Speech 语音识别与合成

通过麦克风语音采集转换为文字（STT），或者通过文字通过语音朗读出来（TTS）
本组件依赖于 BootstrapBlazor.AzureSpeech，使用本组件时需要引用其组件包

Demo https://www.blazor.zone/speechs

Nuget 包安装

使用 nuget.org 进行 BootstrapBlazor.AzureSpeech 组件的安装

.NET CLI

dotnet add package BootstrapBlazor.AzureSpeech

PackageReference

注册服务

Program.cs

// 增加语音服务
builder.Services.AddBootstrapBlazorAzureSpeech();

使用服务

// 语音识别服务
[Inject]
[NotNull]
private RecognizerService? RecognizerService { get; set; }

// 语音合成服务
[Inject]
[NotNull]
private SynthesizerService? SynthesizerService { get; set; }

1. Recognizer 语音识别, 通过语音采集设备将语音转化为文本

点击开始识别后对录入语音进行识别

@page "/recognizers"
@using BootstrapBlazor.Components
@using Microsoft.AspNetCore.Components

### Recognizer 语音识别

#### 通过语音采集设备将语音转化为文本

    **使用说明：**

    点击 **开始识别** 后，脚本运行可能会提示要求录音权限，授权后开始讲话，稍等一下，右侧文本框显示语音识别结果，请勿讲完话后直接点击 **结束识别**

@code{ 
    [Inject]
    [NotNull]
    private RecognizerService? RecognizerService { get; set; }

    private bool Start { get; set; }

    private string? Result { get; set; }

    private string ButtonText { get; set; } = "开始识别";

    private async Task OnStart()
    {
        if (ButtonText == "开始识别")
        {
            Start = true;
            ButtonText = "结束识别";
            await RecognizerService.RecognizeOnceAsync(Recognize);
        }
        else
        {
            await Close();
        }
    }

    private async Task OnTimeout()
    {
        await Close();
    }

    private Task Recognize(string result)
    {
        Result = result;
        Start = false;
        ButtonText = "开始识别";
        StateHasChanged();
        return Task.CompletedTask;
    }

    private async Task Close()
    {
        await RecognizerService.CloseAsync(Recognize);
    }
}

2.Synthesizer 语音合成,将文本内容转化为语音

点击开始合成后对文本内容进行语音合成

@page "/synthesizers"
@using BootstrapBlazor.Components
@using Microsoft.AspNetCore.Components

### Synthesizer 语音合成

#### 将文本内容转化为语音

@code{
    [Inject]
    [NotNull]
    private SynthesizerService? SynthesizerService { get; set; }

    private bool Start { get; set; }

    private string? InputText { get; set; }

    private string ButtonText { get; set; } = "开始合成";

    private string ButtonIcon { get; set; } = "fa fa-fw fa-microphone";

    private bool IsDisabled { get; set; }

    private async Task OnStart()
    {
        if (ButtonText == "开始合成")
        {
            IsDisabled = true;
            ButtonIcon = "fa fa-fw fa-spin fa-spinner";
            await SynthesizerService.SynthesizerOnceAsync(InputText, Recognize);
        }
        else
        {
            await Close();
        }
    }

    private Task Recognize(SynthesizerStatus status)
    {
        if (status == SynthesizerStatus.Synthesizer)
        {
            Start = true;
            IsDisabled = false;
            ButtonIcon = "fa fa-fw fa-spin fa-spinner";
            ButtonText = "停止合成";
        }
        else
        {
            Start = false;
            IsDisabled = false;
            ButtonIcon = "fa fa-fw fa-microphone";
            ButtonText = "开始合成";
        }
        StateHasChanged();
        return Task.CompletedTask;
    }

    private async Task Close()
    {
        await SynthesizerService.CloseAsync(Recognize);
    }
}
