Hi Tearing, the answer is always, since in Spanish there is no difference between them. The pronunciation of the "v" as labiodental as in other languages ​​has never existed in Spanish, and only occurs spontaneously in Valencian and Majorcan speakers and in some areas of southern Catalonia, when they speak Castilian, influenced by their regional language. Also occur spontaneously in some parts of America under the influence of Amerindian languages​​. In the rest of the Spanish-speaking area, the two letters have identical pronunciation / b /. The sound is stronger at the start of word on "Bebé", the first b is explosive, while the second is softer (voiceless). The same goes for words like "vivo". Source: elcastellano.org But as previously commented, you should focus on spelling rules to write correctly "b" and "v". I sincerely hope this helps you, Tearing. Have a nice day!

That's an easy answer: always. Unlike many other languages, in Spanish we pronounce "v" as "b".

¡Hola Tearing! Hi there Tearing! This is actually a really easy question to answer: They NEVER sound the same. "V" should be pronounced like "V" and "B" should be pronounced like "B". Even Though there is people that pronounce them the same way, it's not correct. Espero haberte ayudado. Saludos! :)

Actually it depends of where are you from, in some regions of Spain we pronounce always "v" as "v" and "b" as "b", and souns a bit weird when someone pronounce "vaca" as "baca". For example in Baleares, Cataluña and Valencia.

Buenas noticias: Actualmente no hay ninguna distinción entre "v" o "b". De hecho nunca a existido diferencia en España salvo en algunas comunidades por influencia de su lengua regional.
