Thesis advisor: Sergio Alvarez / Musical notes are acoustic stimuli with specific properties that trigger a psychological perception of pitch. Pitch is directly associated with the fundamental frequency of a sound wave, which is typically the lowest frequency of a periodic waveform. Shifting the perceived pitch of a sound wave is most easily done by changing the playback speed, but this method warps some of the characteristics and changes the time scale. This thesis aims to accurately shift the pitch of musical notes while preserving its other characteristics, and it implements this in real time on an Android device. There are various methods of detecting and shifting pitch, but in the interests of simplicity, accuracy, and speed, a three step process is used. First, the fundamental pitch of a stable periodic section of the signal is found using the Yin pitch detection algorithm. Secondly, pitch marks that represent the local peak of energy are found, each spaced out by roughly one period (inverse of the fundamental frequency). Lastly, these marks are used in the Pitch Synchronous Overlap and Add (PSOLA) algorithm to generate a new signal with the desired fundamental frequency and similar acoustical characteristics to the original signal. / Thesis (BS) — Boston College, 2013. / Submitted to: Boston College.

The Japanese language is known for its various styles of speech, conditioned by factors such as social status, formality, and gender. When a speaker switches between the speech styles within the same talk targeted at the same recipient, such a phenomenon is called speech style shifting (hereafter SS). This study explores the frequency and the functions of SS through examining two types of conversations (Japanese native/native and native/non-native conversations) quantitatively and qualitatively in order to gain further understanding of the phenomenon. The results shows that all natives employed SS, and they produce SS approximately twice as frequently when the talk is targeted to non-natives than to natives. They also show that certain functions of SS are employed as foreigner talk (Ellis 2008) aimed at assisting non-natives. The study reveals the complexity of SS and underscores the necessity of closely observing various types of discourse to advance understanding of SS. / Japanese Language and Linguistics
