Open Source Speech Recognition - With Source

Paul Lamere writes " This story on ZD-Net and this recent story on Slashdot describes the recent open sourcing of IBM's voice recognition software. This release, unfortunately, doesn't include any source for the actual speech recognition engine. Olaf Schmidt, a developer on the KDE Accessibility Project , is quoted as saying 'There is no speech-recognition system available for Linux, which is a big gap.' In an attempt to close this gap, we have just released Sphinx-4, a state-of-the-art, speaker-independent, continuous speech recognition system written entirely in the Java programming language. It was created by researchers and engineers from Sun, CMU, MERL, HP, MIT and UCSC. Despite (or because of) being written in the Java programming language, Sphinx-4 performs as well as similar systems written in C. Here are the release notes and some performance data."

Interesting side note

[2forshow]

Kind of interesting side note I have a professor who worked for IBM about 30+ years ago where he designed circuits to filter out frequencies above the third or fourth harmonic. It is somewhat difficult because the voice has no repeating patterns (like a complex sinusoidal wave) within a given word. So the engineers had to decide when it is appropriate to filter out the higher frequencies and still have the voice sounce clear. The found that anything above the fifth harmonic didn't make a big difference so for most cases they used the third or fourth harmonic. Do you want a free Sony 27" flatscreen TV or maybe a 17" flatscreen monitor? From those who brought you free Ipods comes Free Flatscreens. http://www.FreeFlatScreens.com/default.aspx?refere r=9534369

And, as usual, they give no actual NUMBERS to support this claim.

I call bullshit.

Yes, in small, isolated benchmarks, occasionally Java can compare to C. But in large applications, it's dreadfully slow.
