Research: Real-time Simulation of acoustic Environments and automatic Evaluation of Speech Communication Systems

Speech Communication Systems, such as in-car communication (ICC) systems or communication units in fire-fighter masks, have become an integral part of modern life. Entire industrial sectors are devoted to the development and improvement of these systems. In addition to voice transmission, the main task of such systems is the improvement of speech intelligibility and speech quality. The voice communication systems use various signal processing techniques, e.g. noise reduction and echo cancelling techniques, to improve speech quality. They are able to deliver good results even in relatively disturbed environments. In order to evaluate the performance of the systems and make them comparable, standardized evaluation procedures must be developed. Both subjective and objective test methods are available for this purpose. Due to the reliability and reproducibility of the test results, the emphasis is placed on objective tests. Another important aspect of the evaluation is the reproducibility of suitable test scenarios. This requires a corresponding acoustic environment simulation, which is capable to simulate the acoustic properties of any location in a semi-anechoic chamber or even in an arbitrary, yet silent location. The main purpose of the acoustic environment simulation is the simulation of statistical properties of the acoustic signals. The acoustic simulation dispenses with the use of complex and expensive spatial acoustic reproduction methods, such the wave field synthesis. The goal is the reduction of the required channels and thus also the range in which a precise acoustic simulation can be ensured which does not lead to any drawbacks in most applications.
