A laboratory model of the wireless "Communications EarPlug" (w-CEP) was developed. Standard communication earplugs (using wires) are known to offer relatively good intelligibility of intercom speech at high ambient noise levels. The intercom sound is produced by means of a commercially available miniature transducer, integrated in the earplug....

The speech intelligibility and quality of a MELP low bitrate speech coder (1200 bps) were investigated in an experiment, in which the speech coder was either combined with or without a noise pre-processing system. The central question to be addressed was to what extent the performance of the speech coder could be improved by adding a noise pre...

It is in most cases relatively easy to understand one talker even if other persons arc talking at the same time. Over the last decades, this so-called cocktail party phenomenon has been the subject of a considerable number of studies. In the present paper, an overview is given of part of this research, specifically those studies dealing with the...

In a 3D auditory display sounds are presented over headphones in a way that they seem to originate from virtual sources in a space around the listener. This paper describes a study on the possible merits of such a display for bandlimited speech with respect to intelligibility and talker recognition against a background of competing voices....

Current objective measures for predicting the intelligibility of speech by an index assume that this can be obtained by simple addition of the contributions of individual frequency bands. The Articulation Index (AI, and the related Speech Intelligibility Index), and the Speech Transmission Index (STI) are based on this assumption. There is...

The article deals with the question of why multichannel amplitude compression appears to have a negative rather than a positive effect no speech intelligibility by hearing-impaired listeners. It is argued that the small time constants of amplitude compression diminish the temporal as well as the spectral contrasts in the speech signal. According...

A physical method for measuring the quality of speech‐transmission channels has been developed. Essentially, the method represents an extension of the Articulation Index (AI) concept, which was developed mainly to account for distortions in the frequency domain (noise, bandpass‐limiting). The underlying concept of the present approach, based on...
