Undergraduate Graduation Project on Voice Recognition Car

For my undergraduate graduation project, I am developing a voice recognition car system. Currently, I'm seeking feedback and suggestions to further improve my design. I'm particularly interested in the application of speech recognition technology and aim to conduct in-depth research and exploration through this project. The system implementation involves several key components: audio signal processing using Python libraries like Librosa for feature extraction (MFCC coefficients), implementing speech-to-text conversion through APIs like Google Speech Recognition or CMU Sphinx, and developing motor control algorithms using microcontroller platforms like Arduino or Raspberry Pi. If you have any ideas or suggestions regarding voice-controlled car design - whether about noise filtering algorithms, command processing optimization, or motor control precision - please don't hesitate to share them with me. I hope to leverage your valuable insights to make my design more comprehensive and outstanding. Thank you very much for your assistance!
