This paper details our subword confusion network based approach for Mandarin spoken term detection. As well as the system description, two approaches are presented for improvement of our baseline system. To reduce the inherent high recognition error of the subword decoding system due to its weak language model constraints, the subword confusion network is proposed to be generated from the word decoding...
The SMS receiving and dispatching system is designed in this paper, which consisting of embedded Linux system and GPRS module. The principle of work and frame of system are given. How to encode the message in PDU mode, decode the message from PDU and the SMS receive/send flow under the control of AT commands, is the technical difficulty in SMS terminal developing. based on the embedded Linux system,...
The speech recognition accuracy has been observed to decrease for nonnative speakers, especially those who are just beginning to learn foreign language or who have heavy accents. This paper presents a novel bilingual model modification approach to improve nonnative speech recognition via considering these great variations of accented pronunciations. Each state of the baseline nonnative acoustic models...
This paper presents our recent work on the development of a grammar-constrained, Mandarin-English bilingual speech recognition system (MESRS) for real world music retrieval. In order to balance the performance and the complexity of the bilingual SR system, an unified single set of bilingual acoustic models derived by phone clustering is developed. A novel two-pass phone clustering method based on...
