Theory and practice of acoustic confusability
In this paper we define two alternatives to the familiar perplexity statistic (hereafter lexical perplexity), which is widely applied both as a measure-of-goodness and as an objective function for training language models. These alternatives, respectively acoustic perplexity and the synthetic acoustic word error rate, fuse information from both the language model and the acoustic model. We show...
متن کاملPredicting word correct rate from acoustic and linguistic confusability
When adapting an existing ASR-application for different user environments, one often gets confronted with speech that does not entirely match the training situation. Differences may stem both from acoustic and linguistic causes. In this paper we explore to what extent the word correct rate (wcr) for a given test set can be predicted from the transcription only (i.e. the linguistic representatio...
متن کاملLexicon Optimization for WFST-Based Speech Recognition Using Acoustic Distance Based Confusability Measure and G2P Conversion
In this paper, we propose a lexicon optimization method based on a confusability measure (CM) to develop a large vocabulary continuous speech recognition (LVCSR) system with unseen words. When a lexicon is built or expanded for unseen words by using grapheme-to-phoneme (G2P) conversion, the lexicon size increases since G2P is generally realized by 1-to-N-best mapping. Thus, the proposed method ...

متن کاملConfusability of Chinese Intonation
Do lexical tones interfere with the realization of intonation types? Given that tone and intonation both use F0 as a primary cue, can a listener reliably identify statements and questions when some of the channel capacity is taken up by lexical tones? We study this issue through a perception test on a carefully designed and obtained intonation corpus on Mandarin Chinese. Our study shows the fol...
