Summary: Spoken language is a major area of linguistic research and speech technology development. This handbook presents an introduction to the technical foundations and shows how speech data is collected, annotated, analysed, and made accessible in the form of speech databases. The book focuses on web-based procedures for the recording and processing of high quality speech data, and it is intended as a desktop reference for practical recording and annotation work. A chapter is devoted to the Ph@ttSessionz database, the first large-scale speech data collection (860+ speakers, 40 locations in Germany) performed via the Internet. The companion web site (http://www.narr-studienbuecher.de/Draxler/index.html) contains audio examples, software tools, solutions to the exercises, important links, and checklists.

I received this very good news from Joseph P. Campbell (MIT Lincoln
Laboratory):

The entire Bell System Technical Journal from 1922--1983 is now
available on line! It is offered in PDF format sorted by year, volume, and
issue; and it is searchable:

http://bstj.bell-labs.com/

BSTJ holds a wealth of consolidated information of outstanding contributions
from Bell Labs over the years. For example, check out Fletcher's 1922
article 'The Nature of Speech and Its Interpretation', BSTJ, vol 1, no 1.
Also see Shannon's landmark paper and much, much more!

As Joe pointed out, the current generation of researchers didn't grow up
with BSTJs under their bed like we both did, but for the older generation
that remembers these great articles, this is indeed very good news.

New Publications

(1) ACE Time Normalization (TERN) 2004 English Evaluation Data V1.0 was developed by researchers at The MITRE Corporation. It contains the English evaluation data prepared for the 2004 Time Expression Recognition and Normalization (TERN) Evaluation, sponsored by the Automatic Content Extraction (ACE) program, specifically, English broadcast news and newswire data collected by LDC. The training data for this evaluation can be found in ACE Time Normalization (TERN) 2004 English Training Data v 1.0 LDC2005T07.

The purpose of the TERN evaluation is to advance the state of the art in the automatic recognition and normalization of natural language temporal expressions. In most language contexts such expressions are indexical. For example, with 'Monday,' 'last week,' or 'three months starting October 1,' one must know the narrative reference time in order to pinpoint the time interval being conveyed by the expression. In addition, for data exchange purposes, it is essential that the identified interval be rendered according to an established standard, i.e., normalized. Accurate identification and normalization of temporal expressions are in turn essential for the temporal reasoning being demanded by advanced NLP applications such as question answering, information extraction and summarization.

The data in this release is English broadcast transcripts and newswire material from TDT4 Multilingual Text and Annotations LDC2005T16. The annotation specifications for this corpus were developed under DARPA's Translingual Information Detection Extraction and Summarization (TIDES) program, with support from ACE. All files have been doubly-annotated by two separate annotators and then reconciled, using the TIDES 2003 Standard for the Annotation of Temporal Expressions.  The data directory contains the corpus which consists of 192 files (54K words).

(2) Korean Newswire Second Edition is an archive of Korean newswire text that has been acquired over several years (1994-2009) at LDC from the Korean Press Agency. This release includes all of the content of Korean Newswire (LDC2000T45) (June 1994-March 2000) as well as newly-collected data.  The second edition contains all data collected by LDC from April 2000 through December 2009.

All material, including that from the first release, has been converted to UTF-8 (except for more recent data already in UTF-8 format) and processed in LDC's gigaword format. The gigaword format classifies newswire content into three types: story, multi and other where 'story' refers to an article containing information pertaining to a particular event on a day; 'multi' refers to an article that contains more than one story relating to different topics; and 'other' refers to articles containing lists, tables or numerical data, such as sports scores.

A word break error in the original release and in data collected from January 2002 through February 2005 has been corrected in the second edition with the result that all Korean text should display correctly. The error involved a line break in the middle of a word with the result that an affected word appeared in segments in two lines. This problem was  resolved using word histograms and a few

(3) NIST 2006 Open Machine Translation (OpenMT) Evaluation is a package containing source data, reference translations and scoring software used in the NIST 2006 OpenMT evaluation. It is designed to help evaluate the effectiveness of machine translation systems. The package was compiled and scoring software was developed by researchers at NIST, making use of broadcast, newswire and web newsgroup source data and reference translations collected and developed by LDC.

The objective of the NIST Open Machine Translation (OpenMT) evaluation series is to support research in, and help advance the state of the art of, machine translation (MT) technologies -- technologies that translate text between human languages. Input may include all forms of text. The goal is for the output to be an adequate and fluent translation of the original.  The OpenMT evaluations are intended to be of interest to all researchers working on the general problem of automatic translation between human languages. To this end, they are designed to be simple, to focus on core technology issues and to be fully supported. The 2006 task was to evaluate translation from Arabic to English and from Chinese to English.  Additional information about these evaluations may be found at the NIST Open Machine Translation (OpenMT) Evaluation web site.

This evaluation kit includes a single Perl script (mteval-v11b.pl) that may be used to produce a translation quality score for one (or more) MT systems. The script works by comparing the system output translation with a set of (expert) reference translations of the same source text. Comparison is based on finding sequences of words in the reference translations that match word sequences in the system output translation.

The included scoring script was released with the original evaluation, intended for use with SGML-formatted data files, and is provided to ensure compatibility of user scoring results with results from the original evaluation. An updated scoring software package (mteval-v13a-20091001.tar.gz), with XML support, additional options and bug fixes, documentation, and example translations, may be downloaded from the NIST Multimodal Information Group Tools website.

This release contains of 357 documents with corresponding sets of four separate human expert reference translations. The source data is comprised of Arabic and Chinese newswire documents, human transcriptions of broadcast news and broadcast conversation programs and web newsgroup documents collected by LDC in 2006. The newswire and broadcast material are from Agence France-Presse (Arabic, Chinese), Xinhua News Agency (Arabic, Chinese), Lebanese Broadcasting Corp. (Arabic), Dubai TV (Arabic), China Central TV (Chinese) and New Tang Dynasty Television (Chinese). The web text was collected from Google and Yahoo newsgroups.

For each language, the test set consists of two files: a source and a reference file. Each reference file contains four independent translations of the data set. The evaluation year, source language, test set, version of the data, and source vs. reference file are reflected in the file name.
