Which IPA symbol represents the voiceless alveolar plosive?

• A. /t/
• B. /d/
• C. /k/
• D. /s/

Answer: (A)

Understanding how voicing, place of articulation, and manner define a voiceless alveolar plosive. This sound is produced by pressing the tongue against the alveolar ridge to completely block the flow of air, then releasing it with a brief burst while the vocal cords are not vibrating. The IPA symbol for this articulation is /t/, as heard in the word “top.” The other options don’t fit: /d/ is the same place and manner but voiced, so the vocal cords vibrate; /k/ is a similar stop but at the velar place of articulation (back of the mouth); /s/ is a voiceless alveolar fricative, which involves continuous airflow rather than a burst.
