In Jewish tradition, speaking the name was forbidden because it was so holy that people didn't dare speak it. This has been the case for centuries.
In essence, the idea has two aspects. First, it was a sign of respect, and reverence for the word, that it should not pass through unclean lips. Second, it was a fear of accidentally taking the Lord's name in vain.
There's a related question here that sheds more light on this in greater detail. it covers a question from the Catholic perspective, but traces back to the Jewish traditions.
This article states it nicely:
The avoidance of the original name of God both in speech and, to a
certain extent, in the Bible was due, according to Geiger
("Urschrift," p. 262), to a reverence which shrank from the utterance
of the Sublime Name; and it may well be that such a reluctance first
arose in a foreign, and hence in an "unclean" land, very possibly,
therefore, in Babylonia. According to Dalman (l.c. pp. 66 et seq.),
the Rabbis forbade the utterance of the Tetragrammaton, to guard
against desecration of the Sacred Name; but such an ordinance could
not have been effectual unless it had met with popular approval.

In other words, the traditional view is that using the name is less respectful. This would be the view I'd take, given the reverence that God expects from us when approaching Him.
Certainly, there are Christian groups that feel the opposite. A Google search for "don't speak the name Yahweh" returned a plethora of sites from various groups that hold that not using the name is disrespectful, and even sinful.
Some prefer to use the name because they believe out of a fear that using the words "God" and "Jesus" mean that we're referring to someone else, and almost equate using any name other than the originals at idolatry. http://newlifeonahomestead.com/2011/02/why-say-yahweh-instead-of-god-and-why-yeshua-instead-of-jesus/
Others (like this one) come to the conclusion that the meaning of God's name indicates that we are God. (That's sort of the opposite of Christianity, thought, so I don't think it counts as a "Christian" perspective.)
