"A simple and effective framework for A priori SNR estimation"

- Audio samples -

Below, we present some audio samples demonstrating the impact of the proposed pitch-adaptive decision-directed (PADDi) method. The audio samples consist of utterances spoken by male and female speakers, corrupted in different noise types.

Female speaker: ''Lori's costume needed black gloves to be completely elegant.'' in white noise, SNR = 5 dB:

Male speaker: ''Serve the coleslaw after I add the oil.'' in babble noise, SNR = 5 dB:

Male speaker: ''She was ready for her great adventures and the arrival of her mobile partner.'' in rain noise, SNR = 5 dB:

Male speaker in a cafe as an example for a real-world scenario. The recording was part of the Chime 4 challenge:
