Speech Recognition and Natural Language Understanding Training Course
Course Overview
This course focuses on the integration of speech recognition and natural language understanding (NLU) techniques to develop robust voice-based AI systems. Participants will explore the fundamentals of automatic speech recognition (ASR), language models, and intent recognition using frameworks like Kaldi, CMU Sphinx, and Python-based libraries. Hands-on labs and real-world applications will enable attendees to build and deploy speech-enabled systems with confidence.
