Multi-Domain Haitian_creole Speech Dataset

This dataset contains 12 audio recordings with corresponding text transcriptions across multiple languages and domains.

Dataset Description

A comprehensive collection of audio files paired with text transcriptions, featuring both synthetic and natural speech across various domains. Suitable for automatic speech recognition (ASR), text-to-speech (TTS), and domain-specific speech processing tasks.

Dataset Structure

Each entry contains:

• id: Unique identifier (UUID)
• text: Transcription text in the specified language
• audio: URL to the audio file (with AWS S3 signed URLs)
• nature: Type of audio (e.g., "synthetic", "natural")
• language: Language of the audio/text
• domain: Domain/topic category (e.g., "agriculture", "healthcare", "education")

Languages

This dataset includes the following languages:

• Haitian_creole (ha): haitian_creole

Domains

Content spans across multiple domains:

• Healthcare: Domain-specific terminology and context

Audio Nature

The dataset includes different types of audio:

• Human: Natural human speech

Usage

from datasets import load_dataset
import json
import requests
from io import BytesIO
import pandas as pd

# Load using datasets library
dataset = load_dataset("jsbeaudry/med-cre")

# Or load JSON directly
with open("dataset.json", "r", encoding="utf-8") as f:
    data = json.load(f)

print(f"Dataset contains {len(data)} audio-text pairs")

# Create DataFrame for analysis
df = pd.DataFrame(data)
print("\nDataset breakdown:")
print(f"Languages: {df['language'].value_counts().to_dict()}")
print(f"Domains: {df['domain'].value_counts().to_dict()}")
print(f"Nature: {df['nature'].value_counts().to_dict()}")

# Filter by criteria
swahili_agriculture = [item for item in data 
                      if item['language'] == 'swahili' and item['domain'] == 'agriculture']
print(f"\nSwahili agriculture samples: {len(swahili_agriculture)}")

# Example: Download and process audio
def download_audio(url):
    response = requests.get(url)
    return BytesIO(response.content)

# Get first audio file
audio_data = download_audio(data[0]['audio'])
print(f"Audio downloaded for: {data[0]['text'][:50]}...")

Audio Format

Audio files are stored locally in the dataset as WAV files. When loaded with the datasets library, audio is automatically converted to the standard format:

• Format: WAV
• Sampling Rate: Preserved from original (typically 16kHz or 22kHz)
• Channels: Mono
• Bit Depth: 16-bit or 32-bit float
• Access: Direct array access via dataset['train'][index]['audio']['array']

Use Cases

This dataset can be used for:

Speech Recognition (ASR)

• Multi-language speech recognition systems
• Domain-specific ASR models (agriculture, healthcare, etc.)
• Synthetic vs. natural speech detection

Text-to-Speech (TTS)

• Multi-language TTS systems
• Domain-adaptive speech synthesis
• Voice quality evaluation (synthetic vs. natural)

Research Applications
