it is both inconvenient and convenient as a person learning another language.
inconvenient in that it makes it sometimes more difficult to make some distinctions between spanish sounds not in english (or to not distinguish sounds distinguished in english but not in spanish)
but also convenient that probably nobody's even gonna notice how I pronounce b/v or s/z (even Sofi with zir native-level English fluency has difficulty distinguishing them when specifically listening for it)
