Abstract:
Parallels in the production of clear speech and words under prosodic focus suggest that both may be realized in the same way: as hyper-articulated speech. To directly investigate this possibility, school-aged children and college-aged adults produced target words in a default conversational style, a clear speech style, and with prosodic focus. The results were that children and adults both produced target vowels more distinctly and with greater mouth opening in the clear speech and prosodic focus conditions than in the default condition. Whereas the temporal scope of production changes varied as a function of condition in adults' speech, there was no evidence of this in children's speech.

Interference: Path Lengths
Two special sources may be considered when they are in phase. This can be easily achieved by feeding the two sources from the same source. An example would be synchronizing the two speakers by feeding them with the same source, such as the sound waves produced by a tuning fork. This setup ensures that the two sources have the same frequency and are...
