最簡單的跟讀，不需要技術的，就是象美風愚公那樣，

1. start audacity recording

2. start origininal, play one sentence, then stop.

3. read after it.

4. start the original again.and repeat 2, and 3 for each sentence.

To mix your reading with the original, you can do following:

1) open your own reading in audacity

2) import the original

3) add 2-3 second silence time between two sensences in each recording in order to avoid overlapping of the two voices

4) export the file as mp3
