A speech aid system includes a tube (2) for mounting at a tracheostomy (901) of a user (900), a voice parameter acquiring device (4) mounted to the tube (2) and generating a voice parameter signal according to airflow applied within the tube (2) resulting from attempt by the user (900) to speak, a processor (5) generating an audio signal corresponding to the voice parameter signal, and a sound generator (7) for mounting in an oral cavity (902) of the user (900). The sound generator (7) produces a substitute glottal sound corresponding to the audio signal.一種人工發聲裝置,包含一安裝在氣管造廔的仿聲門氣管、分別安裝於仿聲門氣管之一聲音參數擷取器與一微處理器,及一安裝於病患口腔內的發聲器。仿聲門氣管內部設有一口徑較小的人工聲門,聲音參數擷取器可感測輸出仿聲門氣管內之氣流所產生的聲音參數訊號。微處理器可將聲音參數訊號轉換成一音源訊號,而驅使發聲器於口腔內發出一供病患講話構音的模擬喉音。透過仿聲門氣管、聲音參數擷取器、微處理器與發聲器的設計,可有效模擬正常人講話時的喉部聲門結構與喉音產生時間,可幫助病患像正常人說話一樣講出有聲音大小和明確斷句的正確語音。2‧‧‧仿聲門氣管21‧‧‧銜接段22‧‧‧仿聲門段220‧‧‧呼吸孔221‧‧‧管體部3‧‧‧氣孔開關4‧‧‧聲音參數擷取器5‧‧‧微處理器6‧‧‧遙控器61‧‧‧載具62‧‧‧開關單元621‧‧‧控制鈕64‧‧‧音頻調控單元641‧‧‧調控件7‧‧‧發聲器71‧‧‧第三無線通訊單元72‧‧‧發聲單元720‧‧‧聲音輸出面
