I set up a proxy and changed Services -> lexicon in the wikispeech_server config file to localhost/lexserver, it works. And the links work as well, with the lexserver prefix.
Not sure if it will work with the setup on wikilabs - but with a bit of luck it will.

Need to check this..
In my setup using the -r lexserver switch breaks the links in http://localhost:8787/lexicon/, but wikispeech_server works normally. But of course there is no proxy in use. I'll set that up and see if I get the same error as in the log above.

There are now test examples in templates/test.html, of ssml with ipa, and of the new "ipa" input type.
To check which ipa symbols are allowed for a certain language: http://localhost:8771/symbolset/content/sv-se_ws-sampa (the url to the symbolset mapper)

Test version available in git - allows ipa in ssml input

Need to update to latest version of mishkal

Changed to use
logging.handlers.SysLogHandler(address = '/dev/log')
instead of
logging.StreamHandler()

Added a setting to wikispeech-server/default.conf:
#logger defaults to stderr, uncomment here if you want something else
#logger: syslog
#logger: /tmp/wikispeech.log

There is now an endpoint /default_voices that returns json similar to this:

Output json now contains timing in milliseconds instead of seconds

audio_url is no longer returned.
Tmp dir is cleared after each call.

Yes, wrong format was returned. Now fixed in git.

Json item "voice", with items adapter, config_file, engine, language, name has been added.

Partly done - a call to the wikispeech server, eg. http://localhost:10000/?lang=sv&input=sju%20sj%C3%B6sjuka%20sj%C3%B6m%C3%A4n. now also contains audio_data, a base64 encoded string. The audio_url still there as well, will remove that later. For testing you can also try adding the parameter output_type=html, eg. http://localhost:10000/?lang=sv&output_type=html&input=sju%20sj%C3%B6sjuka%20sj%C3%B6m%C3%A4n.
This will return very simple html with an audio element containing the base64 string as source.

I can't reproduce this - here's what I get when starting MaryTTS without a running mishkal server:

The reason for the "spike" is still unknown. But the low volume after is caused by the "Amplitude Normaliser" in Marytts.
