smaller Text at CueVoice

[Alexander Weidner]

Hello,

how can I get a smaller fontsize for text under a CueVoice?

I tried 

\font-size = #-2 

and other things,  but it did not work.

Cheers! Alexander

      \new Lyrics \lyricsto "Hirte" {
        \override Lyrics.font-size = #-3
         Naht der Him -- mel?
