I don't personally find a need for digital voice communications on HAM. Analog is perfectly fine. You get much more reliability and stability from analog voice.

There's not really a rush to move away from it, especially on HF. Digital voice unless in a stable environment or with multiple expensive tower sites, you'll be dropping packets and not be able to either make out a conversation as you get scambled robot voices, or simply dont decode it at all. Analog, you can still pick voices out of deep noise and some people are very very good at analog low signal reception with their ears/brain in combination with the receiver. It's also nearly impossible to get huge bandwidth rates on HF with major fading and unpredictable communications. Non-voice digital modes are certainly innovating especially on HF, picking out signals well below the noise floor.
