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。
首段音訊低至 50 毫秒的即時語音 AI API
文字轉語音、語音轉文字與即時語音對語音翻譯首段音訊約 50 毫秒，專為對話式代理最佳化，而非批次處理。
可用短樣本快速複製音色，也可選擇生產級專業複製，或僅憑文字描述生成全新聲音。
WebSocket 串流、Python 與 Rust SDK、自訂詞彙、語意化 VAD 與語碼切換，讓代理開發者易於整合。
Phonon 是 Gradium 開放可用的 TTS 模型，可在端側執行，適用於離線或隱私敏感部署。
專項更強Provides Whisper via API for robust speech-to-text, but lacks specialized real-time streaming audio intelligence pipelines.
Offers cost-effective batch transcription APIs powered by distributed cloud hardware rather than dedicated streaming infrastructure.
