Linguistics // Speech Sounds

PHONOLOGY &
PHONETICS

The study of the cognitive organization of sounds (phonology) and their physical production and perception (phonetics). It is the bridge between human thought and the acoustic waves we push through the air.

Phonemes vs. Graphemes

A grapheme is a written letter (like "c"). A phoneme is an atomic unit of sound. English is notoriously terrible at mapping graphemes to phonemes.

The letter "c" sounds completely different in the words "cat", "cell", and "choir". Conversely, the exact same sound can be spelled differently, as in "to", "too", and "two".

To study linguistics scientifically, we must abandon spelling entirely and look only at the underlying acoustic data.

IPA and ARPAbet

The International Phonetic Alphabet (IPA) was created to give every single distinct sound humans can make its own unique symbol.

However, because standard computer keyboards lack characters like /ʃ/ or /ð/, computer scientists developed the ARPAbet in the 1970s. It represents phonemes using standard ASCII characters, making it the backbone of text-to-speech engines and pronunciation APIs.
