Sonic Visualiser (http://www.sonicvisualiser.org/) can do this with
remote control via OSC, but (a) its visualisation may be overkill, at
least if you are transcribing speech rather than music, and (b)
setting up OSC control for it is a bit of a project in itself.

There is a small program (sv-osc-send) in the data/osc directory of
the Sonic Visualiser distribution which can be used to send an OSC
command to any program; there is also a shell script (sv-command)
which tries to look up the Sonic Visualiser OSC port and send your
command to the right place; and there is a rather convoluted example
remote-demo script for SV using OSC -- but none of these are provided
with any of the SV binary packages, you need the source package or
repository checkout.  Also, for any of this to work, your copy of SV
must have been built with OSC support in the first place (it is
optional).
