I am doing a dissertation on Speech Enhancement using LSTM Recurrent neural netowrks.
A large portion of this is background writing on the characteristics of speech and speech enhancement. I will take care of the the artificial intelligence bit, I just want the speech processing and other background bits taken care of.

below is a outline of what i need:

1. Charactistics of speech
– how speech is created (doesnt need to be incredibly detailed)
– charactistics of a speech signal
– how we percieve speech

2. speech enhancement
– cocktail party problem
– speech enhancement algorithms (why some are good and bad)
