This paper presents an improved framework for voice retrieval of Mandarin broadcast news speech. First, several unsupervised and data-driven approaches for broadcast news transcription were proposed to improve the speech recognition accuracy and efficiency. Then, a multiscale indexing paradigm

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

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

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

This paper presents a system for speech retrieval of Mandarin broadcast news. First, several data-driven and unsupervised approaches are integrated into the broadcast news transcription system to improve the speech recognition accuracy and efficiency. Then, a multi-scale indexing paradigm

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

. 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

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

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

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
