....numbers Fix field trial refs There are increasing amounts of on line public, corporate, and private speech data, including broadcast news, corporate announcements, meeting records and voicemail archives. Such speech data has general benefits over text, being both expressive and easy to produce [1,4,7,12,20]. Currently, however, its use is hampered by the lack of effective end user tools for accessing and manipulating it. Speech is a serial medium that does not readily support search, visual scanning or key word spotting. We can contrast this with tools for accessing text. Text has the benefit of ....

....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 ....

A major problem is the accurate reporting of meeting results when the scribe is not well versed in all the topics [15]. A survey of 142 PDA users [12] found that note taking was the most popular application of Apple Newton users (of six applications) but was far less popular with Pilot users (ranked fourth of six) Note taking was also cited as the most common task (of seven) that users performed on paper ....

Xerox PARC has a long tradition of exploring the value of collaborative tools for meeting capture [20,18] and salvage [15]. Unlike the Arizona tools, these tools support unstructured, sketch based interfaces. Although NotePals is fairly limited compared to many of these systems, it was influenced by there informal interfaces. Again, NotePals attacks the fundamental problems of these systems: cost and ubiquity. ....

The timestamp for each note could be used to link it to a specific event in an audio record or the slide that was being presented at the moment the note was taken [6].

It uses simple, inexpensive equipment that can be obtained by many workgroups and supports any style of meeting in any setting. NotePals informal, ....

A CIA can be thought of as using the same infrastructure as these systems or built on top of these kinds of systems. ....

....touchtone or speech based. However, the Web and PDAs will soon make graphical UI methods more widely available for accessing voicemail. Graphical access may have significant advantages: visual indices have been used successfully as a general technique to access other types of speech archives [1,2,5,6,7,9,11,12,15,17]. Visual representation of speech structure allows random access to an inherently serial medium. The aim of this paper is to explore how these new visual indexing techniques can be applied to voicemail access, in particular to address documented problems with current touchtone UIs [13] We also ....

....users reported the need for repeated replayings of the message to extract critical information. We therefore wanted to provide ways to rapidly identify and replay only the most relevant parts of the message, without having to listen to the entire message. User notes are therefore also time indexed [9,12,15]. The motivation for this came from the observation that handwritten notes serve as an index into the underlying structure of the original voicemail message: my notes trigger things they are . meant to just give me place holders while I am browsing. Then I have to go back and listen to ....

Tools are now being developed to assist in capturing important moments in meetings, and managing that corpus of material [Moran 1997]. As the intended user base of a group memory system expands from the core team, to encompass wider circles of staff, the common ground which can be assumed decreases, thus increasing the amount of implicit knowledge that needs to be made explicit. One way to think about this process is as the ....

A number of other researchers have explored the role of audio in distributed collaborative work and media space settings. Researchers at PARC [Mor97] and MIT [Kob97] explored the problem of browsing for audio data. Seligmann et al.

....Media Lab (Stifelman 1992) demonstrates the utility of personal note taking with automatic audio enhancement for later review. Research in ubiquitous meeting capture has mostly focused on promoting collaboration through shared work surfaces. The Dolphin (Streitz 1994) and Tivoli (Minneman 1995; Moran 1997) systems provide shared surfaces with various tools for drawing and manipulating content that can later be reviewed with audio enhancement. Ubiquitous capture of design knowledge has several benefits over traditional rationale capture techniques. First, it is cheap in terms of the effort of ....

....Digitized media clips can be played and views of organized subsets of the analysis data can be displayed. All of the interactions between the Insight Lab s objects, devices, equipment, and displays are managed by Insight MAST. The best way to quickly and easily view data is to digitize it [3] [13]. Providing easy, non linear access to the original source data is essential. For example, during analysis a team views media clips to create consensus about the meaning of pieces of evidence and to clarify their interpretations of events that transpire in a particular media segment.

An interesting feature is that the beamed notes contain the times they were created (which is used later to control playback of the recorded audio [13]) and the note objects have a property for these times, shown as the little clocks in Figure 6.
