Kosp2e: Korean Speech to English Translation Corpus
Most speech-to-text (S2T) translation studies use English speech as a source,
which makes it difficult for non-English speakers to take advantage of the S2T
technologies. For some languages, this problem was tackled through corpus
construction, but the farther linguistically from English or the more
under-resourced, this deficiency and underrepresentedness becomes more
significant. In this paper, we introduce kosp2e (read as `kospi'), a corpus
that allows Korean speech to be translated into English text in an end-to-end
manner. We adopt open license speech recognition corpus, translation corpus,
and spoken language corpora to make our dataset freely available to the public,
and check the performance through the pipeline and training-based approaches.
Using pipeline and various end-to-end schemes, we obtain the highest BLEU of
21.3 and 18.0 for each based on the English hypothesis, validating the
feasibility of our data. We plan to supplement annotations for other target
languages through community contributions in the future.Comment: Interspeech 2021 Camera-read
Application of a non-hazardous vital dye for cell counting with automated cell counters
AbstractRecent advances in automated cell counters enable us to count cells more easily with consistency. However, the wide use of the traditional vital dye trypan blue (TB) raises environmental and health concerns due to its potential teratogenic effects. To avoid this chemical hazard, it is of importance to introduce an alternative non-hazardous vital dye that is compatible with automated cell counters. Erythrosin B (EB) is a vital dye that is impermeable to biological membranes and is used as a food additive. Similarly to TB, EB stains only nonviable cells with disintegrated membranes. However, EB is less popular than TB and is seldom used with automated cell counters. We found that cell counting accuracy with EB was comparable to that with TB. EB was found to be an effective dye for accurate counting of cells with different viabilities across three different automated cell counters. In contrast to TB, EB was less toxic to cultured HL-60 cells during the cell counting process. These results indicate that replacing TB with EB for use with automated cell counters will significantly reduce the hazardous risk while producing comparable results
