The /b/ sound words are baby, ball, bat, book, boat, banana, bear, bed, bee, bell, bird, black, bone, bottle and boots. Begin by showing the child how to produce the “b” sound with a visual cue by placing your lips together, and then releasing them with a puff of air. The /b/ sound is a voiced bilabial plosive, which means that it is produced by briefly stopping the airflow from the lungs using both lips (bilabial) and then releasing it in a sudden burst (plosive). Practicing with our free online interactive audio sound cards can be a useful tool for improving pronunciation and vocabulary.
