Abstract:
Recognition of sentences containing periodic, 5-Hz, silent interruptions of differing duty cycles was assessed for three types of processed speech. Processing conditions employed different combinations of spectral resolution and the availability of fundamental frequency (F0) information, chosen to yield similar, below-ceiling performance for uninterrupted speech. Performance declined with decreasing duty cycle similarly for each processing condition, suggesting that, at least for certain forms of speech processing and interruption rates, performance with interrupted speech may reflect that obtained with uninterrupted speech. This highlights the difficulty in interpreting differences in interrupted speech performance across conditions for which uninterrupted performance is at ceiling.

01:10Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...

Communication barriers include the following:
Physiological barriers: They are limitations caused by a person's health condition or disability, such as hearing loss, poor eyesight, illness, or unconsciousness. An example to overcome this...
01:10Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

Interference occurs when competing memories hinder the retrieval of particular information. It can be classified into two types: proactive and retroactive interference. Proactive...
01:06Echo
Imagine the sound is reflected back to the ears. Assuming that the source is very close to the human, the difference between hearing the two sounds—the emitted sound and the reflected sound—may be more than the minimum time for perceiving distinct sounds. If this is the case,...

Cultural barriers:
Differences in values, beliefs, religion, knowledge, and tradition can significantly impact communication. Awareness of nonverbal cues is critical, especially when conversing with a patient from a different culture. What appears appropriate in one culture may be inappropriate in another.
Semantic barriers:
As a result of their tendency to use...
