“…In addition to the well-established research line in linguistics, implications of CS and other kinds of language switches for speechto-text systems have recently received some research interest, resulting in some robust acoustic modeling [1][2][3][4][5] and language modeling [6][7][8] approaches for CS speech. Language identification (LID) is a relevant task for the automatic speech recognition (ASR) of CS speech [9][10][11][12].…”

“…That is, when aligning recognition results with the reference transcriptions, insertions, deletions, substitutions were evaluated respectively for each language and summed up for overall evaluation. The basic unit for alignment is character for Mandarin and word for English [3] [12], so the accuracies reported here are with respect to characters for Mandarin and to words for English.…”

“…We used the KneserNey tri-gram model, started with a background model and then adapted with the transcription of the training set for the target lecture here. The way the recognition accuracy was evaluated followed the earlier works [3], [12]. That is, when aligning recognition results with the reference transcriptions, insertions, deletions, substitutions were evaluated respectively for each language and summed up for overall evaluation.…”

“…They discover that clustering all foreign words into their POS classes leads to the best performance. In (Li et al, 2012;Li et al, 2013), the authors propose to integrate the equivalence constraint into language modeling for Mandarin and English CodeSwitching speech recorded in Hong Kong.…”
