Two techniques to improve the detection of out-of-vocabularykeywords are assessed in this study: using extra text resources to augment the lexicon andlanguage model, and via subword units for keyword search. Two approaches for dataaugmentation are explored to extend the limited amount of transcribed conversationalspeech: using conversational-like Web data and texts generated by recurrent neuralnetworks. Contrastive comparisons of subword-based systems are performed to evaluatethe benefits of multiple subword decodings and single decoding. Keyword search results arereported for all the techniques, but only some improve performance. Results are reported forthe Mongolian and Igbo languages using data from the 2016 Babel program.
