  4. 4. Our Method (steps) Word Segmentation: ស ស ស ស ស ស ស ស ស ស ស ស→ សស ស សស ស ស សស ស , ស ស ស ស ស ស ស សស សស សស ស Text Normalization: →ស ស ស ស ស ស ,ស ស ស ស ស ស ស ស ស ស ស ស ស ស ស Text To Sound Conversion: ស ស ស ស→ kakthen Syllabification: sa:la: → sa: . la: Stress Assignment: sa: . la: → sə . la: Sound Change: ស ស ស សcak → caʔ Intonation Diphone Database Integration 4 Applications Development (mail reader, doc reader, ...)
  5. 5. New Statistical System Speech corpus ~450 sentences (~30 minutes) Automatic labeling  EHMM labeler  Sphinx Statistical parameter synthesis More natural, but buzzy Unit selection Units of variable size (smallest unit is phone) More natural, but bad quality at join points 5
