Speech Perception Worksheet
Complete the following table.
| Components | Description/Function |
| Acoustic signal | Noises produced by animals responding to a specific situation or stimulus having a specific meaning. |
| Articulators | A mechanical device that is used in the dentistry with an aim to cast the upper (maxillary) and the lower (mandibular) teeth reproducing positions within the mandible in relation to the maxilla. |
| Formants | Identified as the concentration of the acoustic energy on a particular frequency within the speech wave. There exist several formats at different frequencies corresponding to a resonance within the vocal tract. |
| Sound spectrogram | Spectrogram is identified as a visual representation on the spectrum of frequencies within a sound. The sound spectrogram can be identified as a graphic representation that is being produced by a sound spectrograph with relation to the intensity, frequency, duration and the variation of time in relation to the resonance. |
| Formant transitions | The rapid change of frequency of format of a vowel immediately after or before a consonant. The transition functions to signal information based on the manner of articulation of a given consonant. |
| Phonemes | Identified as the basic unit within a language’s phonology that functions to be combined with other phonemes on the essence of creating meaningful units. |
| Categorical perception | The experience of percept invariances within the sensory phenomena that can be varied along the continuum. |
| McGurk effect | A perpetual phenomenon aiming at demonstrating the interaction between vision and hearing in speech perception. The effect illustrates the fact that what our eyes see can influence what we hear. |
| Speech segmentation | The process of defining the existing boundaries between syllables, words and phonemes within the spoken natural languages. |
| Transitional probabilities | The probability of transitioning from one state to another in a Markov process. |
| Indexical characteristics | A characteristic of the speech stimulus that functions to illustrate information about a speaker for instance the speaker gender. |
| Broca’s aphasia | A disorder that is cauterized by the incapable nature of an individual to produce language either spoken or written. |
| Wernicke’s aphasia | Type of aphasia on which an individual is incapable to understand language in either its spoken or written. |
| Dual-stream model of speech perception | Identified as a tactography evidence with two functional distinct compu6tational networks that process speech or language information. One interfaces sensory networks with conceptual-semantic systems while the pther sensory networks with motor-articulatory systems. |
| Motor theory of speech perception | Identified as the hypothesis on which People tend to perceive the spoken words through the identification of vocal tract gestures that are pronounced rather than the enhanced capability of identifying the sound patterns on which the speech generates. |
