A STUDY ON MANDARIN BROADCAST NEWS SPEECH RECOGNITION

by C. L. Chen, Y. R. Wang, S. H. Chen
"... In this paper, a basic Mandarin broadcast news speech recognition system is constructed using the MATBN database. It considers the acoustic modeling for Mandarin base-syllables, particles, and paralinguistic phenomena. It also considers environment-dependent acoustic modeling for three recording env ..."

The CU-HTK Mandarin broadcast news transcription system

by R. Sinha, M. J. F. Gales, D. Y. Kim, X. A. Liu, K. C. Sim, P. C. Woodland - IN ICASSP, 2006. IV 1280 , 2006
"... This paper discusses the development of the CU-HTK Mandarin Broadcast News (BN) transcription system. The Mandarin BN task includes a significant amount of English data. Hence techniques have been investigated to allow the same system to handle both Mandarin and English by augmenting the Mandarin tr ..."

Retrieval of Mandarin Broadcast News Using Spoken Queries

by Berlin Chen, Hsin-min Wang, Lin-shan Lee - In Proc. International Conference on Spoken Language Processing, (ICSLP2000 , 2000
"... Considering the monosyllabic structure of the Chinese language, a whole class of indexing features for retrieval of Mandarin broadcast news using syllable-level statistical characteristics has been previously investigated. This paper presents the improvements achieved over the previous results. The ..."

Lightly Supervised and Data-Driven Approaches to Mandarin Broadcast News Transcription

by Berlin Chen, Jen-wei Kuo, Wen-hung Tsai - Proc. IEEE International Conference on Acoustics, Speech, Signal processing
"... This article investigates the use of several lightly supervised and data-driven approaches to Mandarin broadcast news transcription. With the special structural properties of the Chinese language taken into consideration, a fast acoustic look-ahead technique for estimating the unexplored part of a s ..."

Unsupervised training for Mandarin broadcast news and conversation transcription

by L. Wang, M. J. F. Gales, P. C. Woodland - IN PROC. ICASSP , 2007
"... A significant cost in obtaining acoustic training data is the generation of accurate transcriptions. For some sources close-caption data is available. This allows the use of lightly-supervised training techniques. However, for some sources and languages close-caption is not available. In these cases ..."

. Two forms of selection are described, one to remove non-target language shows, the other to remove segments with low confidence. Experiments were carried out on a Mandarin transcriptions task. Two types of test data were considered, Broadcast News (BN) and Broadcast Conversations (BC). Results show

Prosody-based Topic Segmentation for Mandarin Broadcast News

by Gina-Anne Levow
"... Automatic topic segmentation, separation of a discourse stream into its constituent stories or topics, is a necessary preprocessing step for applications such as information retrieval, anaphora resolution, and summarization. While significant progress has been made in this area for text sources and ..."

and for English audio sources, little work has been done in automatic, acoustic feature-based segmentation of other languages. In this paper, we focus on prosody-based topic segmentation of Mandarin Chinese. As a tone language, Mandarin presents special challenges for applicability of intonation-based techniques

The Isl Rt04 Mandarin Broadcast News Evaluation System

by Hua Yu, Yik-cheung Tam, Thomas Schaaf, Sebastian Stüker, Qin Jin, Mohamed Noamany, Tanja Scultz - IN EARS RICH TRANSCRIPTION WORKSHOP, PALISADES , 2004
"... This paper describes our effort in developing a Mandarin Broadcast News system for the RT-04f (Rich Transcription) evaluation. Starting from a legacy system, we revisited all the issues including partitioning, acoustic modeling, language modeling, decoding and system combination strategies. We have ..."

Speech summarization without lexical features for Mandarin broadcast news

by Jian Zhang, Pascale Fung - ASSOCIATION FOR COMPUTATIONAL LINGUISTICS , 2007
"... We present the first known empirical study on speech summarization without lexical features for Mandarin broadcast news. We evaluate acoustic, lexical and structural features as predictors of summary sentences. We find that the summarizer yields good performance at the average F-measure of 0.5646 ev ..."
