📚 Portuguese Phonetic Lexicon Dataset

This dataset contains phonetic and morphological information for Portuguese words, collected from the Portal da Língua Portuguesa. It was generated by scraping the site across multiple Portuguese-speaking regions and dialects.

The dataset includes words as spoken in ten regional variants:

• 🇵🇹 Lisbon (Standard and Non-Standard)
• 🇦🇴 Luanda
• 🇧🇷 Rio de Janeiro (Standard and Non-Standard)
• 🇧🇷 São Paulo (Standard and Non-Standard)
• 🇲🇿 Maputo (Standard and Non-Standard)

Each word is associated with its phonetic transcription and grammatical metadata.
