Audio-visual speech perception without speech cues
A series of experiments was conducted in which listeners were presented with audio-visual sentences in a transcription task. The visual components of the stimuli consisted of a male talker’s face. The acoustic components consisted of : (1) natural speech (2) envelope-shaped noise which preserved the duration and amplitude of the original speech waveform and (3) various types of sinewave speech ...
متن کاملSpeech perception without traditional speech cues.
A three-tone sinusoidal replica of a naturally produced utterance was identified by listeners, despite the readily apparent unnatural speech quality of the signal. The time-varying properties of these highly artificial acoustic signals are apparently sufficient to support perception of the linguistic message in the absence of traditional acoustic cues for phonetic segments.
متن کاملPhonological abstraction without phonemes in speech perception.
Recent evidence shows that listeners use abstract prelexical units in speech perception. Using the phenomenon of lexical retuning in speech processing, we ask whether those units are necessarily phonemic. Dutch listeners were exposed to a Dutch speaker producing ambiguous phones between the Dutch syllable-final allophones approximant [r] and dark [l]. These ambiguous phones replaced either fina...
متن کاملCategorical perception of speech without stimulus repetition
We explored the perception of phonetic continua generated with an automated auditory morphing technique in three perceptual experiments. The use of large sets of stimuli allowed an assessment of the impact of single vs. paired presentation without the massed stimulus repetition typical of categorical perception experiments. A third experiment shows that such massed repetition alters the degree ...
متن کاملSpeech Perception in Children with Cochlear Implants
Cochlear implants provide access to the speech signal in children with hearing loss that often cannot benefit from acoustic hearing aids. However, despite the numerous positive results in pediatric cochlear implantation, published data still indicated a wide range of performance among implant recipients. Hence, a need to study the possible variables that can affect performance, could account fo...
