Stuttering identification is an interesting interdisciplinary domain research problem which involves pathology, psychology, acoustics, and signal processing that makes it hard and complicated to detect. Recent developments in machine and deep learning have dramatically revolutionized speech domain, however minimal attention has been given to stuttering identification. This work fills the gap by tryingto bring researchers together from interdisciplinary fields. In this paper, we review comprehensively acoustic features, statistical and deep learning based stuttering/disfluency classification methods. We also present several challenges and possible future directions. CCS Concepts: • Computing methodologies ! Artificial intelligence; Machine learning; Natural language processing. Additional Key Words and Phrases: speech disfluency, stuttering detection, datasets, features, modality, machine learning, deep learning, challenges, future directions.

These disorders can take the form of dysarthria, apraxia, stuttering, cluttering, lisping, and so on [1–5].
