textaccumulate
textaccumulate is an element that can be used to accumulate text prior to
translation or synthesis.
When working with live data, the element will accumulate input text until the deadline is reached, comparing the current running time with the running time of the input items and the upstream latency.
At this point the input items will be drained up until a configurable pattern is encountered, see the timeout-terminators for more information.
If the pattern does not match, the entire accumulator is drained.
The accumulator will also be drained upon receiving rstranscribe/final-transcript
and rstranscribe/speaker-change custom events.
When the user wants to use a very low / no latency upstream, and is willing to accept desynchronization in order to build up long-enough sentences for translation, they can set the lateness property to shift the input timestamps forward when accumulating.
