Unsupervised training of a speech recognizer: recent experiments
TLDR
We train a speech recognizer with only a minimal amount (30 minutes) of transcriptions and a large portion (50 hours) of untranscribed data. Expand

Estimating confidence using word lattices
TLDR
We exploit the use of word lattices as information sources for the measure-of-con dence tagger JANKA and show that a high-accuracy MOC tagger can be built based only on the word lattice. Expand

Confidence measures for spontaneous speech recognition
TLDR
We describe the development of the measure of the confidence tagger JANKA, which is able to provide confidence information for the words at the output of the speech recognizer JANUS-3-SR. Expand
