Canonical Syllable(also: Canonical Babbling, Well-Formed Syllable)

A canonical syllable is a well-formed syllable in infant babbling that consists of a consonant-like closure (closant) produced by an oral cavity constriction followed by a vowel-like opening (vocant). Canonical syllables typically appear between 5 and 10 months of age in the…

Computer Feedback System(also: CFS, Computerized Feedback System)

A technology system that detects a user's behavior — such as vocalizations, movements, or physiological signals — and provides immediate audio, visual, or haptic responses mapped to that behavior. In speech and communication interventions, computer feedback systems translate…

Computer-Assisted Language Learning(also: CALL, Computer-Aided Language Learning)

Computer-Assisted Language Learning (CALL) refers to the use of computers and digital technology to support language education and pronunciation training. CALL systems often incorporate automatic speech recognition to provide feedback on learner pronunciation, detect…

Computer-Based Speech Training(also: CBST, Computer-Aided Speech Training, CAST)

Computer-based speech training (CBST) refers to software systems designed to help individuals improve their speech production through automated exercises, feedback, and practice. These systems typically present target words or utterances, capture the user's speech through a…

Concatenated Speech Synthesis(also: Concatenative Synthesis, Unit Selection Synthesis)

A method of producing synthetic speech by connecting pre-recorded segments of human speech, typically diphones (transitions between phonemes) or demi-syllables, to form complete words and sentences. Concatenated speech synthesis produces more natural-sounding output than older…

Concatenative Synthesis(also: Unit Selection Synthesis)

A text-to-speech method that generates synthetic speech by concatenating (joining together) pre-recorded segments of human speech. These segments, called units, may be phonemes, diphones, syllables, or words. The system selects and joins appropriate units from a large database…

Connected Speech Recognition(also: Continuous Speech Recognition)

A form of automatic speech recognition in which users speak words naturally, with normal coarticulation and minimal pauses, rather than pausing between each word as required by older 'discrete' or 'isolated-word' recognisers. Connected-speech recognition was a significant…
