Decision Making, Male Version
Filed Under (Off the Hinges) by Bogo on 14-04-2010
The following idea for a male decision making model hit me during a lazy Thursday afternoon (it’s not like I remember the day, but it must have been a Thursday since ideas such as this one can only come during that depressingly insignificant day). I was riding the bus back home, and I was thinking about the voiced speech part of a model that I had to code up for one of my ongoing projects. If you don’t care about the technical stuff or are afraid of it, skip the following text all the way until after the first diagram. Anyway, the human speechy-makie-thingy (for the lack of a better expression or the unwillingness of the author to make this post too technical or formal) basically consists of two things: the larynx, aka the “voice box” that flaps around and produces the raw sound, and the vocal tract as well as all the bunch of stuff after (tongue, lips, etc.) that shapes the raw sound into the sounds that we want to produce. The larynx flaps around like crazy with no definite pattern (pretty much like a salmon thrown on the beach of the Japanese coast by a giant tsunami caused by an earthquake which was in turn caused by a giant shield volcano eruption somewhere in the Pacific and yes I love brackets and I make them huge now go and read the first part of the sentence again since you probably forgot it and lost my train of thought) when we are using unvoices speech (letters like p, t, k, etc.), and does some periodic shit when we are using voiced speech (mostly vowels). All of this can be fit into a simple (or not so simple, I don’t know) model where the stuff that the larynx produces is simulated by either white noise (for unvoiced) or periodic impulse train (for voiced speech). Then this data is passed through a digital filter that simulates the vocal tract plus the rest of the crap after, and voila! Speech! Humanity! Evolution! I made a figure too, for those that need a kick to fire up their imagination, plus I could conveniently modify it and use it in my thesis paper one day. I just hope that nobody realises I am using the same material in my uber-official papers as well as my share-your-mental-diarrhea blog. Read the rest of this entry »
