（这个正确）I speak for myselfspeak for 代表…讲话，为……而说I represent myself！（此句应译为 我代表我自己）represent 英[reprɪ'zent]美[,rɛprɪ'zɛnt]vt. 代表；表现；描绘；回忆；再赠送vi. 代表；提出异议I speak of myself （此句应翻译为 我谈到我自己）有道，百度翻译结果中的speak of 应该翻译为 谈到；论及

I'mthespokesmanofmyself.代言人：spokesperson/spokesman/spokeswoman

I'm the advert for myself.
