Of course not. Pronunciation and font are very similar, which will make consumers misunderstand. For example, "Sprite" is similar to "Rinspeed", and the latter has been investigated for infringement. However, if the meaning and pronunciation of a word are obviously different after changing, it can be passed. Trademarks should be judged on a case-by-case basis, and sometimes it's hard to say. In short, the bigger the gap, the easier it is to sign up.
