The FLAC: Free Lossless Audio Codec


(Claudio Pelosi) #1

I am working on the implementation of a “Speech recognition” and I need flack, I am using freepbx with Asterisk Version: 13.13.1 and FreePBX 13.0.197.22
How do i know if i support flac?

You’d need to be specific about what “I need flack” means. Are you referring to a package (such as from the distro)? Are you referring to Asterisk recording to a flac file?

I am using the freepbx distro.
I am implementing this: https://zaf.github.io/asterisk-speech-recog/

As you can see it requires flac “Free Lossless Audio Codec” , how can I verify that it is supported

Looks to me is as though people use an external utility to transcode to FLAC, for this:

Google should turn up quite a few worked examples of using Google cloud speech to text with Asterisk, including for IVR type uses, as well as voicemail to email.
