Audio and speech digital processing

Context:
    Audio and speech digital processing (4th grade)

Technologies:
    Audio processing, Matlab, C

Description:
    This project consisted in applying audio processing techniques to model and modify speech audio.
    There are two main parts on this project. The first part consists in an analysis of the pitch marks of a speech audio, a split of the harmonic and stochastic parts and a reconstruction of the audio. The second part is again an analysis and split but this time to modify the Time and Pitch of the audio with established factors.
    This project allowed me to understand better the digital processing of the speech and how to modify it.
