Speaking in the presence of a competing talker

چکیده
How do speakers cope with a competing talker? This study investigated the possibility that speakers are able to retime their contributions to take advantages of temporal fluctuations in the background, reducing any adverse effects for an interlocutor. Speech was produced in quiet, competing talker, modulated noise and stationary backgrounds, with and without a communicative task. An analysis of the timing of contributions relative to the background indicated a significantly reduced chance of overlapping for the modulated noise backgrounds relative to quiet, with competing speech resulting in the least overlap. Strong evidence for an active overlap avoidance strategy is presented.

Monaural speech separation and recognition challenge
Robust speech recognition in everyday conditions requires the solution to a number of challenging problems, not least the ability to handle multiple sound sources. The specific case of speech recognition in the presence of a competing talker has been studied for several decades, resulting in a number of quite distinct algorithmic solutions whose focus ranges from modeling both target and compet...

PURPOSE It is established that speaking clearly is an effective means of enhancing intelligibility. Because any signal-processing scheme modeled after known acoustic-phonetic features of clear speech will likely affect both target and competing speech, it is important to understand how speech recognition is affected when a competing speech signal is also spoken clearly. In 2 experiments, the au...

How do talkers maintain intelligibility when speaking in the presence of a background conversation? The current study identified acoustic and temporal modifications of speech manifested by interlocutors in the face of competing speech, with and without visual contact. Pairs of talkers held free conversations either alone or in the presence of a second pair. Regardless of the availability of vis...
متن کاملEffects of Hearing Loss and Cognitive Load on Speech Recognition with Competing Talkers
Everyday communication frequently comprises situations with more than one talker speaking at a time. These situations are challenging since they pose high attentional and memory demands placing cognitive load on the listener. Hearing impairment additionally exacerbates communication problems under these circumstances. We examined the effects of hearing loss and attention tasks on speech recogni...
متن کاملEffect of informational content of noise on speech representation in the aging midbrain and cortex.
The ability to understand speech is significantly degraded by aging, particularly in noisy environments. One way that older adults cope with this hearing difficulty is through the use of contextual cues. Several behavioral studies have shown that older adults are better at following a conversation when the target speech signal has high contextual content or when the background distractor is not...
