Speech research is a field of study that focuses on the understanding, creation, and analysis of human speech. This can include a variety of topics such as speech production and perception, speech recognition, speech synthesis, speech processing, and phonetics. Researchers in this area may use techniques from linguistics, psychology, computer science, and engineering to explore how speech is produced and understood by humans, as well as how machines can be designed to interpret and generate speech. The ultimate goal of speech research is to improve communication between humans and machines, as well as advance our understanding of the complexities of language and speech.
