Common public speaking problems

    The use of “I feel”, “I think” and “maybe”

    In the question-and –answer session of the speaking competition, many contestants began their answers with uncertain expressions like “I feel”, “I hear”, “maybe” and “perhaps”. These words show that the person is only speaking from his or her point of view. {#blank#}1{#/blank#}

    Work on keeping your answers brief and to the point. Also work on delivering them with calmness and confidence. Instead of the empty-sounding “I guess”, using facts, together with a clear conclusion based on those facts, is far more likely to be popular with an audience.

According to a recent survey, half of the world's AI experts believe human level machine intelligence will be achieved by 2040. This will open up huge possibilities for the enrichment of mankind, from tackling climate change and treating disease to labour- saving devices.
