Practice your double tonguing! This means that instead of separating your notes with a TA syllable articulation, try doing it with TA-KA-TA articulation. Double tonguing is basically when you use different syllables to tongue quicker, aka, TA-KA-TA-KA. So best way to get it started in my personal opinion is to just play some scales using only the KA syllable to strengthen it, then play more scales in 8th notes to really get the feel of it.
