◉ Consonant.
Answer: A speech sound produced by obstructing the flow of air
through the vocal tract.
◉ Vowel.
Answer: A speech sound produced without significant constriction
or closure of the vocal tract.
◉ Stops.
Answer: Consonant sounds produced by one push of breath and
then stopping the air, including /p/, /b/, /t/, /d/, /k/, and /g/.
◉ Nasals.
Answer: Consonant sounds produced with the nasal passage open,
allowing air to escape through the nose, including /n/, /m/, and
/ng/.
◉ Fricatives.
, Answer: Consonant sounds produced by forcing air through a
narrow opening or passage in the vocal tract, creating friction, this
includes /f/, /v/, /s/, /z/, /sh/, /zh/, and /th/.
◉ Affricatives.
Answer: Consonant sounds that begin as stops but are released as
fricatives, which involves a brief stoppage of airflow followed by a
slow release with friction, such as the sounds /ch/ and /j/.
◉ Glides.
Answer: Consonant sounds that glide immediately into vowels,
which includes /h/, /w/, and /y/.
◉ Liquids.
Answer: Consonant sounds characterized by a partial closure of the
vocal tract, allowing for the relatively free flow of air, like /l/ and /r/.
◉ Voiced.
Answer: Sounds produced with vibration of the vocal cords.
◉ Unvoiced.
Answer: Sounds produced without vibration of the vocal cords.
