  Recent results on the energy spectra in QCD jets are reported. Within the
Modified Leading Logarithmic Approximation (MLLA) and the Local Parton Hadron
Duality (LPHD) model one finds a very good description of the $e^+e^-$ data
from the lowest up to the LEP 1.5 energies. A model with fixed $\alpha_s$ can
be excluded, already in certain finite energy intervals. The fits also
extrapolate smoothly into the region of small particle energies, in particular,
the data follow a scaling prediction for the low energy limit derived from the
colour coherence of the soft gluon emission.
