VoQS

Extracted from the Wikipedia article Voice Quality Symbols.
VoQS are normally combined with curly braces that span a section of speech, just as with prosody notation in the extended IPA (extIPA). In fact, they started off as part of extIPA before being split off. The symbols may be modified with a digit to convey relative degree of the quality. For example, ⟨V!⟩ is used for harsh voice, and {3V!...3V!} indicates that the intervening speech is very harsh. ⟨L̞⟩ indicates a lowered larynx. Thus, {L̞1V!...1V!L̞} indicates that the intervening speech is less harsh with a lowered larynx.
