Bed Isn't the Vowel in Day

In Spanish, the vowel 'e' is always a single, pure sound — the one you hear in 'mesa' or 'pelo'. English, though, splits that space into two separate vowels: a pure, short one (as in 'bed', 'said', 'head') and a gliding one that moves toward a tiny 'y' sound (as in 'day', 'say', 'made'). Because your ear is used to just one Spanish 'e', you may stretch 'bed' into something closer to 'bayed', or flatten 'day' into something closer to 'deh'. Try this pair out loud: 'bed' — short, flat, no glide — versus 'bade' — longer, with a little lift at the end. Then try 'said' versus 'sayed', or 'test' versus 'taste'. Record yourself saying both words in each pair and listen for whether the vowel moves or stays still. Two minutes of this contrast drill daily will train your ear to hear — and then produce — two separate vowels where Spanish only ever needed one.
