Voice Morphing
INTRODUCTION
Voice morphing is a technique for modifying a (source) speaker's speech to different (target) speaker.
Voice morphing means the transition of one speech signal into another.
EXAMPLE
Online games lately provide a function that players can join them as one of the limited number of prepared characters. Many of such games use a voicing function with which users talk each other using the character’s voice instead of their own voices.
Morphing process: A Comprehensive Analysis
The main process can be categorized as follows
1) Representation conversion
2) Cepstral analysis
3) Morphing
4) Signal re-estimation
Morphing process : MORPHING
To create an effective morph, it is necessary to match one or more of these properties of each signal to those of the other signal in some way.
The match path shows the amount of movement required in order aligning corresponding features in time
Research Goals
To develop algorithms which can morph speech from one speaker to another with the following properties.
High quality
Cross language voice conversion
The ability to operate with target voice training data ranging from a few seconds to tens of minutes.
APPLICATION
Entertainment
In Computer Gaming
In Film Industry
