# test3

This is a merged speech dataset containing 345 audio segments from 2 source datasets.

## Dataset Information

- **Total Segments**: 345
- **Speakers**: 7
- **Languages**: en
- **Emotions**: happy, neutral, angry, sad
- **Original Datasets**: 2

## Dataset Structure

Each example contains:
- `audio`: Audio file (WAV format, 16kHz sampling rate)
- `text`: Transcription of the audio
- `speaker_id`: Unique speaker identifier (made unique across all merged datasets)
- `emotion`: Detected emotion (neutral, happy, sad, etc.)
- `language`: Language code (en, es, fr, etc.)

## Usage

### Loading the Dataset

```python
from datasets import load_dataset

# Load the dataset
dataset = load_dataset("Codyfederer/test3")

# Access the training split
train_data = dataset["train"]

# Example: Get first sample
sample = train_data[0]
print(f"Text: {sample['text']}")
print(f"Speaker: {sample['speaker_id']}")
print(f"Language: {sample['language']}")
print(f"Emotion: {sample['emotion']}")

# Play audio (requires audio libraries)
# sample['audio']['array'] contains the audio data
# sample['audio']['sampling_rate'] contains the sampling rate
```

### Alternative: Load from CSV

```python
import pandas as pd
from datasets import Dataset, Audio, Features, Value

# Load the CSV file
df = pd.read_csv("data.csv")

# Define features
features = Features({
    "audio": Audio(sampling_rate=16000),
    "text": Value("string"),
    "speaker_id": Value("string"),
    "emotion": Value("string"),
    "language": Value("string")
})

# Create dataset
dataset = Dataset.from_pandas(df, features=features)
```

### Dataset Structure

The dataset includes:
- `data.csv` - Main dataset file with all columns
- `segments/` - Directory containing all audio files  
- `load_dataset.txt` - Python script for loading the dataset (rename to .py to use)

CSV columns:
- `audio`: Path to the audio file (in segments/ directory)
- `text`: Transcription of the audio
- `speaker_id`: Unique speaker identifier
- `emotion`: Detected emotion
- `language`: Language code

## Speaker ID Mapping

Speaker IDs have been made unique across all merged datasets to avoid conflicts.
For example:
- Original Dataset A: `speaker_0`, `speaker_1`
- Original Dataset B: `speaker_0`, `speaker_1`
- Merged Dataset: `speaker_0`, `speaker_1`, `speaker_2`, `speaker_3`

Original dataset information is preserved in the metadata for reference.

## Data Quality

This dataset was created using the Vyvo Dataset Builder with:
- Automatic transcription and diarization
- Quality filtering for audio segments
- Music and noise filtering
- Emotion detection
- Language identification
