Speech for wedding

My wife is in a care home and is unlikely to be able to make the weddings of our children. I wrote a very short script (see attached) and I have helped my wife recorded her saying the script. The audio is over 5 or 6 files (around 4 seconds to 20 seconds each) as she is not able to say the full script in one go.

What I am after is for the words she had spoken over these audio files to be captured into one continuous audio file, the audio enhanced as much as possible so that we end up with one continuous audio file that we can play at their weddings. There will be two audio recordings, one for each of our children - the same audio for each apart from the introduction.
