Aspirated consonant

Aspirated consonants are sounds we make when we push out a strong burst of air while saying certain letters. This often happens with the sounds "p," "t," and "k" at the start of words in English, such as in "pin," "top," and "kick." In these words, the burst of air helps us tell these sounds apart from their softer versions.

In phonetics, aspiration means this strong burst of breath that happens when we let go of some sounds called obstruents. This feature is not just for English; it is important in many languages around the world.

In English, aspirated and unaspirated sounds are just different ways to say the same letter, and they do not change the meaning of a word. But in some languages, this difference matters a lot. In many North American languages, South Asian languages, and East Asian languages, whether a consonant is aspirated or not can change the meaning of a word completely. Knowing about aspiration can help when learning and speaking these languages.

Transcription

In the International Phonetic Alphabet (IPA), aspirated consonants are written with symbols for voiceless consonants followed by the aspiration modifier letter ⟨◌ʰ⟩. For example, ⟨p⟩ stands for a voiceless sound, and ⟨pʰ⟩ shows an aspirated version of that sound.

Voiced consonants are rarely aspirated. Symbols like ⟨bʰ⟩ usually mean consonants spoken with a special breathy voice instead of true aspiration. In some languages, such as Sanskrit, aspirated consonants have special names depending on whether they are voiced or voiceless.

Phonetics

Voiceless consonants are made when the vocal folds are open and not vibrating. Voiced consonants are made when the vocal folds are closed and vibrating (modal voice).

When a voiceless consonant is released, sometimes a burst of air follows. This is called aspiration.

In some languages, like Navajo and Eastern Armenian, this aspiration can change the meaning of words. In Eastern Armenian, aspirated consonants can appear at the end of words or in clusters of consonants. In other languages, such as Wahgi, aspiration only happens when consonants are at the end of words.

Phonology

Aspiration is a strong burst of breath that happens when we say certain sounds. In English, this burst helps us tell apart similar sounds. For example, most English speakers use aspiration when they start a word with a sound like "p" or "t," such as in "pin" or "top." But in other languages, like Mandarin Chinese, this burst of breath can change the meaning of a word completely.

Some languages, such as Armenian, Burmese, and Korean, use aspiration to create different meanings between words. Other languages, like French, Spanish, and Italian, don’t use aspiration at all when making their sounds.

Examples

Chinese

Standard Chinese (Mandarin) has sounds made with a strong burst of breath, called aspiration. For example, it has pairs like /t/ and /tʰ/. In writing, this is shown using different letters: d stands for /t/, and t stands for /tʰ/.

Wu Chinese and Southern Min have an even more detailed system, with three types of sounds: aspirated, unaspirated, and weakly voiced sounds. These weakly voiced sounds change the pitch of the syllable they start.

Indian languages

Many Indo-Aryan languages have sounds with aspiration. Sanskrit, Hindustani, Bengali, Marathi, and Gujarati have four types of sounds: voiceless, aspirated, voiced, and voiced aspirated. Other languages like Telugu, Malayalam, and Kannada also have aspirated sounds, mostly in words borrowed from other languages.

Armenian

Most forms of Armenian have aspirated sounds. Classical and Eastern Armenian have three types of sounds: voiceless, aspirated, and voiced. Western Armenian has two types: aspirated and voiced.

Greek

Ancient Greek had three types of sounds, similar to Eastern Armenian. Later, these sounds changed in Medieval and Modern Greek. Cypriot Greek has special aspirated sounds formed from repeated consonants.

Other uses

The term aspiration can also describe a sound change where a consonant becomes weaker, turning into a glottal stop or a fricative sound.

Main article: Breathy voice

Voiced aspirated consonants are usually spoken with what is called a breathy voice. This is a special way of making sounds where the vocal folds vibrate differently. For example, in some Indo-Aryan languages, the sound written as ⟨bʰ⟩ is better represented as ⟨b̤⟩ or ⟨bʱ⟩, showing this breathy voice quality. Some experts use different symbols for vowels, nasal sounds, or consonants.
