Hatoyama's English Speech - A Target for Our Students?

I was introduced to this video, which I may have seen before on news, as part of participating in a survey about the intelligibility of English spoken by Japanese professionals.

Hatoyama does a good job of articulating the key words of his speech enough to make his message clear. He is reading a script for his speech (as most high level speakers do in important occasions), but he has practiced well and it meets the aim of the communication situation.

To be effective, your English doesn't have to be perfect! Also, pronunciation mistakes of a few sounds or words here and there don't affect your general ability to be understood, so mainly focus on saying your key words and phrases correctly and with emphasis.

Of course, at the same time, as an instructor of higher level public speaking skills, it is easy to notice many areas that Mr. Hatoyama needs to improve in.

He obviously did not write the speech by himself, and he is not able to pause effectively to wait for an applause after he states his most important point about Japan's commitment to reduce emissions 25%.

He needs to prepare to deliver his most important point like that with eye contact and more emphasis and pausing, stopping after every word and building up to the main point and possibly even repeating the most important phrases for emphasis.
