For Dictation Broadcast and Telephony
Speech is the most natural form of communication. Profit from years of
researchers at the Aachen Institute of Technology who have worked on the
between man and machine! Our modules form the basis for individually
recognition systems that are easily integrated into your products.
PlainSpeech offers a new technology that significantly improves and
simplifies the use
of technical products:
• Fast and reliable recognition of continuous speech
• User specified speaker-dependent or speaker-independent recognition
• Gender-independent speech recognition
• Scalable vocabulary, scalable number of recognized languages
• Grammar and speech models to improve speed and quality
• Dialogue guiding with dynamic database interface
The system manages almost any recognition
task: from simple number chain
recognition and complete call center solutions to information retrieval with
of 100,000 words or more.
High speed and remarkably low error rates characterize our speech
small vocabularies. The system can easily be expanded any time with new
to adapt to changing needs and demands.
Applications for this area are for example:
• Speech commissioning in logistics
• Checking and recording in quality assurance work
• Guidance and navigation interface for user terminals
• Speech driven consumer applications
Dialogue System / ''Interactive Voice Recognition (IVR)''
Dialogue systems are scalable.
Command word recognition modules can simulate dialogue processes well in a
decision tree structure. PlainSpeech provides sufficient freedom in the
definition of dialogue processes and provides reliable recognition even in
noisy environments. Lengthy dialogues that might occur in a call center can
also be accommodated. Standard questions can be answered by automatic
systems at any time of day. Qualified employees can concentrate on their
primary tasks in manning customer relations. PlainSpeech efficiently
processes customer dialogues and makes it easy for customers to navigate
telephone information and ordering
Recognition of continuous speech
Thanks to its scalability AppTek's speech recognition engine can also be
expanded into a dictation system with a large vocabulary. Especially good
results are achieved for tailored solutions for specific sectors.
Performance and quality are assured through the
use of the newest speech and grammar models. Further features include
voice-to-email or voice-to-SMS. One application for the recognition of
continuous speech is the Multilingual Information Retrieval: In light of the
many languages on the World
Wide Web, a language-independent system can help avoid being limited by
mother tongue. The development of such a self-learning system is another
task of AppTek.
Multilingual Information Retrieval makes it possible to ask questions
pertaining to a
particular topic, find relevant documents in other languages, summarize
these and translate them into the desired language. All relevant
information becomes accessible
and comprehensible for the user. The system is initially being developed for
relevant EU languages, and will later be expanded to other languages.
A further application is Spoken Document Retrieval: The basis for this
the combination of speech recognition PlainSpeech with modules for text
and extraction from the Knowledge Management area of AppTek.
The system improves the use of audio mediated databases. For example,
can find spoken news. Media companies can do automated searches of their
Searches can be entered in text in the usual manner. A combination of the
recognizer PlainSpeech with the modules from AppTek’s machine translation
creates a speech-to-speech translation system.
This system, that received awards as part of the VERBMOBIL project, enables
live translation for specific content domains. Our collection of languages
content domains grows continuously.
The PlainSpeech-system is a current generation self-learning
Supported platforms (Operating system, architecture):
Microsoft Windows NT, 2000, XP, Sun Sparc Solaris, Linux, StrongARM, XScale,
MacOSx, Power PC
Supported software interfaces / Standard-APIs: C/C++, Java, XML / SGML
Supported standards: VoiceXML, Salt, W3C-XML-Standards for grammar and
Speech Assessment Methods Phonetic Alphabet (SAMPA)
We offer the scalable possibility of using the following grammars to develop
Statistical grammar for commando word recognition, Finite State Automaton (FSA),
Standard n-gram and gap-n-gram language models, combinations of these
models, context free grammar models (CFG).
PlainSpeech.WAY is software that integrates telephone, computer and other
communications modes into one modern system. Through integrated speaker
independent speech recognition, the system receives all commands through

tailored to customer needs PlainSpeech.WAY can be used as an intelligent
that routes calls, takes messages, delivers information, interoperates with
databases, sends faxes, and much more. Each of these functions is
represented visually on the graphical user interface. The representation is
very user friendly and has a very steep learning curve. The user can set up
the various functions according to his own individualized needs.
The different functions are connected to each other and can be used as often
as necessary. A script can be developed for any scenario, and these are
easily edited and expanded.
Telephone switchboard – fully automated
Callers can now use speech commands to navigate such a script.
PlainSpeech.WAY recognizes spoken words and activates the desired function.
For example, after saying "Support" the caller is connected to the tech
support department of the company, or by saying "record a message" he can
leave a voicemail for an employee. The capabilities of speech recognition
also permit customers who don’t have touch-tone capabilities, or don’t want
to use these, to take advantage of modern telecommunications functions. The
ability to dial out by
usual methods remains – any function can be driven by speech commands or

switchboard – that meets any demand. The target person of a voicemail
can be informed by mobile phone of a message waiting immediately or at a
time specified by the recipient. Messages can also be forwarded by email
with a Wave attachment. Using caller-ID, messages can be routed in different
ways through personalized functions. This way reaching the appropriate
function is made more efficient.
An additional function allows users to launch other applications on a
computer through a script. For example, if an office security system is
controlled through a computer, this can be turned on and off through a phone
Functions that are not supposed to be freely accessible can be protected

application of PlainSpeech.WAY is by no means limited to a single script.
Depending on time of day different scripts can be used to
guide the dialogue with the caller and the PlainSpeech.WAY software. The
simplest example is to greet the caller with "Good morning" ,"Good
afternoon" or "Good evening“depending on what time it is.
Telephone switchboard – easily implemented
PlainSpeech.WAY can be used with any standard PC running Windows. The
connection between computer and phone line is made through an ISDN
