UnboundLocalError: local variable 'monologue' referenced before assignment

[me-kell]

In transcriber.py#L102 in the section where output_type == "json" the local variable monologue is referenced before assignment (see code and traceback below):

        elif self.args.output_type == "json":
            monologues = {"schemaVersion":"2.0", "monologues":[], "text":[]}
            for part in result:
                if part["text"] != "":
                    monologues["text"] += [part["text"]] # <- local variable 'monologue' referenced before assignment
            for _, res in enumerate(result):
                if not "result" in res:
                    continue
                monologue = { "speaker": {"id": "unknown", "name": None}, "start": 0, "end": 0, "terms": []}
                monologue["start"] = res["result"][0]["start"]
                monologue["end"] = res["result"][-1]["end"]
                monologue["terms"] = [{"confidence": t["conf"], "start": t["start"], "end": t["end"], "text": t["word"], "type": "WORD" } for t in res["result"]]
                monologues["monologues"].append(monologue)
            processed_result = json.dumps(monologues)
