FreeSWITCH界面安裝參考：https://blog.csdn.net/jia198810/article/details/137820796

1、docker地址

registry.cn-hangzhou.aliyuncs.com/pbx/asr-47m            latest    616 MB
registry.cn-hangzhou.aliyuncs.com/pbx/asr-14m            latest    588 MB
registry.cn-hangzhou.aliyuncs.com/pbx/asr-124m           latest    653 MB
registry.cn-hangzhou.aliyuncs.com/pbx/my-funasr          latest    6.5G

2、使用

2.1 下載

# 下載對應的asr地址
podman pull registry.cn-hangzhou.aliyuncs.com/pbx/asr-124m

2.2 運行

# asr-124m  中英文 124M
# sherpa-ncnn-streaming-zipformer-bilingual-zh-en-2023-02-13
# 啟動 -v為熱詞，可選，-e為變量，NUM_THREADS為最大線程，可選，下面的都一樣
podman run -itd -p 8000:8000/tcp -v /root/hotwords.txt:/root/hotwords.txt -e NUM_THREADS=4 --name asr-124m asr-124m
# 查看日志
podman exec -it asr-124m tail -f /var/log/asr.log # asr-14m  中文 14M
# sherpa-ncnn-streaming-zipformer-zh-14m-2023-02-23-chinese
podman run -itd -p 8000:8000/tcp -v /root/hotwords.txt:/root/hotwords.txt -e NUM_THREADS=4 --name asr-14m asr-14m# asr-47m  中英文 47M
# sherpa-ncnn-streaming-zipformer-small-bilingual-zh-en-2023-02-16-bilingual-chinese-english
podman run -itd -p 8000:8000/tcp -v /root/hotwords.txt:/root/hotwords.txt -e NUM_THREADS=4 --name asr-47m asr-47m# Funasr  啟動較慢
# 可以進入容器netstat -tnlp是否啟動8000和10095 ,
#`offline`表示推理模式為一句話識別；
#`online`表示推理模式為實時語音識別;
#`2pass`表示為實時語音識別，并且說話句尾采用離線模型進行糾錯；
# 用online吧，online效果還是可以的
podman run -itd -p 8000:8000 -p 10095:10095  -e MODE='online'  -v /root/hotwords.txt:/workspace/models/hotwords.txt --name my-funasr my-funasr

3、例子

3.1 下載

root@xiaojia-ts /h/xiaojia# podman pull registry.cn-hangzhou.aliyuncs.com/pbx/asr-124m                                                                                           (base)

3.2 啟動

root@xiaojia-ts /h/xiaojia# podman run -itd -p 8000:8000/tcp  -e NUM_THREADS=4 --name asr-124m asr-124m                                                                          (base)

3.3 編譯mod_audio_fork或者mod_audio_stream模塊使用

參考下面的地址，編譯該模塊，如果安裝了圖形化界面，自動mod_audio_fork模塊。
https://gitee.com/rasonyang/drachtio-freeswitch-modules/blob/main/modules/mod_audio_fork/README.md
https://github.com/amigniter/mod_audio_stream

編譯完成后，加載模塊

freeswitch@MyFs> load mod_audio_fork 
+OK Reloading XML
+OK

mod_audio_fork對應的api為

uuid_audio_fork <uuid> start <wss-url> <mix-type> <sampling-rate> <metadata>

3.4 編寫呼叫路由和呼叫腳本

呼叫路由

<extension name="11120-自定義ASR"><condition expression="^(11120)$" field="destination_number"><action application="python" data="handle-asr"/><action application="hangup"/></condition>
</extension>

呼叫腳本

#!/usr/local/python3/bin/python3
# -*- coding: utf-8 -*-
"""
處理語音識別結果
"""from freeswitch import *
import refsapi = API()def handler(session, args):# 接通session.answer()# 獲取uuiduuid = session.getVariable("uuid")# 執行api,把該uuid的audio發送到asr地址的8000（上面的容器映射的端口）,單聲道mono,采樣率16kcmd = "uuid_audio_fork {} start ws://192.168.1.70:8000/ mono 16k".format(uuid)fsapi.executeString(cmd)# 超時時間session.sleep(30000)

3.5 esl捕獲識別結果

連接esl，獲取"Event-Subclass": "mod_audio_fork::json"事件，_body為識別內容。

{"Event-Subclass":	"mod_audio_fork::json","Event-Name":	"CUSTOM","Core-UUID":	"5788c155-5b0e-48c9-8ec8-accd46623a0b","FreeSWITCH-Hostname":	"localhost.localdomain","FreeSWITCH-Switchname":	"MyFs","FreeSWITCH-IPv4":	"192.168.1.20","FreeSWITCH-IPv6":	"::1","中間很多內容，略過......""variable_playback_seconds":	"1","variable_playback_ms":	"1000","variable_playback_samples":	"8000","Content-Length":	"144","Content-Length":	"144","_body":	"{\"text\":\"今天是205年8月2號然后我在測試一個語音識別程序我主要想看一下原始月的準確度\",\"timestamp\":1754120626173}"
}

3.6 其他處理

識別結果拿到后，解析body內容，可以在esl里編寫程序，進行其他處理。
