My favorite instruction: "Do not listen to me, listen only to the interpreter." The brain cannot process two inputs at once.
· Speak at your normal speed, long pauses confuse the witness, he or she perceives the pause as meant for him or her, not the interpreter, and will start answering through your mid-sentence pause.
· If need a court certified interpreter, make sure you say "court" when you place the order, not just certified, as there are several levels of certification.
· To avoid future issues, get the certification number on the record.
When you hire an interpreter, ask about years of experience, the California test has changed, for the last couple of years the standards have dramatically dropped so make sure you hire someone who has been certified for several years.
interpreters carry simultaneous interpreting equipment, it makes for a much better and fluid hearing, ask if it is available.
