Vietnamese AI Training Datasets
Master the tonal complexity of the Vietnamese language. We provide high-fidelity speech and text corpora engineered to capture the precise phonetic distinctions between Northern, Central, and Southern regional variants.
Tonal Speech Corpora
High-fidelity ASR recordings meticulously annotated for 6-tone (Northern) and 5-tone (Southern) realizations.
Regional Lexicons
Extensive NLP datasets capturing the significant vocabulary differences between Hanoi, Hue, and Ho Chi Minh City.
Image & CV
Visual data mapping Vietnamese urban environments, signage, and OCR for heavily diacriticized Chữ Quốc Ngữ text.
Bilingual Translation
Professional parallel corpora for Vietnamese-English, mapped for structural and grammatical differences.
Vietnamese Linguistic Coverage
We map the phonetic and lexical landscape of Vietnam with granular datasets for major regional variants and tonal systems.
NORTHERN VARIANT
Hanoi Standard (Tiếng Hà Nội)
Comprehensive speech corpora capturing the 6-tone system and specific consonant realizations of the Northern prestige dialect.
SOUTHERN VARIANT
Ho Chi Minh City (Tiếng Sài Gòn)
Extensive datasets reflecting the 5-tone merger, vocabulary shifts, and rapid speech patterns of the Southern dialect.
CENTRAL VARIANT
Hue & Central Coast
Specialized datasets covering the distinct phonology, vocabulary, and heavier tones of Central Vietnamese dialects.
CODE-SWITCHING
Vietnamese-English Mix
Natural conversational datasets capturing modern urban code-switching (Vinglish), essential for contemporary AI assistants.
