      I didn't think about that. Hmm... this begs the question of how
      much onus we put on the player to encode their own text.
      
      In one way, we can attempt to use heuristics to infer that "YOU" is
      spoken with an emphasis instead of saying it as "you" or "Y.O.U.".
      I think that's rather difficult because it requires that YOU be
      placed into the context of the sentence. Just the fact that it is
      capitalized doesn't mean it should get inflection, otherwise IBM
      would sound really weird :)
      
      This draws a close analogy to the problems in hand-writing
      recognition. Taking a cue from the PalmOS graffiti, perhaps users
      can be expected to utilize standardized tags. "How are *YOU*
      today?" Some people already type it like this for emphasis. Other
      encoding flags such as "-" or "..." could be used to denote pauses
      as well. In essence, these tags need not be the same as the tags
      used internally by the TTS. More likely, they would be meta-tags
      which encompass a way of speaking, rather than the mechanics (i.e.
      volumn, pitch) of the phonemes.
      
      As a slight tangent, the text input can also expand oft-used
      acronyms such as rotfl or lol.
      
      Note that the default TTS would tend to have some built-in
      heuristics that seem to be common. For instance, the L&H TTS engine
      currently puts your standard raised inflection when it encounters a
      question mark at the end of an input stream.

      Ah, that's the rub. At least with the phoneme method. The
      difficulty that most STT encounter is in that final stretch where
      you determine what string of phonemes can constitute a word - or
      more precisely, which word. What I'm prescribing is more like STP
      (speech to phoneme). So, at least in the near future, where
      processing capability is still growing, we may need to restrict the
      output to speech only. Like the old days of TV before close
      captioning became available.
      
      That is of course, if players would forgo that option in exchange
      for speech capability.

      Had the player been required to encode all the inflections into the
      text stream, then yes, it would fail that requirement. However,
      this is where the default heuristics in the TTS engine would kick in
      - which does a decent job. So for most sentences, it's able to
      automatically add the required correct inflections. It's just for
      the special cases such that you outlined above where the current
      heuristics fail.
      
      As for the expressive quality of the standard TTS, it will sound
      rather bland or dead pan after a while because everyone is talking
      exactly the same way. If everyone used text as the primary method
      of input, it might seem like we walked into a bad voice actor's
      convention. That's why I made the comment about encoding more tags.
      It's not required for basic communication on the order of what we
      currently have with text, but it does help in breaking up the
      monotony. And hence the suggestion that be included in the
      speech->phoneme decomposition.

      Interesting. How close to your own voice does it need to be for the
      player to player communication? I fully understand that using a
      speech->phoneme->speech method isn't a full reproduction of your
      voice, so would it be enough that it has the same patterns and
      somewhat same tone as your voice? It might be similar to trying to
      establish a conversation on a noisy telephone line - it says it's
      Bubba, and it sounds kinda like Bubba, but is it really Bubba? You
      can tell at least that it's definitely not Buffy.

      Perhaps I'm too much of an engineer, but I see no value in giving
      treatment to only the initial conceptual stage of a design and
      assuming the rest as idealized black-boxes. Sure, design
      requirements drive implementation. However, implementation
      possibilities often drive the softer design requirements. A lot of
      design focuses on determining just what the limits of these
      black-boxes impose on the overall design and the tradeoffs
      associated with it.
      
      So in the case of phonemes, the limits it imposes is that it allows
      for decent generation of tag data for the speech engine, but at the
      cost of not being able to display text on the recipients' side.
      That's an awful strong limit if your design has a hard requirement
      to give the recipient the choice between the output as either text
      or speech. Same type of limits can be derived from RDBS and OODB
      foundations and do impact design downstream (and to a lesser extent,
      upstream).
      
      Speaking of which, anyone have a good design structure matrix (DSM)
      for MMORPGs? Or is this too nascent or wide a field for one to
      exist?
