unvoiced

Not spoken or expressed.

I could guess her unvoiced opinon.

Spoken without vibration of the vocal chords.

Both EE and SSBE feature glottal stops – unvoiced Ts – but in EE it can happen in the middle of words – eg “wa’er for “water” – whereas in SSBE it happens only at the end of words.

That does not contain voice.

The unvoiced signal is smaller energy than voiced signal and, so, this section is applied the smaller threshold.
