        - This project is based on the paper "A Simple Digital Model of the Diode-Based Ring-Modulator," which can be found at http://recherche.ircam.fr/pub/dafx11/Papers/66_e.pdf.

        - This project builds upon the excellent work of [Neil Lakin/robot_voice](https://github.com/nrlakin/robot_voice) on his **robot_voice** project. Please follow my GitHub repository - [Voice-Human2Robot](https://github.com/danhtran8mind/voice-human2robot) to get more features.
        
        - Here is decription of parameters.
        
        | Parameter | Default Value | Description |
        |---|---|---|
        | `VB` | 0.2 |  Controls the volume of the **bright** part of the speech. Higher values result in a shorter voice that might be difficult to hear clearly. |
        | `VL` | 0.4 |  Controls the volume of the **low** part of the speech. Higher values result in a shorter voice that might be difficult to hear clearly. |
        | `H` | 4 |  Controls the slope of the linear section of the diode model's response, which kicks in after the voltage exceeds `VL`. |
        | `LOOKUP_SAMPLES` | 1024 |  Determines the size of the **lookup table** used for sound synthesis. Lower values can introduce noise. |
        | `MOD_F` | 50 | Controls the **modulation frequency**, which influences the "robotic" effect. Higher values produce a more robotic sound. |
        
        **NOTE:** `VB` and `VL` are NOT the same value.
