Presentation Transcript

  1. Speech • Language is a miracle. • And speech is one of realizations of language. • The evolution of culture, science, literature... • Speech is a basic component in the formation “society” • Speech is communication of humans (not the only one...) • Speech allows distant communication (more “live” than writing)

  2. Speech Communication Involves • Thought  linguistics: language, semantics, emotion, style • Production and listening  physiology, physics • Transmission  Physics, acoustics • Transmission  engineering, mathematics, speech science/engineering, computing, industry, management
