CU Move: In-Vehicle Speech Research and Corpus Development ...

 

CSLR has been involved in In-Vehicle speech research for voice navigation and route planning. We have completed the CU-Move corpus collection which includes 500 speakers from 6 U.S. from across the United States. The speech data consists of speech in 5 phases (route navigation requests, phone and credit card numbers, route destinations and street addresses, phonetically balanced sentences, Wizard of Oz route navigation between field subjects and WOZ operators here at CSLR). The entire corpus in it's original format consists of over 600GB of data. We have completed the distribution of this data in 3 hard-disk releases (includes data preparation - downsampling & microphone beamforming, as well as transcription of all recordings). If you are interested in obtaining this diverse and valuable in-vehicle corpus, see CSLR License Agreement page. For more information on the CU-Move project, see CU-Move web page.
