Fair enough, but that is one of the things that the Multimedia Messaging
System (MMS) standard is designed to overcome. You could, in theory,
send an MMS message from a cellphone to a software package that uses a
USB device driver to emulate a microphone. Many of the speech vendors
already have means to dictate from spooled audio, do they not?
Then the question becomes, how bad is MMS's Adaptive Multi-Rate (AMR)
vocodec, and there are different extents of AMR compression. Frankly,
with MMS, and the bandwidth that some of these phones operate at when
they are in data-mode, only in poor-signal areas would there be a
problem. The MMS email message signaling profile, which allows for a
kind of an "always-on, but fully spooled if off" operation, has
solutions to those problems, too.
Sincerely,
James
