                    Comp.Speech Frequently Asked Questions

   The Frequently Asked Questions (FAQ) is a regular posting to
   comp.speech which attempts to answer some of the regular questions in
   the comp.speech newsgroup. It covers speech synthesis, speech
   recognition, speech coding and a range of related material. It
   contains lists of speech technology software and hardware, including
   commerical products, public domain and freeware software, plus it
   contains over 500 links to speech technology sites and software.

   The FAQ is not meant to discuss any topic exhaustively. It will
   hopefully provide readers with pointers on where to find useful
   information, especially material available on the Internet.

   If you have not already read the Usenet introductory material posted
   to news.announce.newusers, please do. For help with FTP (file transfer
   protocol) look for a regular posting of anonymous FTP FAQ in
   comp.misc, comp.archives.admin or news.answers.

                          Q1.1: What is comp.speech?

   Comp.speech is an unmoderated newsgroup for discussion of speech
   technology and speech science. It covers a wide range of issues from
   the application of speech technology, to research, to products and
   lots more. By its nature, speech technology is an inter-disciplinary
   field and the newsgroup reflects this. However, computer application
   is the basic theme of the group.

   Note: If you don't know what a newsgroup is, then talk to your local
   system administration about how to get access. A useful newsgroups for
   beginners is news.announce.newusers. You might also find the following
   documents useful.





   The following is a list of some of the topics covered by comp.speech.

     * Speech Recognition - discussion of methodologies, training,
       techniques, results and applications. This should cover the
       application of techniques including HMMs, neural-nets and so on to

                         Q1.7: Speech databases

   A wide range of speech databases have been collected. These databases
   are primarily for the development of speech synthesis/recognition and
   for linguistic research.

   Some databases are free but most are not. The databases normally
   require lots of storage space (100's of MBytes is not unusual). Do not
   expect to be able to ftp large amounts of speech data.

   In addition to the descriptions of speech databases and speech
   database providers below, information can be obtained from

    LDC: Linguistic Data Consortium
          Provides a very wide range of speech and text data to research
          and commercial users: see below.

        ERBA: 10000 utterances from a train inquiry task

     * Misc: BAS is currently developing tools for the automatic
       annotation and segmentation of very large speech corpora. This
       includes the automatic detection of variants of pronunciation, a
       statistical based alignment and a rule-based refinement of the
       outcome. The BAS seeks to cooperate with public institutions as
       well as with industrial partners to further develop new German
       speech databases. BAS can be a platform to re-distribute existing
       German speech.

  UCLA Sounds of the World's Languages

     * Description: The UCLA Sounds of the World's Languages are
       available for Macintosh users (no DOS based system currently
       available). The sounds are stored in a Hypercard database
       developed at the UCLA Phonetics Laboratory. The aim is to
       illustrate and teach about the range of sounds used in human
       languages with material on more than 80 languages. The set
       demonstrates particular highlights of the sound systems focusing
       especially on rarer sounds that students may not otherwise have a
       chance to hear from a native speaker. The recordings are based on
       the archives of recordings collected at UCLA, with additional
       contributions from outside collaborators. All the languages can be
       accessed from the list of language names, or by clicking on the
       language name in a set of maps. Support for part of this work was
       provided by NSF. The database currently includes examples of
       languages from Agul and Akan to Zulu.

         Q1.9: Speech Laboratory Environments and Audio Editors

   First, what is a Speech Laboratory Environment? A speech lab is a
   software package which provides the capability of recording, playing,
   analysing, processing, displaying and storing speech. Your computer
   will require audio input/output capability. The different packages
   vary greatly in features and capability - best to know what you want
   before you start looking around.

   Most general purpose audio editing packages will be able to process
   speech but do not necessarily have some specialised capabilities for
   speech (e.g. formant analysis).

   The following article provides a good survey.

     * Description: Ptolemy provides a highly flexible foundation for the
       specification, simulation, and rapid prototyping of systems. It is
       an object oriented framework within which diverse models of
       computation can co-exist and interact. Ptolemy can be used to
       model entire systems.
       Ptolemy has been used for a broad range of applications including
       signal processing, telecomunications, parallel processing,
       wireless communications, network design, radio astronomy, real
       time systems, and hardware/software co-design. Ptolemy has also
       been used as a lab for signal processing and communications
       courses. Ptolemy has been developed at UC Berkeley over the past 3
       years. Further information, including papers and the complete
       release notes, is available from the FTP site.

Quadravox Speech Processing Products - Qbox

     * Platform: Windows 3.1, Windows 95
     * Description: Qbox comprises a Windows-based LPC-12 analysis and
       editing sytem and a parallel-port driven programmer for
       one-time-programmable TI TSP50P11 synthesis chips. The analysis
       software utilizes standard 11025Hz, 16bit monaural .wav files for
       input and allows graphical editing of the coded pitch, gain, and
       reflection coefficients. It can also be used to define
       concatenation sequences of individual phrases. Data rates depend
       on the original sound, but are typically below 2000bits/sec. The
       processed data can then be merged with synthesis and control
       routines and programmed into the TI synthesizer. The
       Quadravox-developed synthesis routine accepts run-time
       modifications of pitch and frame-length (speed), as well as
       externally defined concatenation sequences. The synthesis chip
       interface can be defined as a matrixed-keyboard drive, a simple
       parallel control, or a serial bus control supporting up to 31
       individually addressed devices and modules.

ASAPI: Advanced Speech API (AT&T)

     * Description: The AT&T ASAPI Specification is a open,
       cross-platform, easy-to-use speech API that can support speech
       engines from AT&T and other vendors. ASAPI does not replace the
       Microsoft Speech API, but it provides extensions and enhancements
       to the Microsoft SAPI Specification including support for
       SAPI-compatible applications.
       The ASAPI Specification defines two types of interfaces. The
       "ASAPI Extensions" interface which provides extensions to the
       MS-SAPI interface as well as C++ class encapsulation of SAPI
       functionality. The "Visual ASAPI" interface provides an even
       higher-level abstraction of SAPI/ASAPI low-level functionality
       such that application developers can quickly and easily embed
       speech technology into existing or new applications. Special
       Purpose Recognizers are examples of Visual ASAPI interfaces which
       integrate lower-level functionality that an application developer
       can access via a simple interface.
     * More information: Contact Jose Garcia at AT&T on (908) 957-5457 or

Nautilus: Secure Computer Telephony

     * Platform: DOS, Linux, SunOS, Solaris.
     * Description: Nautilus is software which allows two users to hold a
       secure conversation with either over ordinary phone lines or over
       a computer network. Nautilus uses your computer's audio hardware
       to digitize and play back your speech using speech compression
       algorithms built into the program. It encrypts the compressed
       speech using your choice of the Blowfish, Triple DES, or IDEA
       block ciphers, and transmits the encrypted packets over the
       internet or your modem to another computer. At the other end, the
       process is reversed. Nautilus operates in half duplex mode like a
