[PD] "When the bubbles exploded, they tickled the bath."

I solved this a couple of different ways for various
projects. The rjdj "Drowning Street" had a bubble
generator (synthetic) hooked to an envelope tracker
(RMS side chain with [env~]). It works well if the
pitch centre of the bubbles are close to the voice
pitch, so you could use fiddle or sigmund to focus that.
Another "bubbling voice" thing I did used slow amplitude
and pitch modulation of the voice to create a "Dalek"
type ringmod circa 8 Hz. The vibrato effect can be done
with [vd~] taps, spaced in time and enveloped like a
bubble generator. Interestingly, some realism can 
be added if you pitch shift the voice up too, since
underwater the speed of sound is faster.
