The Basics of the International Phonetic Alphabet (IPA)

Are you interested in expanding your language skills? Do you struggle with accurately pronouncing words in different languages? Look no further than the International Phonetic Alphabet (IPA)! This essential tool simplifies the process of learning and understanding speech sounds. Let's delve into the creation and purpose of the IPA.

What is the International Phonetic Alphabet?

The International Phonetic Alphabet, or IPA, is a collection of symbols that represent phonetic sounds. These symbols, known as phones, are used to transcribe speech sounds from various languages.

Why is the International Phonetic Alphabet so useful?

The IPA is incredibly beneficial for accurately pronouncing words. Instead of solely relying on written spelling, which may not reflect the correct pronunciation, the IPA describes the sounds of words, making it easier to pronounce them correctly. This is especially helpful for individuals learning a new language.

Who created the International Phonetic Alphabet?

The IPA was created in 1888 by French linguist Paul Passy.

How does the International Phonetic Alphabet work?

The IPA encompasses all sounds and nuances of speech in different languages, including phones, phonemes, intonation, syllables, and word separation.


Phones are distinct sounds produced during speech. They are represented in transcription between square brackets [ ].


Phonemes are the mental representations and meanings of speech sounds in a word. Changing a phoneme can alter the meaning of a word. For example, the phoneme /t/ in the word "sheet" can be replaced with /p/, changing the word to "sheep." Unlike phones, phonemes are specific to each language and are written between slashes / /.


Intonation refers to the variations in pitch when speaking. It can convey emotions, differentiate between statements and questions, indicate the completion of a sentence, and emphasize specific parts of a sentence, altering its meaning slightly.


Syllables are units of language that consist of a vowel sound and sometimes consonants. The IPA also indicates breaks between syllables.

The IPA chart displays all sounds and qualities of speech through a system of representative symbols, making it an indispensable tool for language learners.

An Overview of the International Phonetic Alphabet (IPA)

The International Phonetic Alphabet, or IPA, is a system used to transcribe speech sounds. It is divided into five main categories:

  • Pulmonic consonants
  • Non-pulmonic consonants
  • Vowels (monophthongs and diphthongs)
  • Suprasegmentals
  • Tones and word accents

Pulmonic Consonants

Pulmonic consonants are produced by air pressure from the lungs and the blockage of the space between the vocal cords. All consonant sounds in English are pulmonic. However, some other languages have non-pulmonic consonants. Pulmonic consonants can be classified in three ways on the IPA chart:

  • Voicing - whether or not the vocal cords vibrate
  • Place of articulation - where in the mouth sounds are made
  • Manner of articulation - how speech organs are used to produce the sound

For instance, the sound /b/ is a voiced bilabial plosive - meaning the vocal cords vibrate, both lips are pressed together, and the vocal tract is blocked before air is pushed out through the lips.

Non-Pulmonic Consonants

Non-pulmonic consonants are produced without airflow from the lungs. This category includes ejectives, implosives, and clicks. These types of consonants do not exist in English but are present in languages like Khoisan, where clicks are represented by symbols like ǃ and ǂ.


Vowels are sounds made without any restriction of airflow, with the sound dependent on the position of the mouth and tongue. Monophthongs and diphthongs are two categories of vowels:

  • Monophthongs - single sounds in a syllable
  • Diphthongs - two sounds in a syllable (also known as gliding vowels)

For example, the word 'hit' contains the monophthong /ɪ/, while the word 'play' has the diphthong /eɪ/. By mastering the IPA, you can accurately pronounce these and countless other words in different languages.

The Importance of Suprasegmentals in Understanding Speech

Suprasegmentals play a significant role in indicating the prosodic features of speech, including stress, tone, duration, syllable breaks, and linking. These symbols provide important clues to the meaning and intonation of a word or utterance.

Identifying Tones and Word Accents in Languages

Some languages, like Chinese, Thai, and Vietnamese, are tonal and use tones and accents to change the meaning of a word. The International Phonetic Alphabet (IPA) has symbols specifically designed for these tonal languages.

Understanding Diacritics in Phonetic Transcriptions

Diacritics are marks added to phonetic characters to show slight variations in pronunciation. They are essential in accurately representing speech sounds, such as the audible release of air in the word 'pen', which can be shown with the diacritic [ʰ] as [pʰen]. A table listing all diacritics and their meanings can be found on the IPA chart.

The Versatility of IPA Sounds

The IPA chart contains symbols for all possible speech sounds, not just those found in English. These sounds can be divided into phones and phonemes, which are further explained below.

Using Square Brackets for Phonetic Transcriptions

When transcribing specific speech sounds, phones are written between square brackets [ ]. This form of transcription is known as 'narrow transcription' and provides a detailed and precise representation of speech sounds.

Some examples of narrow transcriptions are:

  • Pin - [pʰɪn]
  • Wing - [wɪ̃ŋ]
  • Port - [pʰɔˑt]

These narrow transcriptions follow the guidelines of British Received Pronunciation.

Diacritics, such as [ʰ] and [h], are used in narrow transcriptions to indicate specific differences in pronunciation, such as aspiration and nasalisation.

On the other hand, phonemes are represented by symbols within slashes / / in broad transcriptions. Phonemes are the mental representations of speech sounds and are part of the International Phonetic Alphabet (IPA). Broad transcriptions focus on the overall sound rather than specific variations and are therefore, referred to as 'broad transcriptions'.

Some examples of broad transcriptions are:

  • Pin - /pɪn/
  • Wing - /wɪŋ/
  • Port - /pɔːt/

Broad transcriptions do not require diacritics as they focus on the general sound rather than specific nuances.

Exploring the International Phonetic Alphabet (IPA)

The International Phonetic Alphabet (IPA) was introduced in 1888 by French linguist Paul Passy. It consists of symbols that represent all possible speech sounds from all languages, providing a universal means of transcribing and pronouncing words accurately.

IPA symbols represent individual speech sounds, while phonemes are written within slashes in the IPA chart. The chart is organized into sections for pulmonic consonants, non-pulmonic consonants, monophthongs, diphthongs, suprasegmentals, tones and word accents, and diacritics.

The English Phonemic Alphabet

The English Phonemic Alphabet chart is specific to the English language and consists of 44 phonemes. Each phoneme has its own unique symbol in the IPA, making it a valuable tool for transcribing and pronouncing words accurately in English.

In conclusion, the International Phonetic Alphabet (IPA) serves as a crucial tool in understanding and accurately representing speech sounds in any language. Phonetic transcriptions use diacritics and provide a more detailed representation, while phonemic transcriptions are broader and do not require diacritics. Since its creation in 1888, the IPA has continued to be the standard for phonetic transcriptions, helping individuals to effectively communicate and comprehend words in different languages.
