Final answer:
The stop phonemes /b/, /d/, /g/ are voiced, which means they are pronounced with vibration of the vocal cords. These phonemes are distinct from unvoiced stop phonemes and are used in words to create different sounds.
Step-by-step explanation:
The stop phonemes /b/, /d/, and /g/ are voiced. This means that when they are pronounced, the vocal cords vibrate. For example, when you say the sound /b/ as in 'bat', you should feel a vibration in your throat, which indicates that it is a voiced sound. The same is true for /d/ as in 'dog' and /g/ as in 'go'.
Exploring other consonant sounds and spellings, we can see how these voiced stops are used in words. In the word 'fatter', the /t/ represents an unvoiced stop phoneme, which is different from the voiced /d/. In 'opening', the /b/ is the voiced stop and 'started' also includes the voiced /d/, while 'stopping middle' uses both the voiced stop /b/ in 'middle' and the unvoiced stop /p/ in 'stopping'.
