A multi-talker paradigm is introduced that uses different attentional processes to adjust speech recognition scores with the goal to conduct measurements at high signal-to-noise ratios. The basic idea is to simulate a group conversation with three talkers and a participant. Talkers alternately speak sentences of the German matrix test OLSA. Each time a sentence begins with the name"Kerstin"(call sign), the participant is addressed and instructed to repeat the last words of all sentences from… Expand

Effect of Speech Rate on Neural Tracking of Speech
TLDR
No relation was found between neural tracking and listening effort, even though both measures were clearly influenced by speech rate, and a shorter latency for faster sentences, which may reflect a neural adaptation to the rate of the input. Expand
Age-Related Changes in Listening Effort for Various Types of Masker Noises
TLDR
Findings from the present study indicate that older adults require more cognitive resources than younger adults to understand speech in background noise. Expand
Static and dynamic cocktail party listening in younger and older adults
TLDR
It is confirmed that dynamic cocktail party listening is associated with costs that depend on the type and probability of target switches, and further shows that, despite comparable costs of dynamic listening, mechanisms are different for the two age groups, as switching auditory attention is preserved with aging, but monitoring different sound sources appears to be more difficult for older adults.

The Impact of Noise and Hearing Loss on the Processing of Simultaneous Sentences
TLDR
Tasks involving the processing of simultaneous messages may be useful for assessing hearing handicap and the benefits of rehabilitation in realistic listening scenarios and are more sensitive to noise and hearing impairment than the ability to process a primary message. Expand
The benefit of binaural hearing in a cocktail party: effect of location and type of interferer.
TLDR
Data suggest that the benefit of binaural hearing for speech intelligibility is especially pronounced when there are multiple voiced interferers at different locations from the target, regardless of spatial configuration; measurements with fewer or with other types of interferers can underestimate this benefit.

Measuring Speech Recognition With a Matrix Test Using Synthetic Speech
TLDR
The outcomes of this study indicate that the application of synthetic speech in speech recognition tests could considerably reduce the development costs and evaluation time and offer the opportunity to increase the speech corpus forspeech recognition tests with acceptable effort. Expand

TLDR
In this experiment, the intelligibility of a target phrase masked by a single competing masker phrase was measured as a function of signal-to-noise ratio (SNR) with same-talker, same-sex, and different-sex target and masker voices. Expand
Low background noise increases cognitive load in older adults listening to competing speech.
TLDR
A dual-task paradigm sensitive to noise masking at favorable signal-to-noise ratios (SNRs) showed a significant SNR effect that was related to the listener's working memory capacity, suggesting that even subtle noisemasking causes cognitive load in competing-talker situations. Expand
The influence of informational masking in reverberant, multi-talker environments.
TLDR
IM related to target-masker confusions, at least for normal-hearing listeners, is of low relevance in real-life listening, and SRTs improved for the spatially distributed conditions compared to the colocated conditions. Expand
How competing speech interferes with speech comprehension in everyday listening situations.
TLDR
What is known about informational masking of speech by competing speech, and the auditory and cognitive factors that determine its severity are reviewed. Expand
