Some time ago I go to a small city of my country (vacations) .
I plain to map this for openstreetmap .( there are a blank area)
This  city don't have good images from yahoo then I only can use
gps traces from my Neo . I use voice recording for this job. When
I return to home I join a lot o files and do the work. I can tell
you some conclusions about using voice recording for mapping. 

1) I drive my car and tap my Neo to set a POI ( point of intererest ) .
But there is no map at all from the zone then I put a POI in ever cross
of ways and I need to record (voice) the name of the streets and other
info. This work needs a separate screen with only a big button because
we can check the screen to often.
2) While I seting POIs tapping my neo I recording a big wav , but when I
return to home I need to correlate this info with my GPS traces.Second
recomendation : put full date and time to the filename of voice
recording to better correlation including SECONDS.
3) I allway record my gps traces because  I put this on inittab :
gp2:2345:respawn:/usr/bin/cgpxlogger -i 1 > `date +/home/root/gps-%Y%m%d
%H%M%S.gpx | tee /var/run/gpslog`
But when I put all info into the openstreetmap editor (JOSM) the
starting time from .gpx and .wav are different and I need to make
adjustments . It's a lot more easy if we start at same time the
recording of both info. I put a killall cgpxlogger when I start the
recording of voice beacause in my config the process restart.
3b) additionally to previous recomendation if we don't  have a GPS fix
when we start to recording then we have problems later so check this
before start an inform.

I can check monologue because I make my try before but I like it.

Saludos , Jorge
