I am a cognitive psychologist who is interested in human speech and language perception.
Perceiving spoken language seems to be simple. After all, we require little conscious effort to derive meaning from the auditory input. Except of course when the sound is of poor quality, or when we do not know the words or the language, or when we are babies, or when our hearing is impaired, or when our brain is damaged.
Speech perception is thus not so simple. It depends on many factors, and we are lost without context.
My research focuses on how and when different types of context - such as our internal dictionary, or seeing the moving mouth of the person who is talking to us - can drive adjustments in the way we perceive speech sounds.
