David Huggins-Daines (PocketSphinx developer) has an article in his wiki comparing Sphinx 3.0 and HTK speech recognition engines.  From the article:

The short story is that, after controlling for the beam widths, language model weights, number of tied states and Gaussians, and the acoustic features, Sphinx 3.0 is actually a bit more accurate than [HTK's] HVite. This is not a very meaningful test, because both are extremely slow (over 5xRT [Real Time] on a 2.8GHz Pentium4). However, it does show that there is nothing inherently wrong with the Sphinx trainer, at least on a basic maximum-likelihood training task.

The Julius speech recognition engine uses HTK acoustic models.

Hi,

Does anyone tested julius and sphinx voice recognition engines, in order to compare them (and tell me if you are agree with David Huggins-Daines or not, in the accuarate of both programs).

Thanks in advance.

Hi Ubanov,

This page on the Simon project website is interesting, it's really the only comparison that I have found between Julius and Sphinx:

Analysis of existing software (translated from German using Google translate - original page)

They chose Julius over Sphinx and some other commercial products (based on criteria for their specific application context).
