pythonでsoxを利用したいのですがsoxを認識してくれない

###pythonのプログラムでsoxを利用したい

vscodeで音声認識をしたくその過程でsoxを利用したいのですが下記のようなエラーメッセージ出たので解決方法を知りたいです

発生している問題・エラーメッセージ

python
'sox' is not recognized as an internal or external command,
operable program or batch file.
SoX could not be found!

    If you do not have SoX, proceed here:
     - - - http://sox.sourceforge.net/ - - -

    If you do (or think that you should) have SoX, double-check your
    path variables.

../data/original/jsut_ver1.1/basic5000/wav\BASIC5000_0001.wav
This install of SoX cannot process .wav files.

###試したこと
調べてみると同じエラーメッセージが出ている人がいてその人が解決したように自分も同じ方法をしてみました．
その人がしたこと

soxをインストールして同じディレクトリ内にsoxを移動

また自分はコマンドライン上に下記のコードを打ち込みパスを通そうとしましたが下記のようなエラーメッセージが発生しました

打ち込んだコード
path %path;C:Program Files (x86)\sox-14-4-2

発生したエラー

となり解決できませんでした
結局原因すらわからず困っています
特にsoxのインストールがうまくいっていないのかパスが通っていないのかすらわかりません．コードはいただいたものなので間違って位はいないと思います．
よろしくお願いします
