Bad call recording quality

[Aditya Bisht]

I am using Unimrcp with LUA with google TTS and ASR but I am facing issues with the call recording the voice of the caller and the callee are overlapped with each other and it results in very bad quality of speech, here are the lines of code from the dialplan which I am using to record the call,

<action application="set" data="RECORD_STEREO=true"/>
<action application="record_session" data="${base_dir}/${strftime(%Y-%m-%d-%H-%M-%S)}.wav"/>

Please do let me know if there are any other details required to resolve this problem.

Thanks

Aditya

Hi Aditya,

Call recording in FreeSWITCH should not have an impact on the ASR or TTS functionality. Do you observe the same problem if call recording is disabled?

Hello Arsen,

I am sorry for not being able to explain you earlier but the issue is when I use this TTS and ASR the quality of the recording is not good, it is kinda distorted with both the voices of the caller and callee overlap with one another, and the call quality is good, hope I was able to clarify this time.

Thanks

Hello Pratik,

The description of the problem is now clear but you would need to narrow down the problem within FS.
