wpf - .net core 3.0 中的 Microsoft Speech

Question

我以前在 .net framework 中使用过 Microsoft Speech(不确定它是哪个版本)并且它确实有效。我的电脑上现在没有那个项目。我已经下载并安装了 Runtime 11 和 SDK 11 并在我的 .dll 项目中从 .net core 3.0 引用了 C:\Program Files\Microsoft SDKs\Speech\v11.0\Assembly\Microsoft.Speech.dll 。这是我现在在我的 ViewModel 中的内容:

.
.
.
using Microsoft.Speech.Synthesis;

namespace Read
{
    public class VM : INotifyPropertyChanged
    {
        SpeechSynthesizer synth;
        string inputText;
        public string InputText { get => inputText; set { inputText = value; OnPropertyChanged(); } }

        public Command Speak { get; set; }
        public Command Pause { get; set; }
        public Command Resume { get; set; }
        public Command Stop { get; set; }

        public VM()
        {
            synth = new SpeechSynthesizer();
            synth.SetOutputToDefaultAudioDevice();
            synth.Volume = 75;
            Speak = new Command(speak, (o) => synth.State != SynthesizerState.Speaking);
            Pause = new Command(pause, (o) => synth.State == SynthesizerState.Speaking);
            Resume = new Command(resume, (o) => synth.State == SynthesizerState.Paused);
            Stop = new Command(stop, (o) => synth.State == SynthesizerState.Speaking || synth.State == SynthesizerState.Paused);
        }

        void speak(object obj) => synth.SpeakAsync(InputText);
        void pause(object obj) => synth.Pause();
        void resume(object obj) => synth.Resume();
        void stop(object obj) => synth.SpeakAsyncCancelAll();

        #region Notify Property Changed Members
    }

    public class Command : ICommand ...
}

在 xaml 中，我有这些:

<Window ...>
    <Window.DataContext>
        <local:VM/>
    </Window.DataContext>
    <Grid Margin="5">
        <Grid.ColumnDefinitions>
            <ColumnDefinition Width="*"/>
            <ColumnDefinition Width="Auto"/>
        </Grid.ColumnDefinitions>
        <TextBox Text="{Binding InputText}" AcceptsReturn="True" TextWrapping="Wrap"/>
        <StackPanel Grid.Column="1">
            <StackPanel.Resources>
                <Style TargetType="Button">
                    <Setter Property="Margin" Value="5 0 0 5"/>
                </Style>
            </StackPanel.Resources>
            <Button Content="Speak" Command="{Binding Speak}"/>
            <Button Content="Pause" Command="{Binding Pause}"/>
            <Button Content="Resume" Command="{Binding Resume}"/>
            <Button Content="Stop" Command="{Binding Stop}"/>
        </StackPanel>
    </Grid>
</Window>

我想这就是我在之前的 Text2Speech 中所做的一切。现在有了所有这些，在我的 .net 核心项目中，它不起作用!

Microsoft Speech Platform SDK 11 与 .NET Core 不兼容。

Microsoft.CognitiveServices.Speech 是新的 .NET Standard 兼容 API，可用于 .NET Core。

您将在 GitHub 上找到 quickstart。官方文档是 here 。
