Libs or APIs for removing background noise from voice input?

What do you call the same phoneme that behaves a little bit differently in particular environments?
IMO this is a classical terminological question. In some views, by definition it is an "allophone". The phones are the detailed surface sounds, a symbolic representation of speech without prejudice to ...

Is it possible to automatically recognize a single syllable as its IPA transcription?
This is impossible in principle, at least in the form that you asked. A modified version of the task might be possible. The main reason is that the input would be an acoustic waveform, which needs to ...
