Speech Communication

Speech Communication Technical Committee

Scope of Scientific Activities 

We are a special-interest group of about 950 scientists within the ASA concerned with the study of the production, transmission, and perception of spoken language, including the following:

Thus, we come from many different disciplines, including at least physics, speech and hearing science, experimental psychology, linguistics, electrical engineering, etc.

Please read the new proposed “Scope of Scientific Activities” of the SCTC and send any comments to sctc-scope@geoff-morrison.net (Subcommittee: Geoff Morrison, Tessa Bent, Brad Story, and Ben Munson).

Support for Students

Rachel Gilbert is the SCTC student representative.  Some specific information relevant to students include:

Student Paper Award. The best paper in a Speech Communication session of the Society that is authored primarily by a student receives the Dennis Klatt Award (and a couple hundred dollars).

Student Travel Awards. Travel support for students to attend Society meetings. Applications must be submitted well before the meeting.

Student Receptions. At Society meetings a reception is held for students that offers an opportunity to meet invited senior members. For details see announcements for specific meetings of the Society.

The Raymond T. Stetson Scholarship in Phonetics and Speech Production
More information and an application form are available at the ASA Fellowships page.

Speech Communication Technical Committee

Concerned with the study of the production, transmission, and perception of speech, including the following:
-Speech production: physiology, mechanics, and acoustics of speech and voice production; models of speech production; first-language and second-language speech production
-Acoustic phonetics, including segmental and suprasegmental aspects of speech
-Speech perception: physiological and psychological aspects of speech perception; voice quality perception; models of speech perception; first-language, cross-language, and second-language speech perception
-Speech acquisition: acquisition of speech production and perception; first-language and second-language speech acquisition; models of speech acquisition
-Speech and hearing disorders: effects of speech production disorders on the articulation, acoustics, and perception of speech; effects of hearing impairment on speech perception and production; effects of aided hearing or speech (e.g., hearing aids, cochlear implants, electrolarynx) on speech perception and production
-Neuroscience of speech production and perception
-Speech intelligibility: perception and intelligibility of accented, disordered, and synthetic speech, and of speech degraded by noise or transmission channel; production and perception of speech in acoustically adverse environments
-Communicative aspects of singing: production and perception of phonetic or emotional content in song
-Speaker classification and speaker identity: articulatory, acoustic, and perceptual properties of speech linked to a speaker’s sex, gender, age, and emotional state; sociophonetics; speaker, language, and dialect recognition by humans and machines; forensic voice comparison
-Audiovisual and other multimodal speech perception
-Speech processing and speech technology: signal processing of speech; speech synthesis; automatic speech recognition
