There are algorithms to perform voice conversion, but I doubt they are implemented in Java. A good voice conversion scripts are part of the http://festvox.org/ text-to-speech synthesis system.

Still, the result of the conversion is not very natural. The converted voice doesn't fully sound like human, it contains noises, intonation is not always natural and so on and so forth. I sincerely recommend you to consider using human voices for teaching.

You may have to resolve this in two steps:

  1. You need a Java Speech Recognition tool. I recommend using Sphinx .I've worked with it and it works (not perfect, but it works really well). Take a look at this hello world demo.
  2. You need a Text to Speech tool. I highly recommend FreeTTS. By default, there are just 3 male voices avaliable, but it's easy to import female voices. This link will guide you through this proccess. I can see that there is a female voice avaliable there:

FreeTTS also interfaces with the MBROLA synthesizer and can use MBROLA voices. There are three US English MBROLA voices available:

> 16kHz female (mbrola1) 16kHz male (mbrola2) 16kHz male (mbrola3)

I think it depends on what you want to do.

I think you can manipulate the sounds by using a synthesizer. Java does have a synthesizer class using Java MIDI. You may want to look at this.
