First, hear how “do you” reduces to /ʤə/, because it’s unstressed. The next interesting point is the “t” at the end of “want”. Because it’s followed by /ð/, we pronounce it in the same position, with the tongue touching the top teeth. Remember; don’t remove your tongue between the two sounds. The next thing is the link between “good/bad” and “news”. Both “good” and “bad” end with /d/, which is pronounced with your tongue in the same place as /n/, so again, don’t remove your tongue between the sounds. Keep in the /d/, and release the air through your nose, making the /n/. This can take some practice.
Most people ask for the bad news first, but I’ve noticed people usually lead with good news, then say “but…” I hope you get some good news with no buts today.
