Working:
The pitch device operates by capturing the user's voice through a built-in microphone 104 when the user speaks and sings. The microphone 104 converts the sound into audio signals, that are then processed by the signal processing module. This module uses pitch detection and tracking algorithms to analyse the audio signals, extracting the fundamental frequency that represents the user's pitch. As the pitch is detected, the vibration sensor 112 continuously monitors for any deviations from the specified pitch range. If the detected pitch goes above or below a set limit, the vibration sensor 112 sends a signal to create vibrations, providing feedback to the user to help them to adjust their pitch. The pitch information is displayed on a screen, allowing the user to see the changes in real time. Additionally, the device is customized to suit different needs by adjusting the pitch range through its calibration settings. This makes the device versatile for various uses such as singing, speech training, and language learning.
The pitch device employs autocorrelation, fast fourier transform (FFT), and ceptral analysis techniques to analyse the periodic characterstics of the audio signals, and identify the fundamental frequency, that corresponds to the user's pitch. The pitch device is designed with various features to increase its overall usability, and functionality. It includes a memory function that enables the storage of pitch measurements overtime, allowing users to track their pitch development, and analyse their vocal performance. This feature is useful for continuous improvement in singing and speech training activities. The device features a user interface that allows for the adjustment of different settings, including sensitivity, vibration feedback intensity, and calibration parameters. These settings ensure that the device is designed to meet individual user requirements. The pitch device incorporates a data communication module 116 that facilitates the transfer of pitch data to external devices and networks, supporting data sharing, further analysis, and integration with other applications. Additionally, the device includes a power management system designed to optimize energy consumption, thereby extending battery life, and making the device suitable for prolonged use in various settings. The pitch device serves as portable, precise, and user-friendly solution for real-time pitch measurement and feedback. The device's portable design, adjustable settings, and flexible features make it well-suited for a range of users, including vocal training, public speaking, and language learning.
