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

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

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:

# 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
