key Columns and Fields
