Register the worker with PipelineRunner.add_workers() before calling run() instead. The worker argument still works but now emits a DeprecationWarning and will be removed in a future release. Update the runner docstrings, the run_test() helper, and all examples (including the asyncio.gather() forms) to use the new pattern.

|
|
|
This example will use diarization within our STT service and output the words spoken by
|
|
each individual speaker and wrap them with XML tags.
|
|
|
|
If you do not wish to use diarization, then set the `enable_diarization` parameter
|
|
to `False` or omit it altogether. The `text_format` will only be used if diarization is enabled.
|
|
|
|
By default, this example will use our ENHANCED operating point, which is optimized for
|
|
high accuracy. You can change this by setting the `operating_point` parameter to a different
|
|
value.
|
|
|
|
For more information on operating points, see the Speechmatics documentation:

https://docs.speechmatics.com/rt-api-ref
