(a) Speech period, (b) noise period.
The speech period is the interval limiting two successive GCIs.
It is defined as the ratio between the glottal open phase duration and the speech period.
Between the second and third speakers, a short overlapping speech period is present.
This mechanism ensures that whenever a prolonged music (or speech) period is processed, the absolute value of the threshold is slowly decreased towards the minimal value.

To draw reliable conclusions from the distance measure during fullband detected single-talk speech periods, an SNR of Θ SNR2 has to be exceeded.
Cancellation of speech can occur when the VAD erroneously detects speech periods as noise periods, due to speech samples being added to the noise data correlation matrix in (5).
Since the packet losses actually affect the signal quality during speech periods, we also adopt the well-known objective speech quality measures such as WB-PESQ, segSNR, and fwSNRseg for the error criterion to measure the speech quality.
By increasing one or both of the parameters, the algorithm will detect more speech pauses, but at the same time, it will also detect more speech periods as noise. .
This VAD has been shown to have a low rate of speech periods falsely detected as noise even at low-input SNR of −10 dB [19], which is desirable in order to avoid deteriorations of the speech signals in the noise reduction process.
