Come and attend a one-day user group meeting that covers the topic of evaluating speech quality of hands-free communication systems used inside of automobiles. Speech quality for in-vehicle hands-free applications is a challenging topic as the hands-free terminals inside a vehicle have to work under different and difficult acoustical conditions. Optimum speech intelligibility and speech quality has to be provided in the sending and the receiving direction, while being subjected to double talk and background noise conditions. Basic theories and procedures for quantification and optimization of hands-free terminals inside a vehicle will be presented using the HEAD acoustics ACQUA system and the specification of the German automotive industry VDA "specification for hands-free terminals". Furthermore, test configurations for testing voice recognition systems are introduced and discussed. About VDA:The VDA standard is widely accepted as the only requirement insuring good acoustic quality of HandsFree terminals in car. VDA was started from a need expressed by German auto manufacturer; HEAD acoustics was contacted to help in this project as the acoustic expert, and contributed largely to the definition of requirements. VDA now becomes an international standard. ITU is working on developing a new standard based on VDA. User Group Meeting Agenda
About HEAD acousticsHEAD acoustics was started in 1986 with the aim of establishing a new standard in the area of artificial head-related recording and playback technology. Since then, HEAD acoustics has established itself as a leader in the field of telecommunications engineering. The company has developed special measurement and analysis techniques for determination of the transfer characteristics of voice controlled systems, which have paved the way for the investigation and optimization of speech quality in communication networks. HEAD acoustics is committed to providing excellent technical support and repair and calibration services for products used in the telecom area. About the PresenterDr. Hans Gierlich is the head of the Telecom division of HEAD acoustics GmbH, Aachen, Germany. He is responsible for the development of acoustic measurement systems used in the field of telecommunications. His specialty is in the area of psychoacoustics, binaural simulation, measurement technology and speech transmission in telecommunication. His main activities are in the fields of speech intelligibility and speech quality especially in modern telecommunications systems, binaural signal processing, especially binaural simulation technology, and digital signal processing. He is active in the international standardization organizations ITU-T, ISO, ETSI, 3GPP and IEEE as well as in the German standardization organization DIN. He is currently involved in various European projects. Dr. Gierlich is the author of more than 100 scientific papers in the field of binaural technology, telecommunications, and signal processing published in various magazines and proceedings. He holds three patents in the field of telecommunications and two patents in binaural technology. Time, Date and Location:The ACQUA User Group Meeting will run from 8:30 AM to 4:30 PM on Wednesday, June 20, 2007. The meeting will be held in our Brighton, Michigan office. Lunch will be provided to attendees.
