Hello, I have a problem when using the HTS CMU demo. The program runs correctly at the beginning, but then I have an error : "can't open file gv-lf0.pdf". The file is in the directory /gv, but it seems to be empty. I have no problem with the file gv-mgc.pdf. Thank you for your help. Mathias. Internship, School of Electronics, SpeechLab, DCU.
