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.

Properties
drain-on-final-transcripts
“drain-on-final-transcripts” gboolean
whether the element should entirely drain itself when receiving rstranscribe/final-transcript events
Flags : Read / Write
Default value : true
drain-on-speaker-change
“drain-on-speaker-change” gboolean
whether the element should entirely drain itself when receiving rstranscribe/speaker-change events
Flags : Read / Write
Default value : true
extend-duration
“extend-duration” gboolean
whether the element should extend the duration of an item to match the start time of the next non-drained item, if any. This is useful when a speech synthesis element is further downstream.
Flags : Read / Write
Default value : false
extended-duration-gap
“extended-duration-gap” guint
Amount of milliseconds to preserve between items when extend-duration is true
Flags : Read / Write
Default value : 500
latency
“latency” guint
Amount of milliseconds to allow for accumulating
Flags : Read / Write
Default value : 3000
lateness
“lateness” guint
By how many milliseconds to shift input timestamps forward for accumulating
Flags : Read / Write
Default value : 0
timeout-terminators
“timeout-terminators” gchararray
A regex for finding preferred break points when draining on timeout
Flags : Read / Write
Default value : \,\s|\:\s|\;\s
