Which Response Is Not a Challenge Engineers Faced in Designing

question 6

Multiple Choice

Which response is not a challenge engineers faced in designing automated speech recognition software?

• A) The stream of speech sounds proceeds without many silences, making it hard to decide when the signal has ended one word and begun the next word.
• B) Individual speakers vary widely in how they pronounce phonemes.
• C) Even a voice-activated toy dog must understand the meaning of individual words if it is to respond differently to each of them.

Test-Retest Reliability

The degree to which a test yields the same results when it is given more than once to the same person. Test-retest reliability can be evaluated by correlating a person’s score on a given test with the same person’s score on the same test taken at a later time. The higher the correlation between the two scores (as expressed in terms of a correlation coefficient) the more reliable it is.

Psychological Test

A standardized instrument or systematic procedure designed to evaluate a specific aspect of an individual's mental health, intelligence, or aptitude.
