        Actually, use of speech recognition technology to index video clips for search engines _is_ both a very desirable technology, and something that can be done fairly easily (most professionally produced video, at least, takes great pains to have one speaker at a time and keep noise to a minimum). There's a fair bit of video content accessible via the web right now, and this will only increase (most new digital cameras can take video clips now - remember how quickly still pictures flooded the web when digicams first became available?).

        Speech recognition technology has trouble when it's trying to sort out a noisy environment or a degraded communications channel, and has trouble holding useful open-ended conversations (as opposed to task-driven), but it's very capable in most other contexts. After all, the field has been under study for decades.

        In summary, your mocking of the parent post is premature.

    "Computer, make coffee!"
    "Computer, Earl Grey, hot!"

Imagine if their computers could suddenly understand them a thousand times better? They could talk to their computers a bit more naturally, thus saving their vocal chords from undue stress.

    - Voice notes on embedded devices (store only text!)
    - Helpful Kiosks that can give you directions
    - A new use for natural language database queries (i.e. Ask the computer what last quarter's net sales were.)

    From Carnegie Mellon University:

    Carnegie Mellon engineering researchers to create speech recognition in silicon

    Team to develop new silicon chip

    Carnegie Mellon University's Rob A. Rutenbar is leading a national research team to develop a new, efficient silicon chip that may revolutionize the way humans communicate and have a significant impact on America's homeland security.

    Rutenbar, a professor of electrical and computer engineering at Carnegie Mellon, working jointly with researchers at the University of California at Berkeley received a $1 million grant from the National Science Foundation to move automatic speech recognition from software into hardware.

    ''I can ask my cell phone to 'Call Mom,''' says Rutenbar, ''but I can't dictate a detailed email complaint to my travel agent or navigate a complicated Internet database by voice alone.''

    The problem is power--or rather, the lack of it. It takes a very powerful desktop computer to recognize arbitrary speech. ''But we can't put a PentiumTM in my cell phone, or in a soldier's helmet, or under a rock in a desert,'' explains Rutenbar, ''the batteries wouldn't last 10 minutes.''

    Thus, the goal is to create a radically new and efficient silicon chip architecture that only does speech recognition, but does this 100 to 1,000 times more efficiently than a conventional computer.

    The research team is uniquely poised to deliver on this ambitious project. Carnegie Mellon researchers pioneered much of today's successful speech recognition technology. This includes the influential 'Sphinx' project, the basis for many of today's commercial speech recognizers.

    ''We're still not even close to having a voice interface that will let you throw away your keyboard and mouse, but this current research could help us see speech as the primary modality on cell phones and PDAs,'' said Richard Stern, a professor in electrical and computer engineering and the team's senior speech recognition expert. ''To really throw away the keyboard, we have to go to silicon.'' But enhanced conversations between people and consumer products is not the main goal. ''Homeland security applications are the big reason we were chosen for this award,'' says Rutenbar. ''Imagine if an emergency responder could query a critical online database with voice alone, without returning to a vehicle, in a noisy and dangerous environment. The possibilities are endless.''

    Researchers plan to unveil speech-recognition chip architecture in two to three years.

      Natural language processing and speech recognition are two entirely separate problem spaces.

      Natural language processing tasks involve parsing strings of tokens and mapping them to commands to be executed. So, from your example, "Pull up the name of employee number 12345", the natural language system must map "Pull up" to "SELECT", "the name" to "name", "of employee number 12345" to "FROM users where id = 12345". Really, it's largely a problem of context, and your example shows an excellent problem: the "of employee number 12345" to "FROM..." map requires the contextual information of where to pull this information from. Surely multiple tables of a database could have an "employee number" field in them. Do you want all of the tuples which matches, or just from a certain table? Now, in the context of looking up a bunch of other employees, maybe I know what table you've been hitting a lot, and can determine what you're asking, but without that context, I have no idea.

      In fact, everyday speech has a lot more ambiguity in it than could be handled without keeping large amounts of state, be it contextual or experiencial/situational. For example, if I overhear two people in a conversation, and the first thing I hear is: "Yeah, but he's been lying all though his campaign, and I for one don't support him," I have no idea which politcal candidate might be speaking of. However, if I saw that person wearing a shirt for a political campaign last week, then I have enough context to make a reasonable guess that he's talking about that person's opponent.

      Speech recognition is a "lower level" than that: it's about matching acoustic information into speech sounds and then using the speech sounds to determine the word that was said. This is a hugely complex task that has a number of unsolved problems (of which these are the 3 that I can think of off the top of my head):

      1) "speech sounds" are fuzzy categories, and are not canonical targets.
      2) salient "features" of phonemes are disputed, contradictory and large amounts of redundancy/conflicting info are built into the speech signal
      3) idiosyncratic speaker-to-speaker differences make the phoneme categories even fuzzier and can complicate the task even for the one speech recognition system that we know works: the human brain.

      At any rate, the problems that need to be solved for speech recognition are not the same problems in natural language processing. While there may be some cross over in pattern-matching, the specifics of the problem spaces make it unlikely that you will get much benefit for NLS (natural language systems) from just making the algorithms faster.

      Which, in fact, is my main criticism of this article: the algorithms that we have now are piss-poor, and making them faster doesn't intrinsically make them better. Unless there's been some huge advance in the field that I'm unaware of, you'd still have to train a SRS (speech recognition system) on your idiolect, by reading some pre-selected passages to it. This model has lots of problems, most specially that it's tailored to an individual. Imagine if you had to have each person that you spoke with read some canned paragraphs to you the first time you met so that you could interact....

This means that a program trained for a Bostonian may not work for someone from Arkansas, Texas, or Louisiana. Also, the programs' effectiveness decreased over time if you did not use it regularly.

    This seems like a situation where a hardware accelerated approach is pretty sensible. I'm guessing there is large amounts of signal processing involved in speech recognition. With a custom chip like this it probably helps greatly to offload some of that onto a dedicated chip in the same way as GPUs are used on graphics cards. The only problem I can see is that there might not be much market for it. GPUs have an obvious market (games), but there is less demand for speech processing. Star-Trek style interfaces are nice to dream of but for most common tasks a keyboard and mouse will probably give you a faster and more accurate interface.

      Every time a dollar value is placed on a piece of research, some idiot comes along and say "Hey! This could be spent providing clean drinking water, and food and shelter", as if only research that directly provides clean drinking water or food or shelter is worth funding. Quite frequently the idiot making this statement is in a perfect position to provide money to ensure that more people have access to these facilities, and just as frequently that idiot isn't doing so.

      I'm sure that when America and Russia were engaged in the space race there were people saying "Hey! This money could be better spent on disaster relief!". And where are we now? Only a few short decades later we have sattelites that tell us where hurricanes are going so that we can evacuate areas and people who would otherwise die surviveWe have a global reliable telecommunications satellites so that disaster relief agencies in third world countries can inform people of what supplies are required, and people who would otherwse die survive.

      Without the massive investment in jet airline technology that could otherwise have been spent "saving the starving", we would not be able to travel to disaster areas within hours of an incident. And so the list goes on.

      If you personally want to see more money invested in agencies that provide disaster relief, or reliable shelter or clean water then you only have to donate to the right charities, and encourage others to do the same. It doesn't take many people to donate out of their pockets to provide $1 million. You can start here [savethechildren.org].

    Then, the pentium class cpus came about, and a p90 could just do the whole thing without the dsp.

    So, now someone is developing a new dedicated piece of silicon for this.. lets see how long it takes for general purpose computers to catch up.

    The issue is not that this is not usefull, but that it either has to keep developing, or offer a somewhat longer lasting price/performance ratio or much better features for a logn time to come.

    Using specialised DSPs makes more sense to me than burning up generic CPU cycles. There have been many examples over the years of how a specialized DSP is more efficient and effective for a narrow task than a regular CPU. Look at portable MP3 players. They use tiny specialized DSPs to decode the files in a manner that is much more efficient than using a regular CPU.

    We'll still need to do traditional development to interpret the data from the DSPs. We'll need to parse the output so that we can use natural commands to control devices.

    Although $1million significantly can speed things up, this is a pretty ambitious undertaking.

    My Master's research was on implementing machine learning in hardware, specifically support vector machines.

    Now, they have much more money than I did, and probably this will be a collaboration involving many graduate students, but converting complex algorithms from software to hardware is no easy task.

    It is just easier to do things in software, that's why it has evolved. The modular layers of abstraction allow a Computer Scientist working in machine learning or speech recognition to not have to worry about how the underlying hardware works.

    Working in hardware, a lot these issues come face to face. Particularly since you want an architecture on a chip, whereas in a conventional desktop/server system there are resources such as lots of RAM, harddrive space, etc are available and their interconnections have been built and refined over decades.

    Throw in concerns about small form factor, low power consumption, quite fast a lot of unexpected hurles pop up.

    My master's research goal was to produce a data mining/machine learning machine, or at the very least a data mining/machine learning co-processor. In retrospect, that was a very ambitious goal that would require many years of work, probably in collaboration with other graduate students.

    What I ended up doing was just Support Vector Machines in digital hardware. Now granted, there is another aspect to my research that I'm not mentioning here, mainly that I didn't use normal floating point mathematical architectures, but a different innovative logarithmic based mathematical architecture. That in itself was a significant undertaking.

    In any case, this sounds like a great project, I just wonder how much they can do in their (in an academic sense) very small time frame of 2-3 years. Even though a lot of preliminary work has probably already been done just to apply for the grant.

    In any case, it is great to see something like this, something to keep in mind in case I ever go back for a Ph.D.
