[Kaldi-developers] DTMF and dialtone detection

[Daniel P. <dp...@gm...>]

Everyone,

Something that is sometimes needed is code to detect DTMF tones and dial
tones.  It would be good to have the option to remove them from the audio
in addition to detecting them (so we can correctly process speech that
occurs on top of DTMF tones).  And this ideally should be done in an
algorithm which can be in principle applied online, as the signal comes in.
Does anyone want to help with this?  If so, you might want to draft an
interface for this.
