  1. Speed-up Facilities in s3.3 GMM Computation Seach Lexicon Structure Tree. Pruning Standard Heuristic Search Speed-up Not Implemented Frame-Level Not implemented Senone-Level Not implemented Gaussian-Level SVQ-based GMM Selection Sub-vector constrained to 3 Component-Level SVQ code removed

  2. Summary ofSpeed-up Facilities in s3.4 GMM Computation Seach Lexicon Structure Tree Pruning (New) Improved Word-end Pruning Heuristic Search Speed-up (New) Phoneme-Look-ahead Frame-Level (New) Naïve Down-Sampling (New) Conditional Down-Sampling Senone-Level (New) CI-based GMM Selection Gaussian-Level (New) VQ-based GMM Selection (New) Unconstrained no. of sub-vectors in SVQ-based GMM Selection Component-Level (New) SVQ code enabled

  3. Near Term Improvement of Decoder • Improve LM facilities (Avail at Mar 31) • Improve speed-up techniques (Avail at Mar 31) • Complete phoneme look-ahead research • Complete machine optimization in Intel platform • Enable speed-up in live-mode recognition. (Avail at Mar 31) • Improved search structure • Modify code to use lexical tree copies (Apr 15) • Modify code to handle cross-word triphones (Apr 30)

  4. Training Plan • Text-Processing (Avail at Mar 31) • First Pass of Acoustic/Language Modeling (Avail at Apr 15) • With the help of the new 4 cpus machine. • Training using standard recipe • CD + CI mode first pass models. • Trigram models. • Second Pass of Acoustic/Language Modeling • Improved training. • Decide what we should do after we get the results. • AM/LM Adaptation?
