I have a audio-visual educational content. Recently the voice-over artist whose voice was used for this content, left my company. Currently I have the need to change a few sentences in the entire audio file. Since I don't have the original artist with me.. I am in a fix. I want to avoid re-recording the entire content in a new voice.... that will mean match the new voice to the video content etc. Is there a way to record those couple of sentences and a few words by another voice over artist and then match her voice (as closely as possible) with the original voice? Which softwares can help us solve my issue and how? Currently I am comfortable with audacity for audio editing.
Your inputs will save me a lot of efforts!
