The DMG says spell trigger items use a spoken word.
However, it has another section about specifically activating a wand that uses the same language as the SRD, i.e. no mention of spoken word.
Therefore I have concluded that Spell Trigger items require a spoken word, unless they are Wands. This also makes identification of a wand rather easy.
