顶顶通呼叫中心中间件（基于FreeSWITCH）对接mrcp asr 和 tts配置

介绍

顶顶通呼叫中心中间件通过asrproxy程序对接各种asr和tts,本文主要讲解 asrproxy程序对接 mrcp v1 和 mrcp v2的配置。

asrproxy.json配置

asr配置

javascript 复制代码

    "asr":{
        "interface": {
            "mrcp": {
                "count": 0,
                "fault_threshold": 0,
                "fault_try_interval": 600,
                "type": "mrcp",
                "engine": "uni2",
                "grammar":"ahlt_ats.grxml",
                "appid": "",
                "key": "",
                "secret": ""
            }
        },
        "groups":{
            "default":{
                "mode":0,
                "enable":[
                 "mrcp"
                ]
            }
        },

grammar 语法配置文件，由ASR提供。
engine mrcp的配置文件client-profiles/unimrcp.xml里面配置的mrcp-profile

tts 配置

javascript 复制代码

            "mrcp": {
                "count": 0,
                "fault_threshold": 0,
                "fault_try_interval": 600,
                "type": "mrcp",
                "engine": "uni2-tts",
                "appid": "",
                "key": "",
                "secret": ""
            }
        },
        "groups":{
            "default":{
                "mode":1,
                "enable":[
                    "mrcp"
                ]
            }
        },

engine mrcp的配置文件client-profiles/unimrcp.xml里面配置的mrcp-profile

mrcp 配置

unimrcpclient.xml

主要设置本机IP和本机外网IP

xml 复制代码

  <properties>
    <!--
      If the attribute "type" is set to "auto", IP address is determined implicitly by the hostname.
      This is the default setting.
    -->
    <ip type="auto"/>

    <!--
      If the attribute "type" is set to "iface", IP address is determined by the specified name of
      network interface/adapter.
    -->
    <!-- <ip type="iface">eth0</ip>-->

    <!--
      IP address can also be specified explicitly.
    -->
     <ip>改成本机IP</ip> 
    <!--
    <ext-ip>如果mrcpserver是外网取消这个注释，这里设置本机外网IP </ext-ip>
	-->
    <!--
      Server IP address should be specified explicitly, unless the client and the server are located on
      the same host. The server IP address can also be specified per <sip-settings> and <rtsp-settings>.
    -->
    <!-- <server-ip>a.b.c.d</server-ip> -->
  </properties>

client-profiles/unimrcp.xml

主要配置mrcpv2 服务器IP和端口，如果mrcpv1配置V1对应的。
