Final answer:
Live voice testing is time-consuming, may result in difficulty eliciting participant response, and may not accurately capture real-life behaviors.
Step-by-step explanation:
One disadvantage to live voice testing is that it can be time consuming. This means that the process can require a significant amount of time, both in preparation and execution, which may not be ideal for situations where quick assessments are necessary. Additionally, it can be difficult to encourage participant response, as some individuals may feel self-conscious or reluctant to speak in a testing environment, which can skew the results.
Moreover, live voice testing captures what people think and believe but not necessarily how they behave in real life, which can lead to discrepancies between the test outcomes and actual behavior patterns.
