Articulatory features: Place, manner, and voicing of sounds
Articulatory Features: Place, Manner, and Voicing
Articulatory features are the characteristics of a speech sound that are determined by the way it is produced in the vocal tract. These features can be classified into three main categories: place of articulation, manner of articulation, and voicing.
Place of Articulation
This refers to the point in the vocal tract where the sound is produced. Common places of articulation include:
- Labial: Sounds produced with the lips (e.g., /p/, /b/, /m/)
- Dental: Sounds produced with the teeth (e.g., /θ/, /ð/)
- Alveolar: Sounds produced with the alveolar ridge (the bony ridge behind the teeth) (e.g., /t/, /d/, /n/, /s/, /z/)
- Palatal: Sounds produced with the hard palate (the roof of the mouth) (e.g., /ʃ/, /ʒ/, /j/)
- Velar: Sounds produced with the soft palate (the back of the roof of the mouth) (e.g., /k/, /g/, /ŋ/)
- Glottal: Sounds produced in the glottis (the opening between the vocal cords) (e.g., /h/)
Manner of Articulation
This refers to the way in which the airflow is obstructed in the vocal tract. Common manners of articulation include:
- Stop: The airflow is completely blocked (e.g., /p/, /b/, /t/, /d/, /k/, /g/)
- Fricative: The airflow is partially obstructed, creating a hissing or buzzing sound (e.g., /f/, /v/, /θ/, /ð/, /s/, /z/, /ʃ/, /ʒ/, /h/)
- Affricate: A combination of a stop and a fricative (e.g., /tʃ/, /dʒ/)
- Nasal: The airflow is released through the nasal cavity (e.g., /m/, /n/, /ŋ/)
- Liquid: The airflow is partially obstructed, but there is a clear release of air (e.g., /l/, /r/)
- Glide: The airflow is smoothly released (e.g., /j/, /w/)
Voicing
This refers to whether the vocal cords are vibrating during the production of the sound. Sounds can be voiced or voiceless.
- Voiced: The vocal cords are vibrating (e.g., /b/, /d/, /g/, /z/, /v/, /ð/, /ʒ/, /m/, /n/, /ŋ/, /l/, /r/, /j/, /w/)
- Voiceless: The vocal cords are not vibrating (e.g., /p/, /t/, /k/, /s/, /f/, /θ/, /ʃ/, /h/)
By understanding these articulatory features, you can better analyze and describe the sounds of a language.
