acoustic signal
the pattern of frequencies and intensities of the sound stimulus
acoustic stimulus
the pattern of frequencies and intensities of the sound stimulus
aphasia
difficulties in speaking or understanding speech due to brain damage
articulator
structure involved in speech production, such as the tongue, lips, teeth, jaw and soft palate.
audiovisual speech perception
a perception of speech that is affected by both auditory and visual stimulation, as when a person sees a tape of someone saying /ga/ with the sound /ba/ substituted and perceives /da/.
broca's aphasia
language problems, caused by damage to broca's area in the frontal lobe, characterized by labored and stilted speech and short sentences.
categorical perception
in speech perception, perceiving one sound at short voice onset times and another sound at longer voice onset times and another sound at longer voice onset times. the listener perceives only two categories across the whole range of voice onset times.
coarticulation
the overlapping articulation that occurs when different phonemes follow one another in speech.
formant
horizontal band of energy in the speech spectogram associated with vowels
formant transitions
in the speech stimulus, the rapid shift in frequency that precedes a formant
indexical characteristics
characteristics of the speech stimulus that indicates information about a speaker such as the speaker's age, gender, and emotional state.
invariant acoustic cue
in speech perception, a feature of an auditory signal that remains constant even in different contexts
mcgurk effect
a perception of speech that is affected by both auditory and visual stimulation, as when a person sees a tape of someone saying /ga/ with the sound /ba/ substituted and perceives /da/.
motor theory of speech perception
a theory that proposes a close link between how speech is perceived and how it is produced. the idea behind this theory is that when we hear a particular speech sound, this activates the motor mechanisms that are responsible for producing that sound and it is the activation of these motor mechanisms that enable us to perceive sound
multimodal
the involvement of a number of different senses in determining perception.
phoneme
the shortest segment of speech that, if changed would change the meaning of a word
phonemic restoration effect
an effect that occurs in speech perception when listeners perceive a phoneme in a word even though the acoustic signal of that phoneme is obscured by another sound, such as white noise or a cough.
phonetic boundary
the voice onset time when perception changes from one speech category to another in a categorical perception experiment
running spectral display
a way of representing the speech stimulus in which a number of short-term spectra are arranged to show how the frequencies in the speech stimulus change as times progresses.
segmentation problem
the problem of perceptually segmenting the continuous speech stimulus into individual words
shadowing
listeners' repetition aloud of what they hear as they are hearing it
short-term spectrum
a plot that indicates the frequencies in a sound stimulus during a short period, usually at the beginning of the stimulus.
speech spectrogram
indicates the pattern of frequencies and intensities over time that make up the acoustic signal
voice onset time (VOT)
in speech production, the time delay between the beginning of a sound and the beginning of the vibration of the vocal chords
wernicke's aphasia
an inability to comprehend words or arrange sounds into coherent speech, caused by damage to wernicke's area.
wernicke's area
an area in the temporal lobe involved in speech perception. damage to this area causes wernicke's aphasia, which is characterized by a difficulty in understanding speech
word deafness
occurs in the most extreme form of wernicke's aphasia, when a person cannot recognize words, even though the ability to hear pure tones remains intact.
