Sentence examples for silence region from inspiring English sources

The tracking accuracy is then further improved by the inclusion of a silence region detection step and estimation of the noise-only covariance matrix.

The averaged SNR value was estimated as the ratio of the averaged frame energy to the averaged noise energy of the initial silence region in each test utterance.

In addition, we introduce online estimation of the noise covariance matrix based on detection of the silence region (for details of the detection method, see Section 3.2). Figure 1 depicts a block diagram of the overall tracking process.

In our experiments, we employed a simple SNR estimation method, where the noise power estimated from the initial silence region is used through the entire utterance without any update procedures.

We will show the results when the number of active speakers is estimated at each time step and the silence region detection step is included to eliminate the noise only frequencies.

In this figure, weight values seem smaller in silence regions and become larger in speech regions.

Another example is the silence regions that occur in a speech signal.

Second, the use of the N-best list can force low-probability phone hypotheses to be recorded, especially during silence regions.

The non-transcribed spacer region from the rDNA locus, NTS1-2, walsolso mildly upregulated (1.8-fold), although the significance of this is difficult to assess as the overall expression of this feature is low, as predicted based on its location in a transcriptionally silenced region [60].
