High School students use LDC data
The team set out to invent an emotive aid in the form of a bracelet that uses a computational algorithm to extract emotional signatures from speech and display expressed emotions in real-time during a conversation. Potential beneficiaries include children with autism, Asperger’s syndrome, or similar diseases that impair the ability to detect emotion. The algorithm employed machine learning and neural network-based techniques to improve accuracy and efficiency relative to current methods.
LDC thanks the InvenTeam’s teacher, Mark Hannum, and group leader, Suhas Gondi, for contributing to this article.
New publications
(1) GALE Phase
This release includes 21 source-translation document pairs, comprising 146,082 characters of Chinese source text and its English translation. Data is drawn from seven distinct Chinese programs broadcast in 2006 and 2007 from the following sources -- China Central TV, a national and international broadcaster in Mainland China and Phoenix TV, a Hong Kong-based satellite television station. Broadcast conversation programming is generally more interactive than traditional news broadcasts and includes talk shows, interviews, call-in programs and roundtable discussions. The programs in this release focus on current events topics.
The data was transcribed by LDC staff and/or transcription vendors under contract to LDC in accordance with Quick Rich Transcription guidelines developed by LDC. Transcribers indicated sentence boundaries in addition to transcribing the text. Data was manually selected for translation according to several criteria, including linguistic features, transcription features and topic features. The transcribed and segmented files were then reformatted into a human-readable translation format and assigned to translation vendors. Translators followed LDCs Chinese to English translation guidelines. Bilingual LDC staff performed quality control procedures on the completed translations.
GALE Phase 2 Chinese Broadcast Conversation Parallel Text Part 1 is distributed via web download.

(2) Greybeard was developed by LDC and is comprised of approximately 590 hours of English telephone conversation speech collected in October and November 2008 by LDC. The goal was to record new telephone conversations among subjects who had participated in one or more previous LDC telephone collections, from Switchboard-1 (1991) through the Mixer studies (2006).
A total of 172 subjects were enrolled in the Greybeard collection, all of whom had participated in one of the following:
Switchboard-1 (LDC97S62) 1991-1992: 2 subjects
Switchboard-2 (LDC98S75, LDC99S79, LDC2002S06) 1996-1997: 16 subjects
Mixer 1 and 2 2003-2005: 103 subjects
Mixer 3 2006: 51 subjects
Most Greybeard participants completed 12 calls. Some subjects completed up to 24 calls. Calls were made or received via an automatic operator system at LDC which connected two participants and announced a topic for discussion.
This release consists of 4680 calls -- the complete set of calls recorded during the Greybeard collection (1098 calls) as well as all calls from the legacy collections that involved the Greybeard speakers.
The audio from each call was captured digitally by the operator system and stored in a separate file as raw mu-law sample data. As the recordings were uploaded daily from the robot operator to network disk storage, automated processes reformatted the audio into a 2-channel SPHERE-format file for each conversation and queued the recordings for manual audit to verify speaker identification and to check other aspects of the recording. Auditors provided impressionistic judgments on overall audio quality, presence of background noise and cross-channel echo and any other technical difficulty with the call, in addition to confirming the speaker-ID on each channel.
Greybeard is distributed on five DVD-ROM.

(3) Manually Annotated
The MASC project was established to address, to the extent possible, many of the obstacles to the creation of large-scale, robust, multiply-annotated corpora of English covering a wide range of genres of written and spoken language data. The project provides appropriate data and annotations to serve as the base for a community-wide annotation effort, together with an infrastructure that enables the incorporation of contributed annotations into a single, usable format that can then be analyzed as it is or transduced to any of a variety of other formats. Further information about the project is available at the MASC website.
The source texts were drawn from the open portion of the American National
All data in this release was annotated for logical structure (paragraph, headings, etc.), token and sentence boundaries, part of speech and lemma, shallow parse (noun and verb chunks) and named entities (person, organization, location and date). Portions of the corpus were also annotated for FrameNet frames (40k full text), Penn Treebank syntax (82k) and opinion (50k).
Manually Annotated Sub-Corpus Third Release is distributed via web download.
