Estive trabalhando em um projeto envolvendo comandos de voz e pegando um exemplo da própria Microsoft. Parece simples, tirando o fato de que não consigo setar o Audio Device Padrão.
recognizer.SetInputToDefaultAudioDevice()
Sempre me apresenta um erro: Additional information: Cannot find the requested data item, such as a data key or value.
O problema é que tenho um dispositivo definido como padrão na máquina, tanto de saída como de entrada.
Imports Microsoft.Speech.Recognition
Imports System.Runtime.Remoting.Contexts
Public Class TesteVC
' Handle the SpeechRecognized event.
Private Shared Sub recognizer_SpeechRecognized(sender As Object, e As SpeechRecognizedEventArgs)
MsgBox("Texto: " + e.Result.Text)
End Sub
Private Sub TesteVC_Load(sender As Object, e As EventArgs) Handles Me.Load
Using recognizer As New SpeechRecognitionEngine(New System.Globalization.CultureInfo("pt-BR"))
Dim services As New Choices(New String() {"Oi Jarvis", "Olá Jarvis", "Jarvis"})
Dim cities As New Choices(New String() {"Verde", "Vermelho", "Azul"})
Dim findServices As New GrammarBuilder("Find")
findServices.Append(services)
findServices.Append("near")
findServices.Append(cities)
Dim servicesGrammar As New Grammar(findServices)
recognizer.LoadGrammarAsync(servicesGrammar)
AddHandler recognizer.SpeechRecognized, New EventHandler(Of SpeechRecognizedEventArgs)(AddressOf recognizer_SpeechRecognized)
recognizer.SetInputToDefaultAudioDevice()
recognizer.RecognizeAsync(RecognizeMode.Multiple)
While True
Console.ReadLine()
End While
End Using
End Sub
End Class
Agradeceria se pudessem me ajudar, obrigado desde já.
