Phonetic character set - ‘articulate’

I am working on a character set that visually represents the way the tongue, lips, jaw, vocal cords, and other speech organs are used to make sounds (articulatory phonetics). These 46 characters (the 46 phonemes found in British English, for now), split into vowels, diphthongs, consonants, and digraphs, can be found below, along with an IPA notation, example word, and grouping for each.

I hope to make more information available on the creation and implementation of these characters here over time as they evolve.

vowels

The 13 vowels and 8 diphthongs were created by referencing mouth position (close, near-close, close-mid, mid, open-mid, open), tongue position (front, near-front, central, near-back, back), and the rounded or unrounded nature of the lips when vocalising each sound.

  • The central shape—either leaf, circle, or ellipse—represents the mouth. Leaves represent unrounded lips. Circles and ellipses, as with [uː], [ʊ], [ɔː], and [ɒ], represent rounded lips.

  • The curved or straight lines to the left and/or right of the central shape represent the tongue. A curved line to the left, as with [ɛ], means ‘front’ position, as in towards the teeth. A curved line to the right, as with [ʌ], means ‘back’ position. Lines on both sides represent a central, as with [ə], or near-front/back, as with [ʊ], position.

  • Additional arcs beneath central shapes, as with [iː], [uː], [ɜː], [ɔː], and [ɑː], represent long vowel sounds.

diphthongs

Created by combining pairs of vowel characters, as seen above.

  • In most cases, the two characters are overlaid with no changes.

  • For clarity, in [ɔɪ], [əʊ], and [aʊ], the back position tongue lines have been lengthened.

  • For clarity, in [ɔɪ] and [əʊ], the height of the leaf has been increased to match the overlaid circle.

consonants

The 23 consonants and 2 digraphs were created by referencing lip, teeth, and tongue position, as well as nasal and glottal use. These positions are compiled into two groups, as follows:

Group 1 - Bilabial, Labiodental, Dental, Alveolar, Postalveolar, Retroflex, Palatal, Velar, and Glottal.
Group 2 - Plosive, Nasal, Fricative, Approximant, and Lateral Approximant.

Each character is designed by merging two characteristics, one from Group 1 and one from Group 2.

GROUP 1

Bilabial

The upper and lower lips (half-circles) touch, as with [p], [b], and [m].

LABIODENTAL

The upper teeth touch the lower lip, with the lower lip set back, as with [f] and [v].

Dental

The tongue (a straight line in this case) touches the teeth, as with [θ] and [ð].

Alveolar

The tongue (a curved line in this case) is raised at the front, touching behind the upper teeth, as with [t], [d], [n], [s], [z], [ɹ̠], and [l].

Postalveolar

The tongue (a curved line in this case) is raised higher at the front, touching between the upper teeth and the palate, as with [ʃ], [ʒ], and the digraphs [tʃ] and [dʒ].

Retroflex

The tongue (a curved line in this case) is raised high at the front and the back, as with [ɭ].

Palatal

The tongue (a straight line in this case) pushes up against the palate of the mouth, as with [j].

Velar

The tongue (a curved line in this case) is raised at the back, as with [k], [g], and [ŋ].

Glottal

The vocal cords contribute to the sound, represented by a small circle below the teeth, as with [ʔ] and [h].

GROUP 2

Plosive

The vocal tract is blocked, causing a stop in sound. This is represented by a second verticle line to the right of the teeth, as in [p], [b], [t], [d], [k], [g], and [ʔ].

Nasal

Air flows through the nose, represented by a small circle above the upper teeth, as with [m], [n], and [ŋ].

Fricative

Air is forced through a narrow space to produce the sound, represented by a dot to the left of the lips, as with [f], [v], [θ], [ð], [s], [z], [ʃ], [ʒ], and [h].

Approximant

Air passes between the tongue and the back of the mouth, but they do not touch, represented by multiple ‘tongue’ lines, as with [ɹ̠] and [j].

lateral Approximant

Air passes between the tongue as it touches the palate, represented by multiple ‘tongue’ lines, as with [l] and [ɭ].

The combination of these two characteristics makes each character unique, just like the biological positions required to produce them. This can be seen below, where the two characteristics, as well as whether the sound is voiced or unvoiced, are noted below each character.

Digraphs

As with the diphthongs , the 2 digraphs were created by combining pairs of consonant characters, as seen above.

 

word submissions

If anyone would like me to display how a certain word looks using Articulate, please submit it via the form below, and I will (over time!) add it to the submissions gallery below. Please bear in mind that I cannot take into account your accent or pronunciation, so I will transcribe it as I would speak it myself!
