Measuring passers-by engagement with AmPost: a printed interactive audio poster

This paper presents AmPost, a prototype of an interactive audio poster, which integrates ink-jet printed sonic and tactile elements along with textual and graphical information. This enables users to directly interact and engage with the poster. To achieve a seamless paper-based interactive poster that includes printed interactive elements, we implement a printed speaker and audio feedback system directly into the paper-based medium, which plays a short tune when someone walks by. Engaging passers-by with this new interface becomes a challenge as posters, in general, are non-interactive. This paper also presents an initial empirical evaluation of AmPost that captures and analyses the frequency and length of user engagement, and evaluates whether user engagement improves with the integration of interactive features, in comparison to the traditional non-interactive poster. This study facilitates in building the generic approach to measure engagement that applies to any kind of posters.

Speaker identification using higher order spectral phase features and their effectiveness vis-a-vis Mel-Cepstral features

The effectiveness of higher-order spectral (HOS) phase features in speaker recognition is investigated by comparison with Mel Cepstral features on the same speech data. HOS phase features retain phase information from the Fourier spectrum unlikeMel–frequency Cepstral coefficients (MFCC). Gaussian mixture models are constructed from Mel– Cepstral features and HOS features, respectively, for the same data from various speakers in the Switchboard telephone Speech Corpus. Feature clusters, model parameters and classification performance are analyzed. HOS phase features on their own provide a correct identification rate of about 97% on the chosen subset of the corpus. This is the same level of accuracy as provided by MFCCs. Cluster plots and model parameters are compared to show that HOS phase features can provide complementary information to better discriminate between speakers.
