INTERSPEECH 2011 Speaker State Challenge Awards
The INTERSPEECH Speaker State Challenge awards prizes in two Sub-Challenges as follows:
In the Intoxication Sub-Challenge, alcoholisation of speakers has to be determined on the Alcohol Language Corpus as two-class classification task: alcoholised for a blood alcohol concentration (BAC) exceeding 0.5 per mill or non-alcoholised. The Challenge measure is the unweighted average recall of these two classes to better compensate for imbalance between classes. However, in the training and development partition also the actual BAC from 0.28-1.75 per mill is provided.
In the Sleepiness Sub-Challenge, sleepiness of speakers has to be determined on the Sleepy Language Corpus by a suited algorithm and acoustic features. While the annotation provides sleepiness in ten levels on the Karolinska Sleepiness Scale, only two classes have to be recognised accordingly: sleepiness for a level exceeding level seven or non-sleepiness. Again, the full information is provided for the training and development partition and the Challenge measure is unweighted average recall of the two classes.
Both Sub-Challenges allow contributors to find their own features with their own classification algorithm. However, a standard feature set is given per corpus that could be used. The labels of the test set are unknown, and participants had to stick to the definition of training, development, and test sets. They had a limited number of five trials to upload their results on the test set, whose labels were unknown to them. A participation had to be accompanied by a paper presenting the results that successfully passed peer-reviewing. Only contributions with an accepted paper were eligible for the Challenge participation. The organisers preserved the right to re-evaluate the findings, but did not participate themselves in the Challenge. Participants were encouraged to compete in both Sub-Challenges.
A prize money of 200.- GBP is awarded per Sub-Challenge sponsored by the HUMAINE Association.
The awardees will be announced during the closing session of INTERSPEECH 2011.
