Hello,

To suppress the repetition, adjust bound-details.left-broken.text,
which by default is taken from bound-details.left.text.

\version "2.22.0"

{
  c1
    \tweak bound-details.left.text "Crescendo poco a poco"
    \tweak bound-details.left-broken.text ""
    \startTextSpan
  \repeat unfold 20 { c1 }
  1\stopTextSpan
}

There is currently no proper way to intersperse words throughout a
text spanner. A clever workaround was suggested by David Kastrup
on issue 3373 (https://gitlab.com/lilypond/lilypond/-/issues/3373):

\version "2.22.0"

\new Score \with {
  \override SpacingSpanner.spacing-increment = 3
}
<<
  \new Lyrics \lyricmode {
    \override LyricText.font-shape = #'italic
    \override LyricHyphen.dash-period = 3
    \override LyricHyphen.Y-offset = #-0.5
    Crescendo1 --
    poco --
    a --
    poco
  }
  {
    c1 1 1 1
  }
>>

Best regards,
Jean
