    "about": "Universal-3.5 Pro 是 AssemblyAI 的語音辨識模型，可將錄製的語音轉成文字。在 Sync 規格下，短音訊片段會在單次回應中產生完整逐字稿。這適合語音訊息、按住說話輸入，以及應用程式已知錄音何時應結束的獨立對話輪次。\n\n將音訊準備成範圍明確的片段。AssemblyAI 的 Sync 要求接受 80 毫秒至 120 秒的音訊，檔案大小上限為 40 MB。支援格式為 WAV，或有號 16 位元、小端序的原始 PCM。音訊可為單聲道或立體聲；立體聲會在內部混音為單聲道。支援的取樣率為 8、16、22.05、24、32、44.1 及 48 kHz。WAV 標頭會提供取樣率與聲道數；原始 PCM 則需要在轉錄設定中另外提供這些數值。\n\n錄下完整語句，並保留語音的開頭與結尾。一個實用的原創任務例子，是包含產品名稱、訂單識別碼及請求的簡短產品支援語音訊息。保留來源片段，讓逐字稿能與這些重要細節核對。較長的錄音應使用適合長篇轉錄的工作流程，不要將短片段的時長限制視為整個模型的音訊容量規格。\n\n結果包含完整逐字稿、附有逐詞信心分數的詞語清單，以及介於零與一之間的整體信心分數。結果也會提供提交音訊的時長及請求識別碼，讓文字能與原始片段保持關聯。可依詞語信心分數找出值得重新聆聽檢查的段落，尤其是對應用程式重要的名稱、數字及領域詞彙。\n\n詞語時間戳記為選用功能，預設關閉。要求此功能時，每個完成對齊的詞語都可附有相對於片段起點、以毫秒表示的開始與結束時間。開發商的規格在詞語無法對齊時會省略這些數值，而不會編造近似時間。時間戳記在英語音訊上的準確度最佳。準備詞語反白、可搜尋的波形或字幕對齊時，明確保留缺漏的時間資訊，並在將文字作為完成的字幕軌使用前，先與錄音核對。\n\n上下文提示用來描述錄音的主題。它可以指定領域、情境，或應用程式已知的特定細節，長度上限為 6000 個字元。先使用符合音訊的簡短描述，例如針對特定裝置的技術支援對話。提示提供辨識上下文，並不是要求將說話者的訊息改寫成另一種文件。\n\n獨立的關鍵詞清單可讓辨識偏向特定詞彙。Sync 規格最多接受 100 個詞語，整份清單合計上限為 8000 個字元。對於少見名稱、縮寫或產品術語，使用精確拼寫；一般容易辨識的詞語則不必加入。過長或不必要的詞語清單可能導致過度更正，因此應聚焦於錄音中重要的詞語。上下文描述與詞彙清單可以一起使用。\n\n先前的對話也有助於解讀簡短回覆。依時間順序由舊到新提供先前語句，而目前音訊仍是本次要轉錄的輪次。文件所列的上下文額度為 500 個輪次，或總計 16,000 個字元。若超過這些上限或模型可用上下文，會先移除最舊的項目。當簡短回答包含識別碼，或其指涉意義來自前一個問題時，這項功能特別有用。\n\n語言選擇會將辨識導向一種或多種預期語言。目前 Sync 介面接受 32 種語言代碼；未指定時預設使用英語。對於語碼轉換音訊，列出預期出現的語言。自訂上下文提示會取代系統管理的預設提示，並覆寫獨立的語言代碼引導，因此同時需要語言與情境上下文時，請在該提示中寫明預期語言。逐字稿應保留實際說出的語言，不要將轉錄視為翻譯指令。\n\n此模型也用於其他 AssemblyAI 轉錄工作流程，但 Sync 規格的短片段要求與結果欄位屬於此特定介面。開發商的 Dictation 工作流程另外加入文字清理階段；逐字稿與改寫後的訊息是不同產出。若後續編輯或摘要步驟產生整理後的版本，應保留辨識出的語音文字，讓原始措辭仍可供比較。\n\n實用產出包括轉錄後的語音訊息、助理的一個完整對話輪次、可供搜尋的短音訊文字，或供審閱介面使用的詞語時間清單。依錄音核對關鍵詞語、保留任何缺漏的對齊資訊，並維持片段與傳回文字的關聯。辨識結果為應用程式的下一步提供有來源依據的轉錄；回答請求或編輯訊息，則屬於外圍工作流程。",
