* CD lab files done. Refining the script.
* Training toolkit is cleaned up. Now no alignment is required. Parallel training is done.
* Tried syllable based system instead of phones.
* Collected an online-novel reading.

Next week:

* Refine the script
* Clean up the online reading.

* The search system migrated to the custom domain, with significant performance reduction

* Two problems:
# short of semantic cluster.
# limited training data for idf.

* Next week
# Analyse the QA database, to extract useful domain dependent data
# Analyse the data to expand the key words & phrases
# Analyse the data to attain better IDF.

-* CD lab files done. Refining the script.
+* full-lab training is ready. Trained the first full-lab system with 16k/pseduo 48k data.
-* Training toolkit is cleaned up. Now no alignment is required. Parallel training is done.
+* re-recording 48k data using F00 (500 sentences) and retrain the model. The quality of the signal sounds better, while the quality of pitch is a bit strange. Need more investigation on parameter settings.
-* Tried syllable based system instead of phones.
-* Collected an online-novel reading.
 Next week:
-* Refine the script
+* Check the signal parameters and solve the problem of pitch.
-* Clean up the online reading.
+* Prepare the large data training with both all-F 863 data.
