As well as Phonaesthesia - as Uwe mentions - the construct of Phonaesthetics may be helpful - although it seems to attract a lot of work on Tolkein!!!

I'd look at the top 100 lists of baby names which the Census publishes every few years.  I think if you did a frequency count, you'd find a very high number of liquids and glides.  You might also get a sense of common stress/syllabic patterns (two syllable words, strong first syllable).

Phonotactics seem to matter...at least for hypothetical purchases.   Vitevitch & Donoso (2012) found that people indicated they'd be more likely to buy fictional products that had high probability names.
