Vowel
A vowel is a speech sound produced without significant obstruction of airflow or a written symbol representing such a sound.

A vowel is a speech sound or alphabetic letter produced without significant obstruction of airflow, including a, e, i, o, and u in this context.
- How it is used
- Uses vowels to select English articles and drive command-line string transformations.
- How deep it goes
- Explains indexing, case normalization, membership tests, conditional expressions, and replacement, while deferring pronunciation-aware rules.
- Examples
- Demonstrates narwhal, octopus, uppercase input, article selection, vowel substitution, consonant filtering, and rhyming-word generation.
- What you can do after
- Build it from scratch as a tested Python program that classifies initial letters, selects articles, or replaces vowels in text.

A vowel sound is a speech sound articulated with an open vocal tract and functioning as the vocalic nucleus of a syllable.
- How it is used
- Uses vowels to drive Pig Latin conditions and character-by-character Ubbi Dubbi translation.
- How deep it goes
- Defines vowels through five letters and works through membership tests and repeated string transformations, stopping short of phonetics.
- Examples
- Demonstrates vowels with milk, program, octopus, elephant, soap, air, eat, python, and computer.
- What you can do after
- Build it from scratch by testing vowel membership and writing string translators that branch or insert text around vowels.
