  1. RoboTechTronix • Ryan Fonnesbeck (CS and CE) • Brian Clay (CE) • Justin Hansen (CE)

  2. Project Description • Voice Interactive Robot • Recognize voice commands. • Recognize trained keywords or expressions. • Respond to voice commands. • Verbal feedback and interaction with the user. • Non-verbal feedback such as navigation.

  3. The Use of Nueral Networks • Neural Networks use a set of processing elements loosely analogous to neurons in the brain. These nodes are interconnected in a network that can then identify patterns in data as it is exposed to the data. • After first processing audible data as discrete sound frequencies, data is pumped through a series of Fourier transformations and then sent to a neural network for processing. This complex and sophisticated process allows us to successfully perform speech recognition.

  4. Project Motivations • Useful • natural interface • Push Limits of Technology • real time natural processing • Cool.

  5. Project Overview • Voice Interactive Robot • JStamp – Real-time native execution Java hardware and software micro-controller. • VoiceDirect 364 – State-of-the-art speech recognition technology. • ChipCorder 2560 – Single-chip record/playback technology. • Motorola 6210 – Two-way radio. • LM4863 – Audio amplifier.

  6. Functional Partition • Implemented a serial protocol using the JStamp I/O pins and VoiceDirect 364 I/O pins. • Utilized JStamp I/O pins and VoiceDirect 364 I/O pins to control the ChipCorder 2560.

  7. Software Flow Chart • Packaged software to allow others to easily re-use and implement their own voice interactive robot. • Software modes allow for run-time hardware configuration.

  8. Problems Encountered • Operational range for the VoiceDirect 364 • Baby Monitor • Walkie-talkies • Voice recognition accuracy • Noise filtering • VoiceDirect 364 configuration • Speaker dependent vs. Speaker Independent • Number of words vs. accuracy • VoiceDirect 364 Serial Protocol Latency • Time constraints

  9. Conclusions • Plan • Initial project plan • Limitation of Current Voice Recognition technology • Importance of documentation

  10. Demonstration

  11. Questions • ???
