# Phonetics and Phonology Languages I · English Phonetics and Phonology · https://tryals.app/learn/languages-i/phonetics-and-phonology ## The Same Sounds, Two Questions **Phonetics** studies speech sounds as physical events. It examines how sounds are produced, transmitted, and perceived. It is entirely language-independent. **Phonology** studies how a particular language organises sounds into a system. It is language-specific. It asks which sound differences convey meaning. | Term | Definition | |---|---| | **Phone** | Any speech sound, as produced | | **Phoneme** | A contrastive unit of a particular language | | **Allophone** | A predictable variant of a phoneme | ### The Test: Meaning Two sounds belong to different phonemes if swapping them changes the word. This is a **minimal pair**. *Pat* and *bat* differ in one sound and meaning. This proves /p/ and /b/ are distinct phonemes in English. Allophones never distinguish words. They show two main patterns: - **Complementary distribution**: Sounds occur in mutually exclusive environments, like aspirated /p/ in *pin* versus unaspirated /p/ in *spin*. - **Free variation**: Sounds interchange in the same position without changing meaning, like a released or unreleased /t/ in *cat*. ### Systems and Inventories A phonetic difference can be allophonic in one language and **contrastive** in another. Aspiration is predictable in English, but it distinguishes words in Thai. Received Pronunciation contains **44** phonemes: - **24 consonants** (a total of 24) - **20 vowels** (a total of 20, comprising 12 monophthongs and 8 diphthongs) ### Notation Transcription reflects the phonetics-phonology divide: - **Broad (phonemic) transcription** uses slant brackets / / to record only phonemes. - **Narrow (phonetic) transcription** uses square brackets [ ] to capture fine acoustic detail. > **Common pitfall:** Thinking a phoneme is a concrete sound. A phoneme is an abstract **category** of sounds treated as identical by a language. ## Practice questions 9 of this lesson's 13 practice questions, with answers. The full set is in the app. ### 1. Aspiration is predictable in English and distinguishes words in Thai. What does this show about the phoneme? A. Acoustic properties like aspiration possess inherent phonemic status across languages B. Predictable allophonic variations eventually develop into distinct contrastive phonemes C. Phonemic status is a property of a language's system, not of the sounds themselves D. Phonetic contrasts only achieve phonemic status when occurring in free variation **Answer:** C. Phonemic status is a property of a language's system, not of the sounds themselves **Why:** That phonemic status belongs to the **system**, not to the acoustics. The same physical difference is inaudible to English speakers as a contrast and fully meaningful to Thai speakers, because English uses it to fill in a predictable detail and Thai uses it to distinguish words.

A minimal pair proves that two sounds belong to different phonemes in that language. **Answer:** True **Why:** **True**, and it is the single most useful tool in phonology. *Pat* and *bat* settle the status of /p/ and /b/ in English in one step. The converse does not hold: failing to find a minimal pair does not prove two sounds are allophones, since gaps in the vocabulary are common.

Phonetics examines physical sound, whilst phonology examines linguistic systems. What follows from this distinction when transcribing an unreleased [t̚] at the end of 'cat'? A. The feature is marked in narrow brackets to capture phonetic detail B. The sound is placed in slants because it contrasts with released [t] C. The variant requires slants to show its position in the word system D. The acoustic detail is discarded in all systems as non-contrastive **Answer:** A. The feature is marked in narrow brackets to capture phonetic detail **Why:** Confusing physical variants with contrastive units leads to misusing slants, which solely record phonemes. Free variation in allophones alters acoustic reality without creating separate lexical categories, making broad transcription deliberately omit the detail.

How many consonant phonemes are conventionally recognised in Received Pronunciation? **Answer:** 24 **Why:** **24 consonants**, against 20 vowels, 12 monophthongs and 8 diphthongs. The consonant count is stable across analyses; the vowel count is where descriptions differ, which is why General American is usually given a smaller total.

Sort each statement by whether it belongs to PHONETICS or PHONOLOGY. **Answer:** - Phonetics: This sound has a burst lasting 60 milliseconds, The tongue tip contacts the alveolar ridge, The first formant is around 300 hertz - Phonology: These two sounds never contrast in this language, This language has 24 consonant phonemes, Aspiration is predictable from syllable position here **Why:** The test is whether you would need to know the language to make the statement. A burst duration can be measured from a recording of a language you have never heard; whether that difference distinguishes words cannot.

Complete the vocabulary of the two disciplines. **Answer:** Any speech sound as produced is a **phone**. A contrastive unit of a particular language is a **phoneme**. A predictable variant of one is an **allophone**. Two sounds that occur only where the other cannot are in **complementary** distribution. **Why:** The three-term hierarchy is worth memorising exactly: a phone is a thing that happened, a phoneme is a category the language maintains, and an allophone is a phone considered as a member of a category. Most confusion in this unit comes from collapsing the second and third. Page: https://tryals.app/practice/languages-i/phonetics-and-phonology/complete-the-vocabulary-of-the-two-disciplines ### 7. Which are true of a narrow phonetic transcription? A. It can describe a language whose phonology is unknown B. It records only the contrastive units of the language C. It records detail such as aspiration and length D. It is written in square brackets **Answer:** A. It can describe a language whose phonology is unknown; C. It records detail such as aspiration and length; D. It is written in square brackets **Why:** The fourth defines broad transcription, which is the other option. The third is worth noticing: because narrow transcription records what was heard rather than what contrasts, it is what a fieldworker uses on day one, before there is any phonemic analysis to be broad about.

Match each notation or term to what it does. **Answer:** - Slant brackets → Enclose a broad, phonemic transcription - Square brackets → Enclose a narrow, phonetic transcription - Minimal pair → Establishes that two sounds contrast - Complementary distribution → Shows two sounds are variants of one phoneme **Why:** The two tools in the second half are the working method of phonemic analysis: look for a minimal pair, and if none exists, check whether the environments of the two sounds ever overlap. If they never do, you have one phoneme rather than two. Page: https://tryals.app/practice/languages-i/phonetics-and-phonology/match-each-notation-or-term-to-what-it-does ### 9. General American is usually analysed with the same number of vowel phonemes as Received Pronunciation. **Answer:** False **Why:** **False.** GA is generally given fewer vowels: it lacks RP's centring diphthongs, and many speakers have the cot–caught merger. The consonant inventories match almost exactly, which is why vowels are where descriptions of English accents diverge.
