I recently misstated how the TenTec Speech Processor works, sorry.  Here it is more correctly.  The device, their model 715, listing at 249 dollars, is connected between one's mike and transceiver.  It functions by mixing the audio up to its own internal IF of 455KHz, filtering out the unwanted sideband, clipping it (level is adjustable), filtering it again to remove harmonics and mixing it back down to audio, which then goes into the transceiver's mike input.  I have one and like it, getting nice reports of audio quality from folks who are familiar with my voice face to face.  TenTec offers connecting cables for Yaesu, ICOM, Kenwood/Elecraft.
