Speech Display Software?

Hello folks,

I have recently fitted a profoundly deaf young man (28) who has been 
deaf since birth with an AVR FT 40 Mk2 Transposition instrument to use 
in conjunction with his Phonak PPC P2 Postaural instruments via mic 
off shoes and Audio input.

Initial results are very encouraging. He has a left corner audiogram with no 
measurable response to pure tone above 2kHz. 

Using a high frequency transposition coefficient (Zc) of 
around 2.5 he was able to detect high frequency speech sounds with ease 
and can differentiate 'SH' from 'S'

He is very keen to improve his speech production and 
whilst the Transposer will ultimately help with this 
he has asked if there is any software available 
for use with the PC which will enable him to monitor pitch and 
amplitude in real time. 

I know there were a number of commercial products available a few years ago 
- Visispeech?, however I am sure that with the processing power available 
now that there must be a hard/software package available that would 

I would be grateful for any advice / suggestions.
