DEC-TALK USB and speech dispatcher

[Klarich , Terry J .]

Hello all:

Obviously, I am new to this list.  My name is Terry Klarich.  I work as a 
systems analyst for a natural gas company in Oklahoma U.S.

I am presently experimenting with the DEC-Talk USB under Linux.  I contacted 
the manufacture and did receive the info to build a driver.  I can send speech 
and commands to the DEC-Talk.  I can talk to the DEC-Talk either using the 
libusb libraries or directly using a kernel driver.  I am still trying to get 
index marks working.  I hope to work more with the manufacturer to get index 
marks working.

I have written the beginnings of a speech dispatcher module.  I didn't use the 
sample module code discussed in the speech dispatcher documentation.  Rather, I 
wrote it from scratch.

I am running into a problem.  I'm hoping someone can assist.  When starting 
speech dispatcher, it hangs when sending the "INIT\n" command to the sd_dtusb 
module.  Here is the log:

[root at oke11528 speech-dispatcher]# cat speech*log

[root at oke11528 speech-dispatcher]#

My sd_dtusb module is also hanging.  I don't get any log information.  Here is 
what it looks like when I run the module by hand:

[root at oke11528 tmp]# /usr/lib64/speech*mod*/sd_dtusb /dev/null
INIT
299-DTUSB INITIALIZED
200 dtusb version 0.1, ready
AUDIO
205 SEND SETTINGS
.
208 SYNTHESIZER INITIALIZED
QUIT\
300 SYNTAX ERROR
QUIT
202 TERMINATING
[root at oke11528 tmp]#

And the log from the above commands:
[root at oke11528 tmp]# cat /tmp/dtusb.log
starting up
starting up
Waiting for INIT
Initialized
200 dtusb version 0.1, ready
205 SEND SETTINGS
208 SYNTHESIZER INITIALIZED
init thread (output)
state = 1
300 SYNTAX ERROR
202 TERMINATING
[root at oke11528 tmp]#

Again, I think sd_dtusb is hanging because nothing is printed in the log.  The 
first debug message is printed as the first line in main().  I didn't do 
anything special with stdin or stdout.  Looking in the source for 
speech-dispatcher, it looks like a popen is used to start sd_dtusb.

Any help would be much appreciated.  I hope I can get this working.  I signed 
up for the list; but, don't think my access has been granted.  And, I don't 
know how busy this list is.

Many THANKS!
Terry
