[UniMRCP] umc.exe & Loquendo - 006 recognizer-error

[mr_b]

Hello,

I am having some problems with testing umc.exe client with Loquendo
Speech Suite (MRCPv2 Server). I use the same xml config setting as in
my other asterisk client (which works) so I think the problem may be
somewhere in umcscenario.xml, grammar.xml or audio file. I have only
Polish license for Loquendo ASR so testing with default (English)
files is impossible for me but I tried to make as few modifications as
possible.

The problem is i get 006 error in lots of different situations with an
error reason which is false in my opinion.

Completion-Cause: 006 recognizer-error
Completion-Reason: Recognizer Error: "API lasrxRecog in module
Loquendo ASR 7.8.
2.0 returned with code -103: Audio samples timeout expired. No audio
samples hav
e been delivered "

The only setup that has (sort of) worked for me was with audio
one-8kHz.pcm and this grammar file:

<?xml version="1.0" encoding="UTF-8"?>
<grammar xmlns="http://www.w3.org/2001/06/grammar" xml:lang="pl-pl"
version="1.0" mode="voice" root="digit">
<rule id="digit">
<one-of>
<item>jeden</item>
<item>dwa</item>
<item>trzy</item>
<item>cztery</item>
</one-of>
</rule>
</grammar>

i get 'trzy' (~0.5 conf) in response even though it is not even close
to what would english 'one' be using Polish phonetic transcription.
Maybe it has something to do with analyzing 8kHz audio as 16kHz or the
other way around? I tried changing codec values in config files but
nothing has worked for me.

The weird thing is if i remove or replace 'trzy' in grammar with any
other correct word i get 006 error. Below I attach both scenarios. I
also tried making different .pcm/.wav files, 8 and 16 kHz to use
Polish language but i get 006 error with the same cause.

Hi, 006 is a recognizer error. check this:

http://tools.ietf.org/html/draft-ietf-speechsc-mrcpv2-22#section-9.4.11

I'm sorry I didn't read all of your emai. I'm trying to solve a bad confidence with pocketSphinx ASR :-)

[mr_b]

Thank you for the link but unfortunately that is what I already know.
I'm pretty sure the problem is on the client side because the same
server is fully functional with other unimrcp client (asterisk
connector bridge). I have basically the same config but it still isn't
working.

If someone could send me some audio, grammar and all the xml files
used by umc.exe that has worked for them with Loquendo speech server I
would be grateful. I am aware that Loquendo is probably less popular
than Nuance and other servers (at least in this group) so I will take
anything else that would be useful. As for the xml config files I
think umcscenarios.xml and one of the client-profile xmls would be
sufficient.

All I try to do is make unimrcp run with anything properly, even basic
grammar so that I can change some things in umc code. What I am tryind
to achieve in the end is the easiest scenario possible: send recorded
audio with preconfigured grammar and receive results. The only
parameter is file name and I want the application to be able to run
multiple requests at the same time so either concurrently in one
instance or multiple instances of app at the same time. So if I am
heading the wrong way than please do tell me. Maybe its easier to set
up unimrcpclient.exe? I really have no preferences but this one gives
me the same results so far.

[mr_b]

If anyone is having a similar problem try adding even more silence
after the spoken phrase (at least 3 seconds). The amount in one.pcm
may be insufficient and the grammar has nothing to do with it, its all
about the audio file. The reason for why changing the grammar affected
the result probably is that a certain element can be recognized
'faster' so that a shorter amount of silence is OK.

What worked for me is a wav file instead of pcm (with 16bit sample
rate and 8kHz frequency). I also had 002 no-input-timeout error before
which was caused by changing

<termination enable="1">
<capabilities>
<codec name="LPCM" rates="8000 16000"/>
</capabilities>
</termination>

to

<termination enable="1">
<capabilities>
<codec name="PCMU" rates="8000 16000"/>
</capabilities>
</termination>

in recog scenario. The good one (2nd) is default.
