XCALLY Motion can potentially be integrated with any ASR/TTS system based on MRCP.

In the following section you find an example of this kind of integration (Lumenvox).

LumenVox Integration

Configuring UniMRCP to work with LumenVox

Info
UniMRCP is a pre-requisite of this integration: if it is not installed yet, see on this page how to do it.

You need to configure:

The mrcp.conf file in /etc/asterisk/
The res-speech-unimrcp.conf file in /etc/asterisk/
The unimrcpclient.xml in /usr/local/unimrcp/conf/
The lumenvox.xml in /usr/local/unimrcp/conf/client-profiles/

Step 1: Configure res_unimrcp.so module by editing the mrcp.conf file

Here you can find a working mrcp.conf example (to be modified accordingly with your environment):

[general]

default-asr-profile = speech-lumenvox-mrcp1

default-tts-profile = speech-lumenvox-mrcp1

; UniMRCP logging level to appear in Asterisk logs. Options are:

log-level = DEBUG

max-connection-count = 100

offer-new-connection = 1

; rx-buffer-size = 1024

; tx-buffer-size = 1024

; request-timeout = 60

[speech-lumenvox-mrcp1]

; +++ MRCP settings +++

version = 1

;

; +++ RTSP +++

; === RSTP settings ===

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; Set this to the LumenVox Media Server's IP:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

server-ip = X.X.X.X

server-port = 554

; force-destination = 1

resource-location = media

speechsynth = speechsynthesizer

speechrecog = speechrecognizer

;

; +++ RTP +++

; === RTP factory ===

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

; Set this to the XCALLY Motion machine's IP:

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;

rtp-ip = X.X.X.X

; rtp-ext-ip = auto

rtp-port-min = 4000

rtp-port-max = 5000

; === RTP settings ===

; --- Jitter buffer settings ---res-speech-unimrcp.conf

playout-delay = 50

; min-playout-delay = 20

max-playout-delay = 200

; --- RTP settings ---

ptime = 20

codecs = PCMU PCMA L16/96/8000 telephone-event/101/8000

; --- RTCP settings ---

rtcp = 1

rtcp-bye = 2

rtcp-tx-interval = 5000

rtcp-rx-resolution = 1000

1) Set the server-ipdirective pointing to the Lumenvox Media Server IP.

2) Set the server-port directive tothe Lumenvox Media Server port.

3) Set the rtp-ipdirective pointingto the XCALLY Motion IP.

Step2: Configure res_speech_unimrcp.so modules by editing the res-speech-unimrcp.conf file

Here you can find a working res-speech-unimrcp.conf example:

[general]

; UniMRCP named profile. Options are:

;unimrcp-profile = uni2 ; UniMRCP MRCPv2 Server

;unimrcp-profile = uni1 ; UniMRCP MRCPv1 Server

;unimrcp-profile = lv2 ; LumenVox MRCPv2 Server

unimrcp-profile = lv1 ; LumenVox MRCPv1 Server

;unimrcp-profile = nss2 ; Nuance MRCPv2 Server

;unimrcp-profile = nss1 ; Nuance MRCPv1 Server

; UniMRCP logging level. Options are:

log-level = DEBUG

; Preloaded grammars

[grammars]

;grammar-name = path-to-grammar-file

; MRCPv2 properties (recognizer and generic header fields)

; http://tools.ietf.org/html/draft-ietf-speechsc-mrcpv2-20#section-9.4

[mrcpv2-properties]

Recognition-Timeout = 20000

No-Input-Timeout = 15000

; MRCPv1 properties (recognizer and generic header fields)

; http://tools.ietf.org/html/rfc4463#section-8.4

[mrcpv1-properties]

Recognition-Timeout = 20000

No-Input-Timeout = 15000

1)Set theunimrcp-profiledirectiveto lv1 (LumenVox MRCPv1 Server).

Step 3: Configure the MRCP client profile by editing the lumenvox.xml file

Here you can find a working lumenvox.xml example (to be modified accordingly with your environment):

<?xml version="1.0" encoding="UTF-8"?>

<rtsp-settings id="LumenVox-RTSP-Settings">

</profiles>

</unimrcpclient>

1) Set the <server-ip>X.X.X.X</server-ip>sections pointing to the Lumenvox Media Server IP.

2) Set the <server-port>554</server-port>to the Lumenvox Media Server port.
