Hi,


Sorry for having missed your report for so long.

This now no longer works under Jessie.


Indeed, text2wave now uses fseek, which can't work with pipes.

I have forwarded the report to upstream, but I'm afraid it'll be
difficult for them to work back to avoid using fseek. It probably means
you will have to use a temporary file.


No worries and thanks for getting back to me.

I've been using a temporary file thus:

-
TMP=`mktemp`
echo "$string" | text2wave > $TMP
aplay -q $TMP
rm $TMP
-

...and if that's the intended behaviour then it'd be nice to get an error 
when it gets a pipe rather than just nothing. Better still would be to 
change the interface to only deal with named files and not output to stdout 
at all.






Regards,
@ndy

Package: festival
Version: 1:2.1~release-8
Severity: important

Dear Maintainer,

I have been using text2wave in a script under Wheezy thus:

-
echo "$string" | text2wave |aplay -q
-

This now no longer works under Jessie.


text2wave receives a SIGPIPE and no audio is heard:

-
$ echo "hello" |text2wave | aplay
Playing WAVE 'stdin' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono

0:0,141,0
$

If you run the following two commands, the file generated by each is different:

-
$ echo "hello" |text2wave > /tmp/x0.wav
$ echo "hello" |text2wave | cat > /tmp/x1.wav
-

-
$ diff /tmp/x0.wav /tmp/x1.wav
Binary files /tmp/x0.wav and /tmp/x1.wav differ
-

-
$ diff /tmp/x0.wav /tmp/x1.wav  -a

���RIFF �>}datan
\ No newline at end of file

x0.wav works (audio is heard):

-
$ aplay /tmp/x0.wav
Playing WAVE '/tmp/x0.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono
-

x1.wav does not work (no audio is heard, but no error is reported):

-
$ aplay /tmp/x1.wav
Playing WAVE '/tmp/x1.wav' : Signed 16 bit Little Endian, Rate 16000 Hz, Mono
-


Thanks for anything you can do to get me working again!
