1. Phonetic: This is the most accurate term, meaning "relating to the sounds of speech." However, it's a broader term and doesn't specifically refer to words that match their spelling.
2. Regular: This is often used to describe words that follow predictable spelling rules, making them easier to pronounce. However, not all regular words are pronounced exactly as written (e.g., "though" or "enough").
3. Transparent: This term emphasizes the ease of reading and understanding the pronunciation, but it's not as commonly used in this context.
4. Predictable: This emphasizes the consistency between spelling and pronunciation, but it might be too broad for words that are consistently pronounced as they are written.
5. "Words that are spelled as they sound" is a long but clear and straightforward way to describe them.
6. "Words with perfect spelling-sound correspondence" is a more technical but accurate way to describe them.
Ultimately, the best term depends on the specific context and the level of formality required.
