The team has employed sound pattern recognition approach that uses a statistical analysis of the frequency of cries and the power function of the audio spectrum to classify different types of crying. They were then able to correlate the different recorded audio spectra with a baby’s emotional state as confirmed by the child’s parents. In their tests recordings of crying babies with a painful genetic disorder, were used to make differentiating between the babies’ pained cries and other types of crying more obvious. They achieved 100% success rate in a validation to classify pained cries and “normal” cries.

I’m a new parent of twin boys, and I could really use something like this. But it would be even better if the algorithm could break down the “normal” cries into specific needs. Mr. Nagashima, you are doing God’s work; faster, please.

Perceptual chauvinism /2010/01/11/perceptual-chauvinism/ /2010/01/11/perceptual-chauvinism/#comments Tue, 12 Jan 2010 03:20:42 +0000 Dave /?p=3805 I read two articles in a row today that use unnecessary quotation marks, which expose that strange discomfort with writing about touch I have written about before. As humans we hold our feelings dear, so we don’t like to say that any other beings can feel. Especially plants, for chrissake:

Plants are incredibly temperature sensitive and can perceive changes of as little as one degree Celsius. Now, a report shows how they not only “feel” the temperature rise, but also coordinate an appropriate response—activating hundreds of genes and deactivating others; it turns out it’s all about the way that their DNA is packaged.

The author can’t simply say that plants can feel, so instead he writes “feel,” indicating a figurative sense of the word. Why? Because the word ‘feel’ implies some amount of consciousness. (In fact I have argued that ‘feeling’ signifies a baseline for the existence of a subject.) Only the animal kingdom gets feeling privileges.

And then, in another article posted on Science Daily, we have a similar example, but this one is even more baffling. The context is that research has shown that playing Mozart to premature infants can have measurable positive effects on development:

A new study… has found that pre-term infants exposed to thirty minutes of Mozart’s music in one session, once per day expend less energy—and therefore need fewer calories to grow rapidly—than when they are not “listening” to the music

In the study, Dr. Mandel and Dr. Lubetzky and their team measured the physiological effects of music by Mozart played to pre-term newborns for 30 minutes. After the music was played, the researchers measured infants’ energy expenditure again, and compared it to the amount of energy expended when the baby was at rest. After “hearing” the music, the infant expended less energy, a process that can lead to faster weight gain.

Not allowing plants to feel is one thing. And I can even understand the discomfort with writing that newborns are listening to music, because that may imply they are attending to it, which is questionable. But why can’t human babies be said to hear music? This is the strangest case of perceptual chauvinism I have yet come across.

Automusic /2009/08/13/automusic/ /2009/08/13/automusic/#comments Thu, 13 Aug 2009 16:28:21 +0000 David Birnbaum http://tactilicio.us/?p=551 How goddamn incredible would it be to have music composed for you on the fly, reflecting your emotions?

Everyone’s ears have suffered the effects of repetitively-played canned music, be it in workplaces, hospital environments or during phone calls made to directory inquiries numbers. On this basis, the research team decided that it would be “very interesting to design and build an intelligent system able to generate music automatically, ensuring the correct degree of emotiveness (in order to manage the environment created) and originality (guaranteeing that the tunes composed are not repeated, and are original and endless).”

And on a related, melodious note, I recently discovered that people have been using auto-tuning software on everyday sounds and speech. Cool! Here’s an auto-tuned baby crying.

If babies could be made to always sound like this when they cry, would the birth rate go up? Would people be less motivated to help infants in trouble because the crying would be less irritating? Would the kid develop musical abilities unlike any in history?
