教育經歷
2007年10月至2008 年4 月，由Marie Curie Early Stage Training 項目支持，赴英國愛丁堡大學語音技術研究中心進行學術訪問；
2008年7月進入中國科學技術大學博士後流動站/安徽科大訊飛信息科技股份有限公司博士後工作站從事博士後科研工作；
2011年3月起任中國科學技術大學電子工程與信息科學系副教授。
研究方向
凌震華的主要研究領域包括語音合成、語音編碼、聲音轉換等。先後作為主要技術人員參與“基於HMM模型的高表現力多語種語音合成技術”（國家863十一五專題課題）、“高表現力多語種韻律建模研究”（國家自然科學基金項目）、“多語言語音合成關鍵技術與套用產品開發”（國家863十一五重點項目子課題）等國家科研項目並承擔核心研究工作。作為項目負責人承擔的國家科研項目有 “基於合成語音質量評估的語音合成方法研究”(中國博士後科學基金項目)和“結合發音動作參數的統計建模語音合成方法研究”（國家自然科學基金青年科學基金項目）。 凌震華在圍繞語音合成的相關核心技術領域進行了近十年的深入研究，取得了一系列國際領先的研究成果，並對語音合成系統的實際性能提升與產業套用做出了積極貢獻。完成發明專利申請7項（2項已獲授權）；參與了IEEE Transactions on Audio Speech and Language Processing以及ICASSP/Interspeech/ISCSLP等語音信號處理領域主流國際學術期刊與會議的論文評審工作。
