為生產級語音產品打造的語音轉文字與音訊智慧 API
透過 WebSocket 串流實現即時字幕，或透過 REST 提交檔案進行批次轉寫，支援 MP3、WAV、FLAC、Opus 等主流格式。
涵蓋 100 多種語言的自動語種偵測，對口音敏感，並支援同一句話中在多種語言間切換的情境。
說話者分離、命名實體辨識、PII 去識別化、情感分析與摘要，全部按需啟用、按需計費。
把轉寫結果直接送入大型語言模型，可使用 Gladia 代管模型或自帶模型（BYOM），用於生成摘要與結構化輸出。
面向生產級通話自動化的語音 AI 代理與即時語音轉文字
用自然語言描述代理，平台即自動設定語音、提示詞、知識與通話流程；接著測試、微調並部署到電話線、應用或 API。
串流轉寫在對方仍在說話時即回傳文字，透過 API 或內建 playground 支援數十種語言與口音。
把自有介面交給代理，使其能在通話中預約、查詢和更新紀錄，並把結果寫回 Salesforce、HubSpot 或 Zoho。
接入 Twilio 或 Plivo，將活動指向聯絡人名單，讓代理處理每一通電話，你只需管理佇列。
