In-car dialogue systems typically resemble non-co-located conversations more, and share their negative impact (Strayer et al., 2013). We implemented and tested a simple strategy for making in-car dialogue systems aware of the driving situation, by giving them the capability to interrupt themselves when a dangerous situation is detected,and resume when over. We show that this improves both driving performance and recall of system-presented information, compared to a non-adaptive strategy.

In the case of holding conversations, a human passenger who is aware of the driving conditions can choose to interrupt his speech in situations potentially requiring more attention from the driver, but in-car information systems typically do not exhibit such sensitivity. We have designed and tested such a system in a driving simulation environment. Unlike other systems, our system delivers information via speech (calendar entries with scheduled meetings) but is able to react to signals from the environment to interrupt when the driver needs to be fully attentive to the driving task and subsequently resume its delivery. Distraction is measured by a secondary short-term memory task. In both tasks, drivers perform significantly worse when the system does not adapt its speech, while they perform equally well to control conditions (no concurrent task) when the system intelligently interrupts and resumes.

In-car dialogue systems ignore these important aspects, making them more distracting than even cell-phone conversations. We developed and tested a "situationally-aware" dialogue system that can interrupt its speech when a situation which requires more attention from the driver is detected, and can resume when driving conditions return to normal. Furthermore, our system allows driver-controlled resumption of interrupted speech via verbal or visual cues (head nods). Over two experiments, we found that the situationally-aware spoken dialogue system improves driving performance and attention to the speech content, while driver-controlled speech resumption does not hinder performance in either of these two tasks Y1 - 2014 SN - 9781450328852 U6 - https://doi.org/10.1145/2663204.2663244 SP - 26 EP - 33 PB - ACM CY - New York, NY ER - TY - GEN A1 - Kempf, Sabrina A1 - Bieber, Claudia A1 - Corsten, Sabine A1 - Lutz-Kopp, Matthias A1 - Heim, Stefan A1 - Lauer, Norina T1 - Mitbetroffen von Aphasie: Die subjektiv empfundene Lebensqualität der Angehörigen von Menschen mit Aphasie BT - Poster T2 - Jahrestagung der Gesellschaft für Aphasieforschung und -behandlung (GAB), Tagungsband N2 - Als Systemerkrankung beeinflusst die neurologische Sprachstörung Aphasie nicht nur die Betroffenen sondern in vergleichbarem Maße auch die Angehörigen. Es zeigt sich, dass die Lebensqualität der Angehörigen beeinträchtigt ist. Ziel der qualitativen Studie ist es, die subjektive Perspektive der Angehörigen auf die eigene Situation näher zu betrachten.

Typical dialogue systems are not receptive and cannot adapt while uttering. We present combin-able components for incremental natural lan-guage generation and incremental speech syn-thesis and demonstrate the flexibility they can achieve with an example system that adapts to a listener's acoustic understanding problems by pausing, repeating and possibly rephrasing problematic parts of an utterance. In an evaluation, this system was rated as significantly more natural than two systems representing the current state of the art that either ignore the interrupting event or just pause; it also has a lower response time.

We focus on the ‘middleware’ layer in these systems, which takes care of passing around and maintaining incremental information between the modules of such agents. All implementations are based on the abstract model of incremental dialogue processing proposed by Schlangen and Skantze (2009), and the paper shows what different instantiations of the model can look like given specific requirements and application areas.

A procedural system supporting a limited number of emotional expression changes was created alongside keyframed animations of these same emotional expression changes, and audience response to these two approaches was tested empirically. Results seem to partially support the procedural animations generated being comparable with keyframed, in terms of perceptual validity.
