Submission procedure explained below.
3. For each of the following TTS interactive demo sites: ATT, IBM, Nuance, test at least 2 voices for languages you know. Save input text and output .wav files, appropriately marked, together with the conclusions you draw from each. Note the major errors you discover.
4. Provide an overall assessment of each TTS system and, within the system, of the voices you test. What are the major strengths and weakness? Which is the best system/voice?
1. Propose a set of criteria for evaluating Spoken Dialogue Systems. Again, these criteria should be as objective and results as reproducible as possible. Try to exercise as many components of the system as possible. In addition to evaluating the performance of the TTS and ASR components, your criteria should include specific ways to evaluate the dialogue manager. Use your criteria to evaluate the following systems, providing an overall assessment of each system, and an explicit comparison between the systems.
a. Call the TellMe speech recognizer. The number is 1-800-555-TELL
b. Call the United Airlines automatic flight information, at 1-800-824-6200
