Currently, speech masking systems make use of pre-recorded speech signals to generate maskers. We have applied the bootstrap method used in machine learning techniques, and generated a masker as if many speech samples from a small amount of speech is available. We tested the proposed masker using two subjective indexes. We compared the bootstrap type online masker (BS), the ring buffer addition type online masker (AD) and 3 types of pre-recorded maskers. BS masker was found to be significantly higher than others, especially at the Target to Masker Ratio (TMR) of 5 dB. Next, we compared the BS and AD masker for speech intelligibility. As a result, the intelligibility reduction of the BS type masker was 0.39 points lower than the AD type masker at TMR 0 dB. |
