The document discusses the stop consonants /t/ and /d/. It explains that both are produced with the tongue contacting the alveolar ridge in a lingua-alveolar manner, but /t/ is voiceless while /d/ is voiced, meaning the vocal cords vibrate only for /d/. The key difference between the two consonant sounds is whether vocal cord vibration occurs during articulation.
