Open Options With Audio

Greetings, 

I'm in the process of creating elearnings for my company and was asked to explore text to speech.  I've been reading previous threads about this topic but wanted to ask if the vendors were still relevant and can provide quality voices that don't sound so robotic.  Here's a few suggestions Ivona, ISpeech, Acapela Virtual Speaker.  Thoughts and other suggestions are very welcome! 

Thank you
