- Acquire voice samples making the five vowel sounds
- Compute the cepstrum with different methods
- Lifter the cepstrum domain signals
- Try to synthesize back the voiced signals in the following way:
Status
As of the completion of the project, it will probably be modified in case of more research in the field, but in any case it will not be maintained. It may hold inaccuracies and could be implemented in more efficient ways regarding speed and recources management.
Code
MATLAB R2018a version. Using a different version, you may need to customize some commands.
