語音辨識（speech recognition）技術，也被稱為自動語音辨識（英語：Automatic Speech Recognition, ASR）、電腦語音識別（英語：Computer Speech Recognition）或是語音轉文字識別（英語：Speech To Text, STT），其目標是以電腦自動將人類的語音內容轉換為相應的文字；跟小夥伴們一起嘗試過NEMO還有Kaldi、MASR、VOSK，wav2vec以及Google、Azure等API，更別說後來陸續又出現SpeechBrain、出門問問的WeNet跟騰訊PIKA等。目前已知可訓練聲學模型(AM)中文語音(中國發音/用語，可惜還沒臺灣較靠譜的)公開數據如：Magic-Data_Mandarin-Chinese-Read-Speech-Corpus、aidatatang、aishell-1 、aishell-2等約2000多小時(aishell目前已到4，但想商用至少得破萬小時較靠譜)；再搭配語言模型(LM)，然後基於各種演算法架構優化各有優缺點，效果也各有優劣。與說話人辨識及說話人確認不同，後者嘗試辨識或確認發出語音的說話人而非其中所包含的詞彙內容。 語音辨識技術的應用包括語音撥號、語音導航、室內裝置控制、語音文件檢索、簡單的聽寫資料錄入等。語音辨識技術與其他自然語言處理技術如機器翻譯及語音合成技術相結合，可以構建出更加複雜的應用，例如語音到語音的翻譯。語音辨識技術所涉及的領域包括：訊號處理、圖型識別、概率論和資訊理論、發聲機理和聽覺機理、人工智慧等等。
