- Hi!
-
- Guide to make a workable Klatt Synthesizer
- ------------------------------------------
-
- 1. Subscribe the 3 parts of the Klatt synthesizer from
- nn. (The set sent by "CTI acct" is ok!)
- 2. Cut off the header for the three files. You can do
- this by using a text editor (like vi). For each file,
- you can identify the header part and data part
- easily because the data part is a long, continous and
- unreadable string of characters.
-
- Note: The first line of the data part of PART ONE starts
- like this:
-
- begin 777 klatt.tar.Z
- [Subsequent lines]
-
- 3. Merge the 3 files into a single text file using a text
- editor. Put PART ONE in the editor first, then insert
- PART TWO at the end of PART ONE (leaving no spaces)
- Then insert PART THREE at the end of PART TWO.
-
- 4. Let us called the merged file "klatt.tar.Z". Now we are
- ready to extract the source codes.
-
- A) Use uudecode to get a compressed tar file FIRST:
-
- % uudecode klatt.tar.Z
-
- This will produce a compressed tar file klatt.tar.Z
-
- B) Then use uncompress to get a "plain" tar file
-
- % uncompress klatt.tar.Z
-
- This will produce a tar file called klatt.tar
-
- C) Use tar to extract all sources files
-
- % tar -xvf klatt.tar
-
- This time the source files will be produced. Wow!
-
- Notice: The source codes will be produced on a
- subdirectory called "klatt" under your
- working directory.
-
- D) Use "make" to build all executables
-
- % cd klatt
- % make
-
- CAUTION: Unless you are VERY LUCKY, you must modify the
- source codes before you can get a WORKABLE
- version.
-
-
- SOFTWARE:
-
- There are 4 executables:
-
- klatt: Klatt synthesizer
-
- A menu-driven (though very "UGLY") klatt syn which can
- accept a parameter files are produce sound from it. Ideal
- for experts who wish to generate parameter file by his own
- and fine-tuning parameters of the synthesizers.
-
- gen: Phoneme-to-speech
-
- Users can produce speech from phonemes input by user, ideal
- for casual users. It calls uklatt to produce sound.
-
- uklatt: Parameter-file to speech converter.
- sklatt: Similar to uklatt (?)
-
-
- NECESSARY MODIFICATION:
-
- hplay.c: If you examine the code you'll find a "dummy" printf
- statement, you should use hplay.old instead.
-
- libaudio.h: These are a set of SUN audio header files. Make sure
- (and others) that you've selected the right include file path in your
- makefile
-
- libaudio.a: You must supply this library in the linking process,
- otherwise there will be linking errors.
-
- The speech waveform is stored in an array called "iwave". This
- array is a short integer array (so, the resolution is 16-bits).
- These data are compressed by mu-law and stored in another array
- called "plabuf". Speech sampling freq=8000 Hz. If you want to
- extract the waveform, you can "hooked" into the routine
- "hplay" in hplay.old.
