Q2. What is the way to test candidates for human-likeness?
In other words, tests for response implicitly test perception and understandingas well, but as response tests are considerably more expensive, it is prudent to test candidates using perception and understanding tests first.
Q3. What are some examples of features that can be accessed from SAD decisions?
Examples of such features include different durations, such as the lengths of pauses, overlapping speech and utterances, which can be accessed using speech activity detection; prosodic features, such as intensity and pitch; and turn-taking patterns, which can be accessed from SAD decisions and an interaction model (e.g. Brady, 1968).
Q4. What is the example of a machine that can make a human believe she is talking?
Nigel Ward’s humming machine (Ward & Tsukahara, 2000) is an example of a machine that can potentially make a human believe she is talking to another human, if presented in an appropriate context – like a telephone conversation where one person does most of the talking.
Q5. What was the lack of realism in traditional wizard-of-oz collections?
the lack of realism in traditional Wizard-of-Oz collections, a method which was coined in-service Wizard-of-Oz data collection was introduced, in which the wizards were real customer care operators and the callers were real customers with real problems.
Q6. What is the way to use wizards to aid a spoken dialogue system?
If the wizards are allowed to use whatever means they are given to the best of their ability and any restrictions imposed on them are encoded in the software, then the wizards’ actions represent the target the component designer should aim at – an idea akin to Paek (2001), who suggests using human wizards’ behaviour as a gold standard for dialogue components.
Q7. What are some of the more novel twists in human-like spoken dialogue?
Other more novel twists include manipulating human-human dialogues on-line, effectively treating both participants as subjects and recording continuous judgments of some parameter by a panel of reviewers equipped with different kinds of audience response systems.
Q8. What is the main argument for human-likeness in spoken dialogue systems?
There is also a growing interest for human-likeness in spoken dialogue systems amongst researchers (e.g. Philips, 2006, keynote speech, Interspeech, Pittsburgh, PA, US; Zue, 2007), and many researchers have made a case for anthropomorphism in spoken dialogue systems.
Q9. Why is the uncanny valley not known to us?
For one thing, no reports of uncanny valley effects from users actually interacting with human-like spoken dialogue systems are known to us, possibly because spoken dialogue systems aiming at human-likeness are yet too immature.
