AppTek’s flagship Automatic Speech Recognition (ASR) solution, PlainSpeech, provides advanced speech recognition for dictation, broadcast, and telephony. This highly reliable ASR manages almost any speech recognition task, from simple chain of numbers recognition and complete call center solutions to information retrieval with vocabularies of 100,000 or more words.The result of years of research experience on the man-machine interface at the Aachen Institute of Technology, PlainSpeech forms the basis for many individually tailored automatic speech recognition systems that can be easily integrated into customer products. PlainSpeech features include:  Automatic Speech Recognition for Dictation, Broadcast, and Telephony
Command Word RecognitionHigh speed and remarkably low error rates characterize the PlainSpeech automatic speech recognition for small vocabularies. The system can easily be expanded any time with new commands to adapt to changing needs and demands.Applications include:
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. Qualified employees can concentrate on their primary tasks in providing customer service. PlainSpeech efficiently processes customer dialogues and makes it easy for customers to navigate telephone information and ordering systems.Recognition of Continuous SpeechThanks to its scalability, AppTek’s automatic speech recognition engine can also be expanded into a dictation system with a large vocabulary. Especially good results are achieved with solutions tailored for specific sectors. Performance and quality are assured through the use of the newest speech and grammar models. Additional features include voice-to-email or voice-to-SMS. Multilingual Information Retrieval: In light of the many languages used on the World Wide Web, a language-independent system can help users avoid being limited to their mother tongue. AppTek is currently developing such a self-learning system. Multilingual Information Retrieval makes it possible to ask questions pertaining to a particular topic, find relevant documents in other languages, and summarize and translate these into the desired language. All relevant information becomes accessible and comprehensible for the user. The system is initially being developed for the 11 EU languages, and will be expanded to other languages. Spoken Document Retrieval: The basis for this application is the combination of PlainSpeech automatic speech recognition with modules for text classification and extraction from AppTek Knowledge Management. The system improves the use of audio databases. For example, Internet users can find spoken news, and media companies can perform automated searches of their archives. Searches can be entered in text in the usual manner. A combination of the ASR product PlainSpeech with AppTek’s TranSphere machine translation modules, creates a speech-to-speech translation system. An award-winning element of the VERBMOBIL project, this system enables automatic live translation for specific content domains. AppTek’s collection of languages and supported content domains grows continuously.
