14 Aug 2000: This parallel collection was larger and thought to be more reliable than the automatically transcribed test collection. ... A strategy proven to work well in SDR [2] is blind relevance feedback (BRF) on the test collection.

8 Mar 2000: This corpus spanned January to May 1997 and thus pre-dated the TREC-7 test data. ... 39.73. 44.15. Table 2: Average Precision on the TREC-7 SDR test collection with mean number of query terms in parenthesis.

8 Mar 2000: Two versions of the HTK system were used in the experiments on TREC-6 SDR test data. ... This system gave a word error rate of 24.1% on the TREC-6 test data and ran in about 50 times real time.

1 Mar 2000: On the 1998 test the system produced an average word error rate of 16.1% running in 9.5xRT. ... In tests the faster cache led to 6-8% faster decoder operation on a Xeon than on the equivalent Pentium II.

5 Oct 2000: An important issue in MMIE training is the ability to generalise to unseen test data. ... Tests were performed on both the eval97sub and the 1998 evaluation set (eval98).

1 Mar 2000: BG corr. %M corr. %Correct. %Loss. train/test. 66.26. 97.04. 97.54. 0.03. ... The test set is split into shows available both in training and test and test only.

12 Oct 2000: While MMIE is very effective at reducing training set error a key issue is generalisation to test data. ... It was found that two iterations of MMIE re-estimation gave the best test-set performance [19].

1 Mar 2000: F5. 2.7%. 2.3%. FX. 7.8%. 6.3%. Table 2: Proportion of test data of different audio type. ... The OOV rate on both these test sets using the filtered transcriptions was about 0.5%.

1 Mar 2000: For development test purposes, data broadcast in July 1996 from six shows was used. ... Since two thirds of the broadcast news training and test data is from male speakers there is a significant gender bias which isn't present in the WSJ models.

30 Mar 2000: Development. Evaluation. Name of Query Set. CU60. TREC-7 Test. Number of Queries. ... TREC-6 TEST DATA. Corr. Sub. Del. Ins. Err. NIST/IBM Baseline. 59.1.

2 Mar 2000: The experiments reported here use the TREC-7 SDR test data. For this evaluation, the audio documents came from American broadcast radio and TV news programs which had been manually divided ... The five systems described in section 4.3 were evaluated on

5 Oct 2000: All experiments were performed on the test sets used in the September 1998 and March 2000 Hub5 evaluations (eval98 and eval00, respectively).. ... It can be seen that for the eval00 test set the unmapped posteriors perform much better than for the eval98

30 Mar 2000: This contains the TREC-8 SDR test collection period (Feb 1st to June 30th 1998). ... For development, the 100 hours of TREC-7 SDR test data was used.

2 Nov 2000: The full HUB-4 1997 evaluation test set was used to assess language model performance. ... Treating this as the baseline result to improve upon, statistical significance was tested by using the Wilcoxon signed-rank test at a 5% significance level..

8 Mar 2000: For speech transcription problems with widely varying speaker, channel and background conditions, such as broadcast news transcription, it is beneficial to include unsupervised test-data adaptation to individual speakers and data ... The inter-node costs
