Re-record many system prompts in one call. Provide a filenames array; each prompt's script/voice defaults are resolved per-file (overridable by top-level voice fields). The remote TTS calls are issued in parallel (concurrency capped by NsSpeechWordBulkConcurrency, default 8) and the request returns only once every file has finished. Already-current files are skipped (no synthesis).
