OpenKWS15 Evaluation

Developers are expected to build systems according to the published evaluation plan. The significant changes between OpenKWS14 and OpenKWS15 are:
 

  • OpenKWS volunteer teams will be supported in multilingual KWS by the release of Build Packs for Cantonese, Pashto, Tagalog, and Turkish in addition to the Vietnamese and Tamil data. 
     
  • Evaluation condition changes:
    • Introduction of the "Very Limited Language Pack" (VLLP) training condition where the build pack consists of 80 hours of audio with call metadata, no phonetic lexicon, 3 hours of transcription excerpts sampled from many training calls. An LSP, like in prior OpenKWS evaluations, will be provided. 
       
    • Additional web text will be provided with the build pack. 
       
    • The Limited Language Pack training condition will be discontinued. 
       
    • The phonetic lexicons will be released only after the evaluation to support analysis.
    • VLLP is required for volunteers who chose to participate in the OpenKWS evaluation. 
       
  • Build pack changes:
    • A portion of the build pack will be designated as the 'tuning set' for setting weights etc. 
       
  • Evaluation schedule changes:
    • Reduction of KWS system build time from 3 to 2 weeks. 
       
    • Two rounds of testing: 
       
      • 1 week for to process the evaluation pack for VLLP condition. 
         
      • 3 weeks to train and test systems for the Full LP condition and additional contrastive system runs.
