Within the chart “close”, “open”, “mid”, “front”, “central”, and “back” refer to the placement of the sound within the mouth. [3] At points where two sounds share an intersection, the left is unrounded, and the right is rounded which refers to the shape of the lips while making the sound. [4]
The two common labial articulations are bilabials, articulated using both lips, and labiodentals, articulated with the lower lip against the upper teeth, both of which are present in English. A third labial articulation is dentolabials , articulated with the upper lip against the lower teeth (the reverse of labiodental), normally only found in ...
The extensions to the IPA also define a bilabial percussive ( ⓘ) for smacking the lips together. A lip-smack in the non-percussive sense of the lips audibly parting would be [ʬ↓]. [7] The IPA chart shades out bilabial lateral consonants, which is sometimes read as indicating

They are classified depending on the position of the tongue relative to the roof of the mouth, how far forward or back is the highest point of the tongue, and the position of the lips (rounded or unrounded).
Spectral properties are the speech sound's fundamental frequency and its formants. Each vowel in the vowel diagram has a unique first and second formant, or F1 and F2. The frequency of the first formant refers to the width of the pharyngeal cavity and the position of the tongue on a vertical axis and ranges from open to close.
