I have been using Speech Tools, Festival and Festvox. There was no problem, so far, with my 32-bit Ubuntu 11.10 while installing Speech Tools etc.
For the past 4/5 weeks I have been trying to install Speech Tools on my 64-bit machine. I have tried: Virtual Box with 32-bit & 64-bit Ubuntu, installed Ubuntu 64-bit alongside Windows 8.
I tried with several version of gcc (4.7 down upto 4.4). Didn't succeed.
[Festival documentation says gcc-4.5.* max.]
Why I am trying it ?
-------------------------
Reason: My laptop comes with a 2GB RAM, a 32-bit machine.
I am working with a 5 hour of utterance data. Everytime, while unit clustering, it stops due to want of more memory. (One unit occurred 14000+ times.)
Probable solution:
-----------------------
1. Selective clustering. (Does anyone know how to do it?)
2. Increasing RAM size of my Laptop. (Please comment, if anybody know more about it. I am thinking of it because, as per my knowledge, Festival loads the units in RAM while clustering.)
3. I already have a 64-bit Desktop PC with 4 GB RAM. I wanted to make use of it. Thus, I tried installing there. But no success so far.
