The phrase "active speech" is correct and usable in written English.
It can be used to refer to speech that is dynamic, engaging, or involves direct communication, often in a context of public speaking or presentations.
Example: "The speaker's use of active speech captivated the audience and kept them engaged throughout the presentation."
Alternatives: "dynamic speech" or "engaging dialogue".
Voice activity detection (VAD) refers to the problem of distinguishing active speech from non-speech regions in an given audio stream, and it has become an indispensable component for many applications of speech processing and modern speech communication systems [1 3] such as robust speech recognition, speech enhancement, and coding systems.
The algorithm behavior presented in Section 6 only describes the performance in active speech regions.
47.06 % of the whole samples are labeled as active speech samples.
Figure 6 shows the SNR gain during active speech for both methods.
The purple points indicate an active speech session, the blue ones a data session, respectively.
Then, for every active speech segment, we measured the power ratio (18) and calculated its temporal mean separately.
These results and imaging data [19], support the notion of a "phonological resonance" allowing for an automatic recruitment of motor structures active during speech production and also during speech processing.
No regions were more active for speech > song in the autism group, while this same contrast in the control group yielded greater speech related activation left inferior frontal gyrus and posterior regions, including superior temporal, middle temporal and angular gyri (Fig. 2E and Supplementary Table 1).
With a suitable choice of T ϕ,k, the noise estimation update controller ϕ(n) becomes active during speech segments while still being able to adapt to changing noise levels.
No regions in autistic children were more active for speech stimulation than in controls.
Second, in the current study the motor excitability was measured during passive observation of the stimuli, not during active visual speech perception tasks.
