Windows 8 デスクトップのマイクからのリアルタイムの音素認識が必要です。そこで、 http: //cmusphinx.sourceforge.net/wiki/phonemerecognition に従い、VS2013 の Subversion ソースから pocketphinx_continuous をビルドしました。管理者としてコマンド ラインで実行します。

最後の INFO 行で、Windows 8 は次のエラーをスローします。
PocketSphinx のデバッグ出力またはコマンド ライン オプションに問題はありますか? それとも純粋な Windows の問題ですか? 次のフォルダーに気付きました: /bin/Release/Win32. 私の Windows 8 は Intel NUC で 64 ビットです。Sphinxbase.dll は Subversion からデバッグ モードでコンパイルされましたが、PacketSphinx にはリリース モードしかありませんでした。
また、音素のタイミング情報が利用できることをどこかで読みました-それを取得する方法は?
追加: Nikolay のアドバイスに従い、これらのパラメーターを使用して、エラーを排除しましたが、音素は得られませんでした:
