The course teaches feature mapping approaches, neural voice conversion models, and speaker adaptation techniques for ASR. Students learn how to handle speaker variability while preserving linguistic content.
Unique: Treats voice conversion and speaker adaptation as related problems of speaker variability management, teaching both feature-mapping and neural approaches. Emphasizes the linguistic-paralinguistic trade-off in voice transformation.
vs alternatives: More specialized than general speech processing courses; more practical than pure speaker modeling courses
Teaches the design and implementation of language models (LMs) specifically for speech recognition and spoken language understanding tasks. The course covers n-gram models, neural language models (RNNs, Transformers), and their integration into ASR decoding. Students learn how LM probability estimates constrain the acoustic decoder's search space and how to evaluate LM quality using perplexity and downstream ASR metrics.
Unique: Focuses specifically on LM design for speech (not general NLP), emphasizing the coupling between acoustic and language model scores during decoding. Teaches both classical n-gram approaches and modern neural LMs with practical integration into ASR systems.
vs alternatives: More speech-specific than general NLP language modeling courses; more practical than theoretical LM courses that don't address ASR integration
Teaches methods for extracting meaning from spoken input, including intent detection, slot filling, and semantic frame parsing. The course covers how to map spoken utterances to structured semantic representations (e.g., dialogue acts, semantic frames) using both rule-based and neural approaches. Students learn to handle speech-specific challenges like disfluencies, repairs, and acoustic ambiguities in semantic understanding.
Unique: Emphasizes the unique challenges of understanding spoken language (ASR errors, disfluencies, repairs) rather than treating speech as clean text. Teaches both rule-based semantic grammars and neural sequence labeling/classification approaches tailored for speech.
vs alternatives: More speech-aware than general NLU courses; more practical than pure semantic parsing courses that ignore speech-specific error modes
Covers the architecture and implementation of dialogue systems that interact through spoken language, including dialogue state tracking, dialogue management, and response generation. The course teaches how to design dialogue flows, manage conversation context, and integrate ASR, NLU, and natural language generation (NLG) components. Students learn both task-oriented dialogue (slot-filling) and more open-ended conversational approaches.
Unique: Teaches dialogue system architecture as an integrated pipeline combining speech, language, and dialogue components. Emphasizes dialogue state tracking and management strategies rather than treating dialogue as a simple input-output mapping.
vs alternatives: More comprehensive than chatbot frameworks that abstract away dialogue management; more practical than pure dialogue theory courses
