Before revision:  This technique , termed Masked Acoustic Modeling (MAM), can also perform pre-training , for the first time, on any acoustic signals (including non-speech ones) without annotation.
After revision:  This technique , termed Masked Acoustic Modeling (MAM), not only provides an alternative solution to improving E2E-ST, but also can perform pre-training , for the first time, on any acoustic signals (including non-speech ones) without annotation.
