In order to keep each language in sync with the visual content,
you need to exercise fine-grained control over the duration of
each segment. That's where this new feature comes in. You can
now specify the maximum desired duration for any desired segments,
counting on Polly to adjust the speech rate in order to limit
the length of each segment.

Para mantener cada idioma sincronizado con el contenido
visual, es necesario ejercer un control detallado sobre
la duración de cada segmento. Ahí es donde entra esta
nueva característica. Ahora puede especificar la
duración máxima deseada para los segmentos deseados,
contando con que Polly ajuste la velocidad de voz para
limitar la longitud de cada segmento.
