Video editing with text to speech I am trying to do some screen recordings and uploading them to YouTube. I have a terrible voice and frankly I cannot maintain a stream of speech meaning the the end product will end up being bad. I saw some videos online:


                
            

The uploader made use of text-to-speech (TTS) voices. Even though the voice is obviously terrible, the audio was perfectly synchronized with the video.

I am not asking for any sophisticated way of editing videos. All I want to know is a way I can easily add audio to my screen recordings. I have an old version of Camtasia and it doesn't provide a TTS engine meaning that I have to use another program, type what I want to be converted to speech, save as an audio file and import to Camtasia. The problem is that my videos are about 15 min long meaning that it will be an extremely tedious task to be using the two software simultaneously. In fact, what I'm most worried about is having to change some word and maintaining a good synchronicity between the video and audio.

So, I hope anyone with experience in creating such videos can direct me to the easiest way of doing it.

Thanks
You can do this, but why bother.  It is far faster and easier to record your dialog in multiple takes.  As long as you can naturally speak a sentence or two at a time, you can narrate your own video by carefully editing your dialog from multiple takes.  DAW tools will even play the video for you while you are dubbing over it and let you hear what happened before and after your take in order to give you context.  This is faster and will sound better than your text to speech solution.

If you still really want to do text to speech, I would recommend taking the same kind of approach.  Make clips for each of the phrases you need and then move them in to the video and place them as needed.
