  1. Topic: Tuning the Labels Kishore Prahallad Email: skishore@cs.cmu.edu Carnegie Mellon University & International Institute of Information Technology Hyderabad Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  2. Objective of this Lecture • To tune the labels (phone boundaries) to get better quality output Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  3. Better Labels • Research: • Automatic segmentation models such as HMMs or neural networks could be tuned to obtain better labels. • Practical: • Use existing state-of-art speech segmentation algorithm • Manually verify and correct the misaligned labels • For small databases, manual correction is more apt. • Emulabel is the tool best suited for this purpose. Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  4. Install Emulabel Step 1: untar the package (see course web site for emulabel package) $tar xvfz EMULABEL.tar.gz $ cd EMULABEL $ls (type ls to see the contents) Step 2: untar the emu-linux $tar xvfz emu-linux-1.4.2.tar.gz $cd emulabel Step 3: Login as root to install Emulabel $su .... #./doinstall.sh (install emulabel) Step 4: Go back to the EMULABEL directory #cd .. Step 5: Install TCL/TK versions.... #rpm -i tcl-8.0.5-35.i386.rpm --force #rpm -i tk-8.0.5-35.i386.rpm --force #rpm -i tclx-8.0.5-35.i386.rpm --force Step 6: Check to See, whether it runs: #exit (come out of the root login) Step 7: Go to voice directory $emulabel etc/emu_lab (this command should invoke GUI of emulabel) Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  5. Emulabel invoked… Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  6. Step 1 Press return Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  7. Step 2 List of wave files appear here. Select one to label Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  8. Step 3 Wave files and the red-labels appear Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  9. Step 3 Move these red markers to move the boundaries Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  10. Step 3 Listen to this red-marked region by right-click the mouse Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  11. Manual Labels • Save the manual corrected labels • Labels are stored in lab/ directory. Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)

  12. Evaluation • Compare the voice samples synthesized • before labeling Vs after labeling Speech Technology - Kishore Prahallad (skishore@cs.cmu.edu)
