# Vietnamese IPA Dataset

A comprehensive Vietnamese IPA (International Phonetic Alphabet) dataset with word pronunciations and MP3 audio files for text-to-speech and pronunciation learning applications.

## Dataset Description

### Dataset Summary

This dataset contains 50 common Vietnamese words with their IPA (International Phonetic Alphabet) transcriptions and corresponding audio files. It's designed for:
- Text-to-speech systems development
- Vietnamese pronunciation learning
- Phonetic research
- Language learning applications

### Supported Tasks

- **Text-to-Speech**: Generate Vietnamese speech from text
- **Pronunciation Learning**: Learn correct Vietnamese pronunciation with IPA
- **Phonetic Analysis**: Study Vietnamese phonetics with accurate IPA transcriptions

### Languages

Vietnamese (`vi`)

## Dataset Structure

### Data Instances

Each instance contains:
- A Vietnamese word or phrase
- Its IPA transcription with tone marks
- Path to the corresponding MP3 audio file

### Data Fields

- `word` (string): Vietnamese word or phrase
- `ipa` (string): IPA transcription with tone marks
- `audio_file` (string): Path to MP3 audio file

### Data Splits

The dataset contains a single training split with 50 examples.

## Dataset Creation

### Curation Rationale

This dataset was created to provide a simple, accessible resource for Vietnamese pronunciation with accurate IPA transcriptions and audio, addressing the lack of small-scale Vietnamese phonetic datasets.

### Source Data

#### Initial Data Collection

Words were selected from common Vietnamese vocabulary including:
- Greetings and basic phrases
- Family terms
- Numbers
- Time expressions
- Common nouns and verbs

### Annotations

#### Annotation Process

IPA transcriptions were created following standard Vietnamese phonetic conventions, including tone marks:
- ˧˧ (33): Level tone (ngang)
- ˨˩ (21): Falling tone (huyền)
- ˧˩ˀ (32ˀ): Falling-rising tone (hỏi)
- ˧˥ (35): Rising tone (sắc)
- ˧˩˧ (313): Broken tone (ngã)
- ˨˩ˀ (21ˀ): Drop tone (nặng)

Audio files were generated using Google Text-to-Speech (gTTS) for consistency.

## Usage

### Quick Start

```python
import pandas as pd

# Load the dataset
df = pd.read_csv('vietnamese_ipa_dataset.csv')

# Access word, IPA, and audio file
for idx, row in df.iterrows():
    word = row['word']
    ipa = row['ipa']
    audio_file = row['audio_file']
    print(f"{word}: {ipa} -> {audio_file}")
```

### With Hugging Face Datasets

```python
from datasets import load_dataset

# Load from Hugging Face Hub (once uploaded)
dataset = load_dataset("username/vietnamese-ipa-dataset")

# Access the data
for example in dataset['train']:
    print(f"{example['word']}: {example['ipa']}")
```

### Local Development

This project uses `uv` for dependency management:

```bash
# Install dependencies
uv sync

# Generate audio files
uv run python generate_audio.py generate

# Display dataset
uv run python generate_audio.py display

# Add new word
uv run python generate_audio.py add "xin lỗi" "sin˧˧ loj˧˩"

# Interactive example
uv run python example_usage.py
```

## Example Data

| Word | IPA | Audio File |
|------|-----|------------|
| xin chào | sin˧˧ caːw˨˩ | audio/xin_chao.mp3 |
| cảm ơn | kaːm˧˩ ʔəːn˧˧ | audio/cam_on.mp3 |
| Việt Nam | viət˧˩ˀ naːm˧˧ | audio/viet_nam.mp3 |
| nước | nɨək˧˥ | audio/nuoc.mp3 |
| yêu | iəw˧˧ | audio/yeu.mp3 |

## Considerations for Using the Data

### Social Impact

This dataset promotes Vietnamese language learning and preservation through accurate phonetic representations.

### Limitations

- Limited to 50 common words (suitable for basic applications)
- Audio generated via TTS, not native speaker recordings
- IPA transcriptions follow Northern Vietnamese dialect
- May not capture all regional pronunciation variations

### Recommendations

- For production systems, consider native speaker recordings
- Expand vocabulary for comprehensive coverage
- Add regional dialect variations if needed

## Additional Information

### Dataset Curators

Created for educational and research purposes in Vietnamese phonetics and pronunciation.

### Licensing Information

This dataset is released under the MIT License.
