[hts-users:00729] Mel-lsp coefficients for synthesis

Title: Mel-lsp coefficients for synthesis

Hi. I am trying to create a speech synthesis system using mel-lsp coeffcients. In the mail archives (5/21/2007) it states that mel-lsp coefficients can be computed as follows

x2x +sf temp.raw | frame -p 80 -l 400 | window -n 1 -l 400 -L 512 | \
mgcep -m 24 -a 0.42 -g -1 -l 512 -o 4 | lpc2lsp -m 0.42 -s 16 -n 512 > temp.mlsp

I wanted to check if the option -m 0.42 a typo (is it supposed to be -m 24?). Also, given the file temp.pitch, what SPTK command(s) would I use to perform synthesis from temp.mlsp?

excite -p 80 temp.pitch | ????

I have looked through the SPTK documentation, but I have not been able to figure out the correct command. Thank you very much for any help you can provide.

Thanks,
Brian Ore
