To accomplish this, we are working on a masking protocol to block participants=E2=80=99 ability to hear themselves speak and prevent them f= rom utilizing their external channel. Currently, we plan to use either White or Pink noise at an individually determined dB level presented through active noise cancelling headphones to both mask/eliminate the participant=E2=80=99s speech in a naming task. One concern we have is whether or not this sort of procedure will address information a speaker receives from bone conduction. In particular we have two questions: 1. Assuming the air channel is successfully masked, how much acoustic information can individual gather about a lexical item from bone conduction? In short, we=E2=80=99re trying to figure out how much phonol= ogical information someone can gather from this type of information. 2. On the topic of practical implementation: In masking air conducted speech have we effectively masked bone conducted speech as well, or does blocking out information from bone conduction require a unique approach? Any information or recommendations of references is greatly appreciated!
