In this contribution various objective measures that can be used to evaluate speech dereverberation algorithms by means of listening-room compensation (LRC) are compared to subjective listening tests. It is shown that technical measures describing the impulse responses are suitable for evaluation of such algorithms. Most signal-based objective measures fail(More)
Hands-free communication devices are commonly used e.g. in offices or car environments. These devices have to cope with several problems such as ambient noise, acoustic echoes and room reverberation. Reverberation is caused by reflections at room boundaries in enclosed spaces and increases with the spatial distance between the loudspeaker and the near-end(More)
In this contribution objective measures for quality assessment of speech signals are evaluated for listening-room compensation algorithms. Dereverberation of speech signals by means of equalization of the room impulse response and reverberation suppression has been an active research topic within the last years. However, no commonly accepted objective(More)
