Emotion in voices helps capture the listener's attention, but in the long run the words are not remembered as accurately. Does the emotion in our voice have a lasting effect? According to new research, emotion helps us recognize words quicker and more accurately straight away. In the longer term however, we do not remember emotionally intoned speech as accurately as neutral speech. When we do remember the words, they have acquired an emotional value; for example words spoken in a sad voice are remembered as more negative than words spoken in a neutral voice.
