Phonetics and Phonology - IPA

🧩 How Are Consonants Classified in Phonetics? 🗣️📚

In articulatory phonetics, consonants are classified using three key features:

🔹 1. Place of Articulation – Where the sound is produced

This refers to which parts of the vocal tract come together or get close to each other.

👉 Examples:

Bilabial: /p/, /b/, /m/ – lips come together (e.g., pat, bat, mat)

Alveolar: /t/, /d/, /n/, /s/, /z/ – tongue touches the alveolar ridge (e.g., tap, zip)

Velar: /k/, /g/, /ŋ/ – back of tongue touches the soft palate (e.g., cat, go, sing)

🔹 2. Manner of Articulation – How the sound is produced

This describes how air flows through the vocal tract and how it's modified.

👉 Examples:

Stops (Plosives): /p/, /t/, /k/ – air is stopped and released (like a pop)

Fricatives: /f/, /v/, /s/, /z/ – air passes through a narrow gap causing friction

Nasals: /m/, /n/, /ŋ/ – air flows through the nose

🔹 3. Voicing – Whether vocal cords vibrate

This is about whether your vocal folds are vibrating during the articulation.

👉 Examples:

Voiced: /b/, /d/, /g/, /v/, /z/ – vocal cords vibrate

Voiceless: /p/, /t/, /k/, /f/, /s/ – vocal cords do not vibrate

🧠 You can feel the difference by placing your hand on your throat:

Say /s/ (voiceless), then /z/ (voiced) – feel the vibration? That’s voicing in action!

🎯 So when linguists describe a sound like /b/, they call it a:
Voiced bilabial stop

And /s/?
Voiceless alveolar fricative

🗣️ Consonant classification helps us understand accents, pronunciation, and even speech disorders.

🎙️ The 3 Branches of Phonetics – Explained with Examples! 🧠👄🎧

Phonetics is the scientific study of speech sounds, and it's divided into three main branches, each with its own focus and method of analysis:

🔹 1. Articulatory Phonetics – How we produce sounds

This branch looks at how speech sounds are made by the movement of our speech organs such as the tongue, lips, teeth, and vocal cords.

👉 Example:

When you say /t/ as in “top”, the tongue touches the alveolar ridge (just behind your teeth).

Try saying /m/ as in “man” – your lips come together and sound resonates through your nose (a nasal sound).

🧠 It’s all about what your mouth and vocal tract are doing!

🔹 2. Acoustic Phonetics – How sound travels

This branch studies the physical properties of sound waves – things like frequency, duration, and amplitude.

👉 Example:

The vowel /i/ (as in “beet”) has a higher frequency than /u/ (as in “boot”).

These differences can be seen using a spectrogram – a visual display of sound waves.

📊 This is the most technology-based branch, using tools to measure and visualize sound.

🔹 3. Auditory Phonetics – How we perceive sounds

Here, the focus is on how we hear and understand sounds – including how the ear processes them and how the brain interprets them.

👉 Example:

In English, /l/ in “light” and “feel” are acoustically different, but most native speakers don’t notice – this is due to perceptual categorization.

👂This branch is crucial in speech therapy, language learning, and audiology.

✨ These three branches work together to give us a full picture of how speech sounds work – from the speaker’s mouth to the listener’s brain!

🎙️ Phonetics vs. Phonology: What's the Difference? 🧠👂

Ever wondered what sets phonetics apart from phonology? 🤔

🔹 Phonetics is the study of actual sounds of speech – how we produce them, how they travel, and how we hear them. It’s all about the physical side of sound.

🔹 Phonology, on the other hand, looks at how sounds function in a particular language. It's about the rules and patterns that govern pronunciation in different languages.

🗣️ Example: The [p] sound in spin vs pin – phonetically different (aspirated vs unaspirated), but phonologically the same in English!
