配音員危！微軟VALL-E 2模型語音克隆達到配音員水準
微軟近期發佈了一款零樣本文本到語音（TTS）模型VALLE-2，該成果在技術界引發熱議，被認爲是TTS領域的里程碑。VALLE-2的創新之處在於其零樣本學習能力，僅需一小段陌生語音樣本，便能模仿聲音說任意文本，實現了驚人的即時模仿和編碼器分組。它還改進了重複感知採樣，提高解碼穩定性，並簡化了數據需求。在主觀評分和客觀指標的測試中，VALLE-2超越了前代模型VALLE，幾乎達到人類語音水平。然而，強大的語音模仿能力也引發了對Deepfake技術濫用的擔憂，特別是關於倫理考量和潛在風險，如模型對非英美口音處理能力及計算效率的改進空間。當前，微軟僅將其作爲研究項目，並強調了合成語音檢測和授權機制的重要性。未來在語音助手、內容創作等領域的應用值得期待，同時需要關注技術的倫理使用與風險防控。更多關於VALLE-2的信息可訪問項目頁面：Microsoft官網。
