Explore MATLAB source code curated for "语音信号分析" with clean implementations, documentation, and examples.
MATLAB source code for speech signal analysis including harmonic analysis, intensity analysis, and source analysis. This software package comprises a collection of MATLAB routines designed for comprehensive prosodic analysis of speech signals, featuring fundamental frequency (F0) estimation, harmonic structure examination, loudness measurement, and voice-source characterization through specialized signal processing algorithms.
Speech signal analysis, processing, and design. The MATLAB-based voice changer operates by modifying the input sound's frequency to alter timbre and pitch, creating perceptually different output. This dual modulation of timbre and pitch transforms vocal characteristics. User-generated voice inputs leverage resampling techniques for formant frequency shifting, implementing key DSP algorithms including frequency scaling and spectral envelope modification through functions like resample(), pitch shifting, and formant correction.
