.... methods have been explored in the information retrieval community, which can be classified into the following two fundamental categories: spoken document retrieval, in which written queries are used to search speech (e.g. broadcast news audio) archives for relevant speech information [5, 6, 15 17, 19, 20], speech driven (spoken query) retrieval, in which spoken queries are used to retrieve relevant textual information [2, 3] Initiated partially by the TREC 6 spoken document retrieval (SDR) track [4] various methods have been proposed for spoken document retrieval. However, a relatively ....

.... of the TREC spoken document retrieval conferences [3] as well as the recent DARPA Broadcast News workshops, a number of research groups have been developing multi media browsing tools for text, audio, and video data, which should facilitate the access to news data, combining different modalities [26, 30, 28]. Other applications are considered by [7] who describe an approach to summarize closed captions to about 60 70 of the original text length in Japanese broadcast news, and by [10] who use summarization techniques to convert voicemail messages, transcribed by a speech recognizer, to the Short ....

....video sequences, but rather than a text based search, SNR defines audio based queries that serve as filters for future broadcasts, instead of search criteria for past articles in a database. 1.1. 5 AT T SCAN Researchers at AT T labs recently developed SCAN, the Speech Content Based Audio Navigator [5]. This system supports searching and browsing of a large database of news audio. The SCAN search component (global navigation) uses acoustic information to create short speech documents, and then uses ASR to obtain an errorful transcript of each document. Document transcripts are matched to ....

....is a dangerous mission water s going to be bad that terrain is mountainous Figure 4.1: Example transcription of audio news by IBM ViaVoice. A study of ASR performance on broadcast news showed wide variations, from a maximum of 88 words correctly recognized to a minimum of 35 , with a mean of 67 [5]. ViaVoice does not offer much additional information. It does not return any measure of confidence, nor does it give any indication if it fails to recognize anything from certain portions of audio. New proper nouns in the news, especially names, sometimes contribute significant error because they ....

....as our reference application for several reasons. Voicemail is a pervasive but little studied workplace communication technology, with an estimated 68 million users worldwide [16] Many organizations rely heavily on voicemail for conducting everyday work, and voicemail is often preferred to email [12,18]. Voicemail is also a common feature of most new cellular phones. Yet despite its ubiquity and importance, there are still many problems with current voicemail user interfaces. The structure of the paper is the following. We summarize three previous studies of voicemail usage [16,18,19] which ....

....to email [12,18] Voicemail is also a common feature of most new cellular phones. Yet despite its ubiquity and importance, there are still many problems with current voicemail user interfaces. The structure of the paper is the following. We summarize three previous studies of voicemail usage [16,18,19], which served to motivate our design. Those studies identified four key user problems: message scanning, information extraction, status tracking and archiving. We also identified a central user strategy for voicemail processing, message transcription, in which users transcribe all or part of a ....
