I work on a Speech Science software development team at CaptionCall. We have developed a system that can run audio through a selection of various speech-to-text ASRs --- including your ibm-watson recognizer. A pip requirement for your recognizer is websocket-client==1.1.0, pinned to one value. Other recognizers allow for a range of values which adds to the flexibility of our software system, enabling multiple recognizers to be selected during one run, without having to change software environments multiple times.

Here's an example of one such conflict:

ERROR: Cannot install -r requirements_benchmark_asrs.txt (line 10) and rev-ai==2.13.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    ibm-watson 5.3.0 depends on websocket-client==1.1.0
    rev-ai 2.13.0 depends on websocket-client<1.0.0 and >=0.56.0
