The voice communication switch with peak power analysis on smart phone systems
This study is a numerical analysis with the peak power of sound channel under its numerical range of the region as the signal of voice communication can automatically start Bluetooth on iOS smart phone systems. Besides, the voice communication link using Bluetooth protocol. At the same time, the entire system is implemented in the intelligent mobile devices. In this study, the intelligent mobile devices use microphone and mobile device operating system's built-in audio API to collect the data from the peak power channel of voice. The collected data is trended and noise reduction processing, so that it is easy to be used to identify trends in data. From the data analysis of the experimental results show that the significant differences in peak power generated by the people blowing sound and spoken voice data. Then, it can use the peak power value as a voice call to control the start signal of Bluetooth. The user can automatically open the call process by the people blowing sound without any manually processes. Besides, the peak power identification model is also a universal model, it can be easily extended into other operating systems on smart phone.
