Statistical Speech Technology Group Software

Our policy: everything we write is free on the web. This wiki is intended to be definitive, because anybody in the group can edit it to add their own software. A spider-indexable backup is at http://www.isle.uiuc.edu/software .

Our software is available via subversion, using login name "anon" with no password (hit "enter" when a password is requested).

improved MVAPerform mean and variance normalization and ARMA filtering

It's essentially this version, improved:

  • better error reporting (e.g. failing to open file tells you so instead of core dumping)
  • more accurate mean and variance estimation (doubles instead of floats in strategic places)
  • faster computation in the case of MV (ARMA order 0)

Phonetic Transcription Tool

This tool computes American English phonetic transcriptions from plaintext. Its HMM either generates a most likely phonetic transcription, or forces alignment if a phonetic transcription is provided.

So, it gives a reasonable pronunciation for both out-of-dictionary words and partially pronounced words.
