Sentence examples for speech hit rate from inspiring English sources

The speech hit rate and non-speech hit rate are calculated as follows: (10).

3) The LTSD-VAD algorithm yields the best speech hit rate while non-speech hit rate is poor.

Sohn-VAD algorithm yields a moderate behavior with relatively high speech hit rate but slightly low non-speech hit rate.

It can be concluded that: 1) Sohn-VAD algorithm yields a moderate behavior with relatively high speech hit rate but slightly low non-speech hit rate.

2) Harmfreq-VAD, LTSV-VAD, and LSFM-VAD algorithms also obtain a moderate behavior with relatively high non-speech hit rate but slightly low speech hit rate.

Experimental results show that among six analyzed algorithms, the proposed algorithm is the best one with the highest non-speech hit rate and a reasonably high speech hit rate.

Fig. 7 Speech/non-speech hit rates of the evaluated algorithms under different SNR levels.

However, since these parameters were adjusted to yield a low false alarm rate (which consequently results in a low hit rate), two additional values of were considered here, as an increase in yields a larger speech pause hit rate.

Non-speech hit rate (HR0).

Moreover, its non-speech hit rate is much better than all the other methods in all cases.
