Sentence examples for directional speech from inspiring English sources

It was also suggested to exploit the position information to estimate the cross PSDs of directional speech interferences [18].

Figure 4 Percentage of correctly detected samples for directional speech-shaped noise as interferer, at different SNR and for β = 0.1, 0.2 and 0.3.

In Figure 4 the percentages of correct scores are shown for the directional speech-shaped noise for (solid curve), (dashed curve) and (dotted curve).

While the improvement for directional speech-shaped noise in Figure 5 actually increases with decreasing SNR when employing a perfect VAD, this is not the case for diffuse babble noise (Figure 7), where a 1 dB decrease is seen.

This increase is modest at higher input SNR but becomes progressively greater at lower SNR. Figure 6 Intelligibility weighted speech cancelation for directional speech-shaped noise at different SNRs for perfect VAD and envelope-based VAD with β = 0.1, 0.2 and 0.3.

Below an input SNR of 0 dB, the noise suppression gradually decreases for all settings, and eventually amounts to roughly 15 dB at an input SNR of −10 dB. Figure 5 Intelligibility weighted SNR improvement for directional speech-shaped noise at different SNRs for perfect VAD and envelope-based VAD with β = 0.1, 0.2 and 0.3.

This directional-power-ratio measure was shown to properly estimate the ratio between the direct speech and the reverberation amount, yielding a well-founded signal-based quality measure and a blind DRR estimator.

"It's more directional than speech.

Many are large (a river) and directional (human speech), some are partially occluded by objects (a prey hiding in a bush).

Modest off-axis orientation still results in directional benefit: speech intelligibility can increase for signals up to 30° off-axis when using directional microphones (Ricketts 2000; Henry & Ricketts 2003).

Parentally, we suggested practicing greetings and numbers and directional words.
