ASR Kernel development

[ASR group weekly report]

TTS

• 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.

Dialog system

• Conducting the initial experiment:

1. Using 9k dim TF/IDF, compose feature vectors for each query, each answer. Mach the TF/IDF of query+answer to match the TF/IDF of new queries.

1. Keep two top-level categories, try to reduce top-level errors:

Add the scores of the Cosine score of the match with queries and answers directly:
top-level errors: 2/60 , all errors: 13/60
Use scores of the Cosine score of the match with queries only:
top-level errors: 0/60 , all errors: 7/60
speed: 2 query/second

Next week:

• Reverse index-based fast match (only match with queries)

1. code done in python
2. CER 7/60, speed 1 query/second

• Use the new data set to verify the program.
