Ich möchte einen sprachgesteuerten Rollstuhl mit Intel Edison implementieren. Grundsätzlich sage ich vorwärts, links, rechts und halte an einem Mikrofon, das über den Soundadapter an das Edison-Board angeschlossen ist .

Für den ersten Prototyp möchte ich nur die Ausgabe der Spracherkennung auf der CLI anzeigen.

Ich folge diesem Online-Tutorial. Alles ist gut bis zur Soundkonfiguration.

Als Nächstes befinden sich die CLI-Ausgänge der im Lernprogramm verwendeten Befehle.

Was muss ich tun, um das Problem zu beheben?

Ok, solved it. There was some problem with the .asoundrc file.

Replaced the content of .asoundrc with the following and it worked. Followed this link to solve it.

pcm.!default { type hw card 0 } ctl.!default { type hw card 0 }
