+This document outlines the protocols and procedures used during the data collection phase of the Speech Recognition Bias Reduction Project.
+
+## 1. Research Overview
+The study aims to gather voice recordings from non-native English speakers to enhance automated speech recognition systems' accuracy. The dataset will include audio recordings of participants spelling names, reading phone numbers, and reciting addresses, along with relevant metadata.
+
+## 2. Participant Recruitment
+- **Target Population:** International and Native students at Duke University with diverse linguistic backgrounds.
+- **Recruitment Channels:** Participants were recruited through email lists, student groups, and social media platforms.
+
+## 3. Informed Consent Process
+Participants were provided with a detailed consent form explaining the study's purpose, data usage, and their rights as participants. Consent was obtained through a simple text input ("Yes") within the survey.
+
+## 4. Recording Process
+- **Platform:** Audio recordings were collected via the Qualtrics Survey App, accessible on both laptops and mobile devices.
+- **Recording Instructions:** Participants were given clear instructions on how to record their audio:
+  - Spell out a randomized name letter by letter.
+  - Read out a randomized phone number digit by digit.
+  - Recite a randomized address clearly.
+
+## 5. Audio Quality and Environment
+Participants were instructed to record their audio in their natural environments to capture realistic conditions, which may include background noise. The recordings aimed to reflect typical conditions under which users interact with automated voice systems.
+
+## 6. Data Management
+- **Anonymization:** All participant data, including audio recordings and metadata, is anonymized to protect participant identities before public release.
+- **Withdrawal Option:** Participants were informed that they could withdraw their recordings before the dataset is made publicly accessible.

+# Dataset Description
+
+This document provides a detailed description of the dataset's contents, structure, and the significance of each component.
+
+## 1. Audio Recordings
+The dataset includes audio recordings of participants spelling out a randomized full name, a phone number, and an address. Each participant's audio files are stored in separate folders under the `audio_data/` directory.
+
+### Audio Files Naming Convention
+- `audio_data/Names`: Audio of participants spelling out a randomized name letter by letter.
+- `audio_data/Numbers`: Audio of participants reading out a randomized phone number digit by digit.
+- `audio_data/Addresses`: Audio of participants stating randomized address clearly.
+
+The folders contain raw audio files in multiple formats, such as .wav, .mp3, and .m4a. Each participant is assigned a unique file_name, which corresponds to three specific file names in the above folders. The ground truth data, including participant names, phone numbers, and addresses, is stored in the metadata.csv file.
+
+## 2. Metadata
+The accompanying metadata file `metadata.csv` contains essential information about each participant. The columns in the metadata file include:
+
+| Column Name                | Description                                                                                           |
+|----------------------------|-------------------------------------------------------------------------------------------------------|
+| **file_name**            | Unique identifier for each participant's response.                                                   |                                                             |
+| **Age**                    | Age of the participant in years.                                                                     |
+| **Gender**                 | Gender of the participant (e.g., Male, Female, Non-binary).                                          |
+| **Nationality**            | Participant's nationality.                                                                           |
+| **Native Language**        | The language the participant primarily speaks.                                                       |
+| **Familiarity with English** | Self-reported level of familiarity with English       |
+| **Accent Strength (Self reported)**        | Self-reported strength of the participant's accent on a scale from 0 (no noticeable accent) to 10.   |
+| **Difficulties**           | Self-reported frequency of difficulty with automated systems |
+| **Recording Machine**      | Device used by the participant for recording (e.g., phone recorder, external microphone).            |
+| **Name**                   | Name recorded by the participant.                                                                             |
+| **Number**                 | Number recorded by the participant.                                                                     |
+| **Address**                | Address recorded by the participant.                                                                |
+| **Duration_secs**          | Time it took to complete the survey.                                                                |
+
+## 3. Significance of the Dataset
+The dataset is crucial for:
+- Reducing bias in automated speech recognition systems, particularly for non-native speakers.
+- Providing researchers and developers with a resource to enhance their understanding of how different accents affect speech recognition accuracy.
+- Supporting the development of more inclusive technologies.
+
+## 4. How to Access the Data
+You can access the Alphanumeric Audio Dataset in two ways:
+
+1. Hugging Face (Recommended):
+
+To directly load the dataset into your project using the Hugging Face datasets library, use the following Python code:
+```
+from datasets import load_dataset
+
+dataset = load_dataset("sakshee05/alphanumeric-audio-dataset")
+```
+
+2. Github
+Access at [alphanumeric-audio-dataset](https://github.com/Sakshee5/alphanumeric-audio-dataset)
