All, Just learned about Multipsk's "Voice" mode thanks to Sholto (KE7HPV). It's an Olivia mode derivative that uses 8 tones with a bandwidth of 168 Hz. It's called Voice because it has the ability to vocalize incoming characters.
I'm sure Patrick developed the mode with sightless hams in mind and I thought I'd mention it here since I believe there are a few sightless hams on this reflector. It might be an undertaking, but it would seem that this could be taken a step further by linking the incoming digital mode text to a text-to-speech program or something along those lines. That would allow speech with any mode. Just a thought. Tony, K2MO
