B vs V

bat vs vat: hear and say the difference

bat and vat are identical except for one sound: bat has the b sound, /b/, and vat has the v sound, /v/. B closes both lips completely and pops them open; V never closes anything — the top teeth rest on the bottom lip and the air keeps moving.

Who merges this

Why this pair is hard

Spanish spells both letters but pronounces one sound, so 'berry' and 'very' are the same word until the teeth touch the lip. Bengali, Japanese and Korean have no v and use b. Hindi, Urdu and Gujarati have a single v-w sound, so the contrast with b is there but the V itself is soft.

Your ear. If you cannot reliably hear which word was said, your mouth has no target to aim at, and drilling produces a sound you cannot check. Run the listening test on this page until you are scoring four or five out of five, then record the pair.
