Want to stop, “Would you repeat that, please?”
Easy!
Articulate each word completely, especially the final consonants. Record yourself speaking at work. Is each word articulated fully? Ask a friend to listen and highlight words you could improve. Why? I applaud you for speaking multiple languages and know you can fine-tune this one.
Speak much slower than you want to! Your mind gives you ideas 4-times faster than you should speak. Note: I don’t like to speak slower, either, but I do so listeners can absorb my ideas better.
Are your children correcting your pronunciation? Ask them to coach you on One Word at a time: make it a game to use that word with them for 2 days. Make it Fun, not criticizing. This is good for you and great for building their self-esteem by teaching something they know with their parent.
Are you good at your job? Don’t let pronunciation delay your success.
