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

    "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

            "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

  <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 ofnetwork 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 onthe 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。
