Better than Prime Time TV

I just discovered a pretty interesting video site that describes itself as a Brilliant Ideas Network for Discourse and Debate: It’s videos include conference speeches and interviews, such as several from the Aspen Idea Festival. Unfortunately, most of the ones that I saw were abbreviated versions of the full speech/interview—tantalizing tidbits instead of complete content.

The video/audio content on the site is organized by category and varies from Entrepreneurship to Science to Visual Arts & Film to (of course) Innovation.

The videos aren’t as mind-changing as as the incredible TED talks, but are definitely worth spending time with.

As a sample, check out this discussion on innovation and R&D breakthroughs:


Disruptive Innovation in Health Care

Most people interested in innovation will have some familiarity with Harvard B-School professor Clayton Christensen and his classic books The Innovator’s Dilemma and The Innovator’s Solution. Christensen recently lectured at MIT on the topic of his upcoming book, The Innovator’s Prescription: A Disruptive Solution to Health Care. Christensen is an excellent lecturer and I recommend that you watch this video, courteously pointed to by Irving Wladawsky-Berger who also provides an excellent summary of the class. Make sure that you allot time for watching—the video is 88 minutes long.

Christensen spends the first half of the lecture reviewing the basic concepts of his first book: the process of disruptive innovation.

Here’s a tip for those who don’t want to watch the video or read his books: if you find yourself in a business that is happily conceding low-margin commodity business to small start-ups and happily retreating to the more lucrative high-margin business, be careful or you may end up as one of Christensen’s case-studies on extinction by disruptive innovation (you will never forget this lesson if you watch Christensen’s video).

I love the way that Christensen phrases his preventive medicine for avoiding extinction by disruptive innovation: create a division that is given an unfettered charter to kill the parent—imagine that mission statement on a conference room wall!

Christensen’s prediction for the future of health care (which begins around the 38–minute mark of the video) is that it will experience disruption due to three emerging technologies:

  • molecular diagnostics,
  • imaging technology,
  • high-bandwidth telecommunication.

Part of his message is something that I heard biotech guru Steve Burrill talk about a couple of years ago when predicting future trends in biotech: that better diagnostics will allow health care professionals to treat causes rather than symptoms. I’ve talked about how my field of hearing impairment will go through a similar transition, with better diagnostics allowing us to identify the physiology behind different hearing loss etiologies and provide individualized treatments. This falls under the general theme of individualization in health care, a future trend not only in my field by in health care in general.

For the rest of Christensen’s thinking on innovation opportunities in health care, check out the video—it’s worth the time.

New Yorker on Speech Recognition

I always hold my breath and get a sinking feeling in my stomach whenever a field in which I have expertise takes center stage in a news story or pop-culture piece. More often than not, there are misrepresentations of both sophisticated and not-so-sophisticated aspects of the field (e.g., see Wired Magazine).

Such errors are a common occurrence in movies and television—accuracy in details play a secondary role to the story, and the vast majority of the audience has no idea whether the details are accurate or not. Pilots may object that the location of landing gear switches are not accurately portrayed in a movie, but does anyone else really care? (I recall the howls of protest that arose as outraged chess players complained about inaccuracies in the portrayal of competitive chess in the charming and under-rated movie Searching for Bobby Fischer—seriously, does anyone really care that the players weren’t writing down their moves, or that the games were actioned-up? Chess players worldwide should have been grateful that such a beautiful portrayal of the game was the framework for such a great family film).

HALThus, it was with surprise that I read a recently published article in the New Yorker on speech recognition by John Seabrook that provided an interesting and accurate tour of speech recognition, with brief asides on on a variety of related fields—the physiology of speech production, the physiology of hearing, prosody of speech—all tied together by the promise of computer-based communication that HAL presented in 2001 when the article’s author was  a little kid. I was also surprised to see a popular magazine reference John Pierce’s Acoustical Society letter Whither Speech Recognition, a scathing throwdown on the field of speech recognition in 1969 by the then executive director of research at Bell Laboratories (in this highly debated letter, Pierce criticized the state of speech recognition research at the time for having a “scarcity in the field of people who behave like scientists and of results that look like science.”) I highly recommend reading this New Yorker article for anyone with an interested in the topic.

One odd aspect of the story is that it ends with a discussion of a company called Sound Intelligence, which has developed audio sensor technology that detects violent activity on city streets for use by police. The company is cited as an example of the successful application of the work that Seabrook detailed on detecting emotion in speech. An engineer of the company, whom I heard speak about their technology last year, is quoted as saying that the Sound Intelligence grew out of auditory modeling research at the University of Groningen and its application to separating speech from background noise. It’s unclear to me how much the success of the technology requires complex auditory models or any of the science and technology the article had detailed up to that point. While I applaud Sound Intelligence’s success, the inclusion of their technology as the coda to an otherwise great review of the speech recognition field makes for an empty conclusion. I’m sure that the folks at Sound Intelligence, however, would disagree with me completely.
