        That's the sort of thing I was thinking of. Whatever common
        conventions we use in email to denote emphasis, pauses, inflections,
        etc, should be recognized by the 'speech transfer' system. I
        consider that to be the limit of what's necessary for text input.
        The speed of text-based communication versus voice-based
        communication is going to be very noticeable. Text is a fallback
        that I hope most players will not want to use.

        Yup. Including any number of 'emotes' that people might put into
        their normal written text. Such as: <shrug>

        Absolutely necessary.

        Well, I'll take what I can get. I actually don't care about text
        output at all, but I include it in discussions as a transitional
        element. Current games use text.

        You know users. What's new doesn't always get the thumbs up.

        As before, I want speech in and speech out. I keep including text
        in the requirements for compatibility.

        Ideally, it's perfect fidelity to the speaker's voice. Eventually,
        I want the capability for video phone conferencing. Here, I'm
        thinking of more than just games and start to consider commercial
        collaborative actions in a virtual space. But in the short-term, I
        take what I can get. I took the phoneme approach to be a sort of
        compact textual equivalent with more information. As bandwidth
        increases, compressed audio would be used for the player-to-player
        audio anyway.
        
        I guess at this point, I have to ask myself: What is the phoneme
        approach bringing to the table?

        I assume the rest as idealized black boxes becuase I don't know the
        technology. I'm an engineer myself, but this is hardly my area of
        expertise. You know how marketing guys work. They just assemble
        their wish list. It's up to us to educate them as to the real
        possibilities.

        Ah, my education begins. It seems that the requirement of voice
        output is far more tractable than a requirement of voice input.
        Voice output can use a headset to ensure that the player is the only
        one who hears the output. Voice input is rather more difficult to
        manage such that only the computer hears what the player is saying.
        So text output is the least critical capability.

        Heh. DSMs typically don't even exist for mainstream applications,
        let alone games. Methodology is such a new concept for software
        'engineers'. While not exactly nascent, MMORPGs certainly have a
        long ways to go and are evolving all the time. That's a separate
        debate that lots of folks weigh in on regularly.
