Function applyModulateTranscript

applyModulateTranscript(
    input: {
        kind: "partial" | "final";
        text: string;
        finalizedPrefix: string;
        sourceLanguage: string;
    },
): { finalizedPrefix: string; events: StreamingAsrEvent[] }
Soft-splits Modulate cumulative partials / finals into caption-sized hub events.

Modulate has no endpointing knob — continuous sermon speech often arrives as one multi-sentence utterance. We finalize sentence-sized chunks from growing partial_utterance text (and flush any remainder on the provider final).
Parameters
- input: {
      kind: "partial" | "final";
      text: string;
      finalizedPrefix: string;
      sourceLanguage: string;
  }
  Latest frame kind/text plus text already emitted as finals.
Returns { finalizedPrefix: string; events: StreamingAsrEvent[] }
Updated finalized prefix and zero or more hub events (in order).
