Tutorial 5: Vocal Dialogue Management: Frame-Based Approaches

This tutorial description has been updated

Ivan Kopecek, Masaryk University, Brno, Czech Republic and Martin Rajman, EPFL, Lausanne, Switzerland

The goal of this tutorial is to introduce an approach to human-machine dialogue management that is based on frame-based dialogue models; the connections with current industrial standards such as VoiceXML, as well as the use of rapid dialogue development tools, will be presented. The various techniques will be illustrated during two practicals: one focusing on VoiceXML-based dialogues (implementation of the best strategy to the prisoners' dilemma) and one on rapid dialogue prototyping using the EPFL dialogue platform (building a simple dialogue system for controlling the home by voice).

Troubleshooting speech recognition

  • Microphone input
    • Your microphone should be plugged in to the SOUNDCARD microphone input on the back of the machine (pink socket, near the bottom of the machine), and not the onboard sound microphone input.
  • Microsoft speech recognition setup
    • Using the speech recognition taskbar icon, which is a picture of microphone over a page of text (this will either be on the taskbar, or accessed via the "EN" icon on the taskbar), right click and select "Options"
      • On the Speech Recognition tab
        • Tell it which microphone input to use: Creative Sound Blaster PCI
        • Click "Configure microphone" and follow instructions
        • Optionally, click "Train" and follow instructions
