Sound Description by Meibis M. González
Consonants and vowel sounds are described in the same way they are classified. Because of this, the following information deals with both vowel and consonant sounds.
Vowels and Consonants• Humans produce speech sounds that
are either vowels or consonants. • Vowels and consonants have a different
form of obstruction. That is, vowels are relatively unobstructed in the oral cavity, whereas consonants are produced with a complete or
partial obstruction of the airstream in the oral cavity.

Vowel Sounds
• Vowels are classified according to 1. Height 2. Backness 3. Tenseness 4. Rounding
Note: All vowels are voiced
Description of Vowel Sounds
1. Height (high, mid, and low)2. Backness (front, central,
and back)3. Tenseness (tense or lax)4. Rounding (round or spread-
unround)
Vowel Chart
Note: the “schwa” sound is located as low central for some authors. Also, the /a/ sound is located as low back for some authors
Consonant Sounds
• They are classified according to 1. Voicing (voiced- voiceless)2. Place of Articulation3. Manner of Articulation
Important: They are described following the same order above.
Place of Articulation1. Bilabials2. Labiodentals3. Interdental4. Alveolars5. Alveo-palatals ****6. Palatals7. Velars8. Glottals
Manner of Articulation
• It refers to how the sound is produced and the way in which the airstream is modified as it passes through the vocal track
Manner of Articulation
1. Stops2. Fricatives3. Affricates4. Sibilants5. Sonorants and Obstruents6. Liquids7. Nasals8. Glides
Stops
• In producing them, the air is stopped in the mouth and then released immediately.– They can be: (voiceless, voiced) Bilabial Stops /p/, /b/
• Alveolar Stops /t/, /d/• Velar Stops /k/, /g/
Fricatives
• Sounds produced by allowing the air to pass through a small passage, thereby producing friction.
Fricatives
• They are classified as:– Labio-dental fricative /f/ /v/– -Inter-dental
fricative / / / / - Glottal fricative /h/ - Alveolar fricative /s/ /z/ -Palatal fricatives / / /
Africates
It has both a stop and a fricative manner of production. The two sounds are produced so rapidly that they are heard as a unit.The two sounds in this category are: alveo-palatal sounds / / and / / The first sound is voiceless
The second sound is voiced
Nasals
• The velum is lowered so that sounds pass through the nose rather than through the mouth. The oral cavity is completely closed. All nasals are voiced.
• They are divided as–1. Bilabial Nasal /m/–2. Alveolar Nasal /n/–3. Velar Nasal / /
Liquids
• The alveolar lateral /l/ is produced by pressing the tongue against the alveolar ridge and letting the sound pass through the sides of the tongue.
Retroflex
• The retroflex /r/ is produced by letting the sound pass between the hard palate and the slightly rolled tip of the tongue
Semivowels or Glides
It is characterized by a continued, gliding motion of the articulators into the following vowel. They are also considered as semi-vowels
Bilabial Glide /w/
Palatal Glide / j /
Consonant Chart
• Important:
• Alveolo-palatal (or alveo-palatal) which have simultaneous alveolar and palatal articulation.
• In the official IPA chart, alveo-palatals would appear between the alveolar and palatal consonants
For instance, in describing /l/, the feature lateral is enough to describe this sound because /l/ is the only lateral sound existing in English
When describing a sound or a group of sounds, you should only include the features that are required to describe that particular sound or that particular group of sounds
