Speaker Recognition with Correlation Dimension

• Results suggest that correlation dimension doesn’t provide any speaker specific information

• Still running experiments with adjusted parameters.

Thesis

• Originally planned to focus on speaker recognition with invariant features

• Preliminary findings suggest that invariants may not provide speaker-specific information for all types of speech.
